Act-On vs. HubSpot (vs. ZoomInfo): How Do They Compare in 2026?

Choosing between Act-On and HubSpot for marketing automation comes down to five questions:

• Do you need a focused marketing automation platform, or a full customer platform spanning sales, service, and content?

• Is your marketing team small enough that ease of use matters more than breadth of features?

• Are you willing to pay for sales and service capabilities you may not use, or would you rather invest in marketing-specific depth?

• How important is it that your platform integrates with your CRM without becoming your CRM?

• Does your team have the B2B data foundation it needs to make either platform work?

In short, here's what we recommend:

Act-On serves mid-market B2B marketing teams that want automation without the complexity of managing a full customer platform. Its Active Contact pricing charges only for the contacts you actually email, not your full database, which can mean real savings for companies with large but segmented contact lists. Act-On's strengths in email deliverability (it runs its own SMTP servers), lead scoring, and multichannel automation make it a solid choice for teams focused on lead generation and nurturing. However, Act-On lacks native CRM, sales, or service tools, its interface is being overhauled slowly, and its starting price of $900/month puts it in mid-market territory.

HubSpot is the all-in-one customer platform for companies that want marketing, sales, service, content, and data management under one roof. With 288,706 customers and a Smart CRM connecting every hub, HubSpot removes the friction of stitching separate tools together. Its Breeze AI layer automates tasks across marketing, sales, and service, and its free CRM tier provides a real onramp. The trade-off is pricing complexity: a per-seat, per-hub model with mandatory onboarding fees at Professional and Enterprise tiers, and a rule where all Core Seats are billed at the rate of your highest subscription tier when mixing hubs.

Both platforms give you the tools to execute campaigns. But campaigns are only as good as the data behind them. The contacts you're targeting, the signals telling you when to reach out, the intelligence showing you which accounts are in-market: that's the layer neither Act-On nor HubSpot was built to provide on its own.

ZoomInfo is an AI-powered GTM platform that lets your sales reps walk into every call knowing why the deal is moving, who's championing it, and what's likely to happen next. Your marketers can describe audiences in plain language and launch plays against the accounts that match your proven win patterns. No engineering ticket required. Your leaders can see deal risk before it shows up in CRM stage fields. That depth comes from the GTM Context Graph, built on a B2B dataset of 500M contacts, 100M companies, 135M+ verified phone numbers, and 200M+ verified business emails, unified with your CRM records, conversation transcripts, and behavioral signals. Your team accesses it through GTM Workspace for sellers, GTM Studio for marketers and RevOps, or APIs and MCP in any front-end. ZoomInfo integrates directly with both Act-On and HubSpot, feeding verified contacts, intent signals, and account intelligence into whichever platform your team runs campaigns from.

If building your campaigns on comprehensive B2B data sounds like the missing piece, see how ZoomInfo works with your existing stack.

Act-On vs. HubSpot vs. ZoomInfo at a glance

Marketing automation: focused vs. all-in-one

This is the fundamental fork. Act-On does one thing: marketing automation. HubSpot does marketing automation plus sales, service, content management, data operations, and commerce.

Act-On concentrates its development effort on the marketing workflow. Its Automated Journey Builder lets marketers design multi-step campaigns with email, SMS, branching logic, and wait steps. The email composer offers drag-and-drop design with dynamic content blocks that change based on contact attributes. A/B testing supports up to five email variants, and Adaptive Send delivers emails when each contact is most likely to engage, using behavioral data going back 25 months.

Source: Act-On

Where Act-On stands out is email deliverability. Unlike most competitors that rely on third-party SMTP providers, Act-On maintains its own SMTP servers, giving it direct control over inbox placement. The company also offers Email Deliverability Services for organizations where email reputation is business-critical.

Source: Act-On

HubSpot's Marketing Hub covers similar ground (email, landing pages, forms, automation workflows, social media management) but sits inside a broader platform. The advantage: marketing data flows directly into Sales Hub and Service Hub without integration work. A lead captured on a landing page is immediately visible to sales reps, complete with every page visit, email open, and form submission. That shared data layer is HubSpot's core pitch.

Source: HubSpot

HubSpot's marketing automation includes visual workflow builders, audience segmentation powered by CRM data and behavioral signals, and AI-powered personalization (beta) that adjusts landing pages and emails based on visitor attributes. The Breeze Social Agent automates social media publishing, and Content Remix transforms one piece of content into formats for multiple channels.

Source: HubSpot

The question: does your team need marketing automation that integrates with your CRM, or marketing automation that is your CRM? Act-On excels at the former. HubSpot is built for the latter.

The data gap neither marketing platform fills on its own

Here's what most Act-On vs. HubSpot comparisons leave out: both platforms assume you already have good data.

Act-On automates campaigns to contacts in your database. HubSpot manages relationships with contacts in its CRM. But neither tells you which companies in your total addressable market are actively researching solutions like yours right now. Neither verifies that the email addresses in your database are still accurate. Neither identifies the full buying committee at a target account or surfaces that a decision-maker just changed jobs.

This is where ZoomInfo fills the gap. The platform provides:

• Verified contact data (500M contacts, 200M+ verified business emails, 135M+ verified phone numbers) so your campaigns reach real people at real companies

• Buