Teams that run HubSpot and Klaviyo side by side usually discover the same problems within a quarter:
contacts exist in both platforms with conflicting details, because a CRM update in HubSpot never reaches the marketing profile in Klaviyo,
engagement data lives in silos, so a sales rep working a deal has no visibility into which email flows the prospect is receiving,
and someone on the team is making a decision based on subscriber data that drifted out of sync weeks ago.
However, the two platforms ended up coexisting (a B2B sales team running HubSpot while the ecommerce arm runs Klaviyo, a marketing team adopting Klaviyo for email and SMS while the CRM stays in HubSpot, or separate departments choosing tools independently), the longer they operate without a connection, the more customer data diverges and the harder it becomes to coordinate sales and marketing.
Connecting HubSpot and Klaviyo closes that gap.
Contacts created or updated in HubSpot flow into Klaviyo so marketing campaigns target accurate, current records. Lifecycle stage changes, deal milestones, and form submissions in HubSpot can trigger personalized email and SMS flows in Klaviyo, so outreach responds to real buyer behavior rather than lagging behind it.
Engagement data from Klaviyo (opens, clicks, purchases) can feed back into HubSpot so sales reps see how a contact is interacting with the brand.
A native integration exists: Klaviyo for HubSpot (by KAV Labs) is available in the HubSpot Marketplace and provides bidirectional contact and engagement data sync.
For teams that need different workflows or more customization, third-party tools like Zapier and Outfunnel offer alternative connection methods. Custom API development is also possible, since both platforms expose REST APIs. Each method differs in setup complexity, sync direction, data coverage, and cost.
One problem no connection method solves: the sync moves records between systems, but it does not verify whether those records are accurate, complete, or current.
That is where ZoomInfo comes in. ZoomInfo integrates natively with HubSpot through its marketplace and offers API and MCP access that can feed verified, enriched B2B data into any system, so the records flowing between HubSpot and Klaviyo are accurate and complete before they sync.
This article covers the full landscape of the HubSpot-Klaviyo integration: which methods are available, what data each one handles, how to set them up, the use cases that justify connecting both platforms, and the limitations to plan for. It also covers how ZoomInfo fits into the picture as a data enrichment layer for both platforms.
Let's start with an overview of the integration.
Integration Overview
Source: Klaviyo
Does a native integration exist?
Yes. Klaviyo for HubSpot (by KAV Labs) is available in the HubSpot App Marketplace and in the Klaviyo App Marketplace. It provides bidirectional sync of contacts and marketing engagement data between the two platforms. Additional integrations are available through Outfunnel and Zapier.
What data can sync?
Contacts, contact properties, list/segment memberships, lifecycle stages, form submissions, and marketing engagement data (email opens, clicks, unsubscribes). The specific fields and objects depend on the method. The native integration handles contact sync and engagement data bidirectionally. Third-party tools can map additional objects and custom properties.
Is the sync bidirectional?
The native Klaviyo for HubSpot integration supports bidirectional contact sync. Third-party tools like Zapier handle one-way flows per automation (a second Zap is needed for the reverse direction). Outfunnel specializes in marketing-to-CRM engagement data sync.
Is it real-time or batch?
The native integration syncs contacts in near real-time as records are created or updated. Zapier triggers fire within 1 to 15 minutes depending on plan tier. Custom API integrations can achieve real-time sync through webhooks on both platforms.
What are the available methods?
Native integration (Klaviyo for HubSpot), third-party automation (Zapier, Outfunnel), and custom API development.
Method | Setup Difficulty | Data Flow | Real-time? | Cost |
|---|---|---|---|---|
Native (Klaviyo for HubSpot) | Low | Bidirectional | Near real-time | Free (included with both platforms) |
Zapier | Medium | One-way per Zap | Near real-time (1-15 min) | From $19.99/mo |
Outfunnel | Medium | Marketing-to-CRM | Near real-time | From $19/mo |
Custom API | High | Fully customizable | Real-time via webhooks | Developer time + hosting |
One distinction worth settling upfront: the native integration handles ongoing, automatic sync of contacts and engagement data as part of daily workflows.
Zapier and Outfunnel handle event-triggered flows for specific use cases the native connector may not cover. Custom API development is the only method with no ceiling on what data objects and logic it can support, but it requires engineering resources to build and maintain.
Integration Methods
Native Integration (Klaviyo for HubSpot)
How it works: The Klaviyo for HubSpot integration (by KAV Labs) connects the two platforms through the HubSpot App Marketplace. Once installed, it syncs contact records and marketing engagement data bidirectionally between HubSpot's CRM and Klaviyo's customer profiles. Contacts created or updated in either platform propagate to the other, keeping both systems aligned without manual data entry.
Source: HubSpot
What it syncs: Contact records (name, email, phone, company, custom properties), list and segment memberships, HubSpot lifecycle stages, form submission data, and Klaviyo marketing engagement data (email opens, clicks, unsubscribes). The integration maps HubSpot contact properties to Klaviyo profile properties so both platforms carry consistent data.
Fits: ongoing bidirectional sync of contacts and engagement data; suited for teams that need both platforms to stay current as part of daily operations.
Setup process:
In HubSpot, navigate to Settings > Integrations > App Marketplace and search for "Klaviyo." Select the Klaviyo for HubSpot app by KAV Labs.
Click "Install app" and authorize the connection by granting the required permissions in both HubSpot and Klaviyo. You will need admin access in both platforms.
In the integration settings, configure which contact properties should sync between the two platforms. Map HubSpot contact fields to their corresponding Klaviyo profile properties.
Choose the sync direction for each field (HubSpot to Klaviyo, Klaviyo to HubSpot, or bidirectional) and set conflict resolution rules for fields that may be updated in both systems.
Select which HubSpot lists or Klaviyo segments should trigger sync events, and configure any filters to control which contacts are included.
Test the integration by creating or updating a contact in one platform and verifying the change appears in the other within a few minutes.
Strengths: The simplest setup path, requiring no third-party tool or engineering resources. Bidirectional sync keeps both platforms aligned without duplicate workflows. Included at no additional cost beyond existing HubSpot and Klaviyo subscriptions. Handles the most common sync scenario (contacts and engagement data) out of the box.
Limitations: KAV Labs maintains the integration, not HubSpot or Klaviyo, so update cadence and support depend on that developer. Custom objects and complex data models beyond standard contact properties may require additional configuration or may not be supported. The depth of field mapping and conflict resolution depends on the app's feature set, which may lag behind changes in either platform's API.
Best for: Teams that need a straightforward, low-maintenance connection between HubSpot and Klaviyo for contact and engagement data sync. Marketing teams running email and SMS campaigns in Klaviyo while managing the sales pipeline in HubSpot.
Zapier
How it works: Zapier connects HubSpot and Klaviyo through event-driven automations called Zaps. Each Zap pairs a trigger (an event in one app) with one or more actions (what happens in the other).
Source: Zapier
Both platforms are well-supported Zapier connectors, so the available trigger-action combinations cover the major objects and events. Zapier is useful for workflows the native integration does not cover, such as syncing deal stage changes or triggering Klaviyo flows based on specific HubSpot form submissions.
What it syncs: Contacts, deals, form submissions, list memberships, and custom properties. Each object type requires its own Zap. Zapier can push HubSpot deal data into Klaviyo as custom profile properties or events, enabling marketing automation based on sales pipeline activity. Custom fields can be mapped manually in the setup flow.
Fits: ongoing sync of specific events or objects not covered by the native integration; not a migration tool.
Setup process:
Create a Zapier account and connect both your HubSpot and Klaviyo accounts using OAuth.
Choose a trigger app (e.g., HubSpot) and select the trigger event (e.g., "New Deal" or "New Form Submission").
Choose the action app (Klaviyo) and select the action (e.g., "Add Member to List" or "Track Event").
Map fields between the two platforms. Zapier displays all available fields from both sides and lets you pull data from the trigger step into the action fields.
Test the Zap with a sample record to verify the field mapping produces the expected result in Klaviyo.
Turn the Zap on. For bidirectional sync on the same object, create a second Zap with the trigger and action apps reversed, and add a filter to prevent infinite loops.
Strengths: Handles use cases the native integration does not cover, such as syncing deal stage changes, form submissions, or custom events. No engineering resources required.
Zapier's filter and formatting steps add conditional logic (e.g., only sync contacts from specific HubSpot lists, or only trigger Klaviyo events for deals above a certain value). A large template library covers common HubSpot-Klaviyo workflows.
Limitations: Each Zap handles one trigger-action pair, so syncing multiple objects requires multiple Zaps (each counting against your plan's task allocation). Bidirectional sync needs duplicate Zaps with loop-prevention logic. No built-in deduplication. Historical records created before the Zap was activated do not sync. Zapier charges by task count, and high-volume syncs accumulate costs.
Best for: Teams that need to sync specific objects or trigger specific workflows between HubSpot and Klaviyo beyond what the native integration supports. Mid-size teams with conditional sync requirements (e.g., only sync contacts that reach a certain lifecycle stage, or trigger Klaviyo flows based on HubSpot deal activity).
Outfunnel
How it works: Outfunnel is a marketing-to-sales data connector built for bridging marketing engagement platforms with CRMs. It pushes marketing engagement data (email opens, clicks, web visits, form fills) from tools like Klaviyo into CRM platforms like HubSpot, and syncs contact lists bidirectionally.
Unlike general-purpose automation tools, Outfunnel is designed for the specific job of connecting marketing activity to sales context.
Source: Outfunnel
What it syncs: Contact records bidirectionally between HubSpot and Klaviyo, plus Klaviyo email engagement data (opens, clicks, unsubscribes) pushed into HubSpot as activity records. Web visit tracking data can also flow into HubSpot to give sales reps visibility into prospect behavior. Contact list sync keeps audiences aligned across both platforms.
Fits: ongoing sync with a focus on feeding marketing engagement data into the CRM for sales team visibility.
Setup process:
Create an Outfunnel account and connect both HubSpot and Klaviyo via OAuth.
Select the sync direction: contact data from HubSpot to Klaviyo, Klaviyo to HubSpot, or bidirectional.
Map contact fields between the two platforms. Outfunnel auto-maps standard fields and lets you manually map custom properties.
Enable engagement data sync to push Klaviyo email activity (opens, clicks, unsubscribes) into HubSpot contact timelines.
Configure any filters to control which contacts are included in the sync (e.g., only contacts in specific HubSpot lists or Klaviyo segments).
Activate the connection and verify data is flowing correctly by checking a known contact in both platforms.
Source: Outfunnel
Strengths: Built for the marketing-to-CRM data flow use case. Engagement data appears on HubSpot contact timelines, giving sales reps direct visibility into how contacts interact with Klaviyo campaigns. Bidirectional contact sync with field mapping. Simpler to configure than Zapier for this use case because the tool was designed for it rather than for general-purpose automation.
Source: Outfunnel
Limitations: Narrower scope than Zapier or custom API development. Does not handle workflow automation beyond contact sync and engagement data. Not designed for syncing deals, tickets, or custom objects. Adds another subscription cost on top of HubSpot and Klaviyo.
Best for: Sales teams that need Klaviyo email engagement data visible inside HubSpot contact records for follow-up prioritization, without building custom Zaps or API integrations.
Custom API Integration
How it works: Both HubSpot and Klaviyo provide REST APIs. HubSpot's API covers all CRM objects (contacts, companies, deals, tickets, custom objects) with webhook support for real-time event notifications. Klaviyo's REST API follows the JSON:API specification and covers profiles, events, campaigns, flows, lists, segments, and more, with webhook support for email, SMS, and push events.
Source: Klaviyo
A custom integration connects these APIs directly, with your own middleware handling authentication, field mapping, transformation, and error recovery.
What it syncs: Anything both APIs expose. This is the only method that supports complex sync scenarios like pushing HubSpot deal data as Klaviyo custom events, syncing custom objects, triggering Klaviyo flows based on HubSpot workflow events, or enforcing business rules that go beyond field mapping.
Fits: either one-time migration or ongoing sync; the only method with no ceiling on either.
Setup process:
Register API credentials in both platforms. In HubSpot, create a private app with the required scopes and generate an access token. In Klaviyo, generate a private API key with the appropriate permissions in Account Settings.
Design the data model mapping between HubSpot objects and Klaviyo resources, including field-level transformations and a cross-reference table for matching record IDs.
Build the sync service: a server-side application that listens for webhooks from both platforms, transforms data according to the mapping, and writes changes to the other side.
Implement conflict resolution logic for bidirectional sync (timestamp-based, source-priority, or field-level rules).
Add logging, error handling, and retry logic. Both APIs have rate limits (HubSpot's private app limits scale by plan tier; Klaviyo's tiered rate limits enforce per-second and per-minute windows).
Deploy, monitor, and maintain the integration over time.
Strengths: Complete control over what syncs, when, and how. Real-time sync via webhooks on both sides. Can implement complex business logic. No per-record or per-operation fees from a third-party connector. The only method that can sync custom objects, custom events, and complex multi-step workflows.
Limitations: Requires development resources to build and maintain. You own the infrastructure, monitoring, and error recovery. API changes on either platform (HubSpot introduced date-based API versioning in March 2026; Klaviyo follows a documented versioning and deprecation policy) require ongoing maintenance. The initial build takes weeks, not hours.
Best for: Teams with sync requirements that no off-the-shelf tool can satisfy. Organizations with in-house development teams and complex data models spanning both platforms. Companies that need to sync custom objects, enforce business logic during sync, or integrate HubSpot and Klaviyo into a broader multi-system data architecture.
Key Use Cases
1. B2B Lead Nurture Triggered by CRM Lifecycle Stage
A B2B company runs its sales pipeline in HubSpot and its email marketing in Klaviyo. When a HubSpot contact reaches the "Marketing Qualified Lead" lifecycle stage, the integration syncs that status change to Klaviyo, triggering a nurture flow with educational content, case studies, and product walkthroughs.
The sales team sees in HubSpot whether the contact engaged with the Klaviyo emails, informing follow-up timing.
Best integration method: Native integration for contact sync, supplemented by Zapier for lifecycle-stage-triggered Klaviyo events.
2. Ecommerce Purchase Data Feeding CRM Reporting
A company uses Klaviyo for ecommerce email and SMS marketing (connected to Shopify) and HubSpot as the CRM for its B2B wholesale arm. Purchase data and customer engagement from Klaviyo sync into HubSpot so the sales team can see each account's retail and wholesale activity. Closed deals in HubSpot sync back to Klaviyo to suppress active customers from prospecting campaigns.
Best integration method: Custom API (bidirectional with business logic to route data between B2B and B2C contexts).
3. Unified Contact Database Across Sales and Marketing
A growing company adopted HubSpot for CRM and Klaviyo for email marketing at different stages. Contacts entered through HubSpot forms need to appear in Klaviyo for marketing campaigns, and contacts acquired through Klaviyo signup forms need to appear in HubSpot for sales follow-up.
The native integration keeps both databases aligned, eliminating manual CSV exports and reducing duplicate records.
Best integration method: Native integration (Klaviyo for HubSpot) for bidirectional contact sync.
4. Sales Rep Visibility into Email Engagement
SDRs and AEs in HubSpot need to know which prospects are opening, clicking, and engaging with Klaviyo email campaigns before making outreach calls. Outfunnel or the native integration pushes Klaviyo engagement data into HubSpot contact timelines, so reps can see that a prospect clicked a product comparison email three times this week and tailor their follow-up accordingly.
Best integration method: Outfunnel (specializes in marketing engagement data flowing to CRM) or native integration.
5. Event-Driven Automation Across Platforms
A SaaS company wants to trigger a Klaviyo win-back SMS flow when a HubSpot deal is marked "Closed Lost," or add a contact to a Klaviyo VIP segment when a HubSpot deal closes above a certain value. These event-driven, conditional workflows require logic that the native integration does not support. A Zapier Zap with filters handles each scenario without engineering resources.
Best integration method: Zapier (event-triggered with conditional logic).
Limitations and Considerations
Different Data Models
HubSpot is a B2B CRM with contacts, companies, deals, and tickets as core objects. Klaviyo is a B2C marketing platform built around profiles, events, and ecommerce data (orders, carts, products). These data models do not map one-to-one. HubSpot's "Company" object has no direct equivalent in Klaviyo.
Klaviyo's event-based data model (tracking every click, browse, and purchase as a discrete event with unlimited retention) does not translate cleanly into HubSpot's activity timeline structure. Teams syncing between the two need to decide which HubSpot objects map to which Klaviyo properties, and accept that some data will not transfer without transformation.
Sync Conflicts
Bidirectional sync creates the risk of conflicting updates. If a marketing team updates a contact's email preference in Klaviyo while a sales rep updates the same contact's phone number in HubSpot, both changes need to propagate without overwriting each other.
The native integration handles this for mapped fields, but teams should configure conflict resolution rules during setup. Most third-party tools default to "last write wins," which may not produce the right answer for every field.
Pricing Implications
The native Klaviyo for HubSpot integration is free to install. However, Klaviyo's contact-volume pricing model means that syncing a large HubSpot contact database into Klaviyo could push the subscriber count into a higher pricing tier. Teams should evaluate whether all HubSpot contacts need to exist in Klaviyo, or whether only marketing-eligible contacts should sync.
Both platforms impose API rate limits that affect custom integrations. HubSpot's private app rate limits range from 100 to 190 requests per 10 seconds depending on plan tier. Klaviyo's tiered rate limits enforce per-second and per-minute windows that vary by endpoint.
Source: HubSpot
Third-party tools carry their own costs. Zapier charges by tasks (each synced record counts). Outfunnel charges by connected contacts.
Permissions and Access
Setting up the native integration requires admin access in both HubSpot and Klaviyo. In HubSpot, you need account admin or super admin rights to install marketplace apps and authorize OAuth connections. In Klaviyo, Owner or Admin role access is required to generate API keys and authorize third-party integrations. If either platform uses SSO or IP restrictions, ensure the integration service can authenticate.
Maintenance
Both platforms evolve independently. HubSpot introduced date-based API versioning in March 2026, with versions supported for a minimum of 18 months. Klaviyo follows a documented versioning and deprecation policy with its own revision schedule.
Source: Hubspot
The native integration (maintained by KAV Labs) depends on that developer keeping the app current with both platforms' API changes. Custom fields added after the initial setup will not sync unless the integration configuration is updated. Plan for periodic reviews of the integration's health and accuracy.
What No Method Fixes: The Data Itself
Every method above moves records between HubSpot and Klaviyo. None of them checks whether those records are accurate, complete, or current. A contact with a stale email address in HubSpot syncs as a contact with a stale email address in Klaviyo. A profile with missing company attributes travels just as reliably as a clean one. The integration ensures both systems agree; it does not ensure they are right.
Where ZoomInfo Fits In
Every method in this guide moves data between HubSpot and Klaviyo. None of them improves the data being moved. When the integration is live but marketing campaigns bounce because email addresses are outdated, or sales reps waste calls on contacts who changed jobs two quarters ago, the bottleneck is no longer the connector.
That is the gap ZoomInfo closes.
ZoomInfo is an AI go-to-market platform built on 500M contacts, 100M companies, 135M+ verified phone numbers, and 200M+ verified business email addresses. For teams running a HubSpot-Klaviyo integration, ZoomInfo addresses the data quality layer that no connector handles.
Source: ZoomInfo
ZoomInfo integrates natively with HubSpot through the ZoomInfo Inbound Enrich app, providing automatic contact and company data enrichment within HubSpot. Contacts entering HubSpot through forms, imports, or manual entry are enriched with verified emails, direct dials, job titles, company attributes, and technographics in real time.
Source: ZoomInfo
That enriched data then flows through whatever HubSpot-Klaviyo connector the team has chosen, so Klaviyo campaigns target contacts with accurate, current information.
For Klaviyo specifically, ZoomInfo's Enterprise API and MCP server can push enriched data into any system through custom integrations or workflow automation tools.
Source: ZoomInfo
The same data feeds ZoomInfo's GTM Context Graph, which processes 1.5B+ data points daily by combining ZoomInfo's B2B data with your CRM records, conversation transcripts, and behavioral signals to surface not just what happened in a deal, but why.
Source: ZoomInfo
In practice, a team running both platforms can use ZoomInfo to enrich records in HubSpot (where the native integration handles it automatically), then sync those enriched records to Klaviyo through the Klaviyo for HubSpot connector.
The result: Klaviyo email campaigns reach verified inboxes, SMS flows target accurate phone numbers, and segmentation in Klaviyo reflects current job titles, company sizes, and industries rather than data that decayed months ago.
Buyer Intent data from ZoomInfo, tracking signals from 210 million IP-to-Organization pairings, can be routed into HubSpot to prioritize accounts actively researching relevant solutions, and that prioritization carries through to Klaviyo campaigns.
Source: ZoomInfo
Enriched records also make the integration itself more reliable. Fewer blank fields mean fewer mismatches during deduplication. Consistent formatting across records reduces the false positives that create duplicates. And intent signals help teams decide which records need to exist in both systems, rather than syncing everything indiscriminately.
Seismic's sales team attributed 39% of active pipeline to opportunities identified or influenced by ZoomInfo signals, while boosting productivity by 54% and saving 11.5 hours per week. (Seismic)
Final Verdict
A native HubSpot-Klaviyo integration exists, supplemented by third-party tools and custom API options. For most teams, the right choice depends on data complexity and how deeply the two platforms need to interact.
Small teams syncing contacts and engagement data between HubSpot and Klaviyo should start with the native Klaviyo for HubSpot integration. It is free, bidirectional, and requires no engineering resources.
Teams that need event-driven workflows (triggering Klaviyo flows based on HubSpot deal stages, or syncing specific form submissions with conditional logic) should add Zapier on top of the native integration to handle the scenarios it does not cover.
Sales teams that need Klaviyo email engagement data visible inside HubSpot contact timelines should evaluate Outfunnel for its marketing-to-CRM data flow.
Organizations with complex data models, custom objects, or business logic that must be enforced during sync should invest in a custom API integration.
Before committing to a method, clarify why both platforms need to coexist.
If the answer is temporary (a migration in progress, a team evaluating whether to consolidate), keep the sync simple and plan for eventual consolidation. If the answer is structural (HubSpot serves the B2B sales motion while Klaviyo powers B2C email and SMS marketing, and both are staying), invest in a method that supports bidirectional sync and handles the data model differences between the two platforms.
Either way, the quality of the data in both systems determines whether the integration delivers value or just replicates problems at twice the speed.
ZoomInfo, with its native HubSpot integration and API and MCP access, is the data enrichment layer that keeps both systems accurate while the connector keeps them aligned.
FAQ
Does a native HubSpot-Klaviyo integration exist?
Yes. Klaviyo for HubSpot (by KAV Labs) is available in the HubSpot App Marketplace and provides bidirectional sync of contacts and marketing engagement data. The integration is free to install and does not require a paid tier on either platform beyond the base subscriptions. Additional integrations are available through Outfunnel and Zapier for use cases the native connector does not cover.
What data syncs between HubSpot and Klaviyo?
The native integration syncs contact records (name, email, phone, custom properties), list and segment memberships, lifecycle stages, and marketing engagement data (email opens, clicks, unsubscribes). Deals, tickets, and custom objects in HubSpot do not sync through the native integration. To sync those, use Zapier or a custom API integration.
Can I sync HubSpot deal data into Klaviyo?
Not through the native integration. Deal data (stage, value, close date) requires either a Zapier Zap that triggers on deal stage changes and pushes the data to Klaviyo as a custom event or profile property, or a custom API integration that maps HubSpot deal objects to Klaviyo events. Once deal data reaches Klaviyo, it can trigger automated flows (e.g., a post-purchase sequence when a deal closes won).
Will syncing my HubSpot contacts to Klaviyo increase my Klaviyo bill?
Potentially. Klaviyo's pricing scales with the number of active profiles. If your HubSpot database contains thousands of contacts not currently in Klaviyo, syncing them will increase your Klaviyo active profile count, which may push you into a higher pricing tier. Configure the integration to sync only marketing-eligible contacts rather than the entire HubSpot database to control costs.
How do I avoid duplicate contacts when syncing?
Use email address as the matching key. Both platforms identify contacts primarily by email. The native integration matches records by email to prevent duplicates. For Zapier, add a "Find Profile" step in Klaviyo before creating a new one, and use HubSpot's search step before creating a new contact. Custom API integrations should use upsert logic on both sides.
Can Klaviyo email engagement data appear in HubSpot?
Yes. The native integration can push Klaviyo engagement data (opens, clicks, unsubscribes) into HubSpot contact records. Outfunnel also handles this use case, making Klaviyo campaign engagement visible on HubSpot contact timelines so sales reps can see which emails a prospect interacted with before making outreach calls.
What permissions are needed to set up the integration?
Admin access in both platforms. In HubSpot, you need account admin or super admin rights to install apps from the marketplace. In Klaviyo, Owner or Admin role access is required to authorize third-party integrations. For custom API integrations, you also need the ability to create private apps (HubSpot) and generate API keys (Klaviyo).
How does ZoomInfo improve a HubSpot-Klaviyo integration?
ZoomInfo solves the data quality problem that no sync tool addresses. Contact records decay over time as people change jobs, email addresses go inactive, and company details shift. ZoomInfo enriches HubSpot records with verified contact data, company attributes, technographics, and intent signals through its native HubSpot integration.
When those enriched records sync to Klaviyo, email campaigns reach real inboxes, SMS flows target accurate phone numbers, and segmentation reflects current information. The data flowing between both systems stays accurate and complete, reducing bounce rates, improving campaign performance, and eliminating noise from stale records.
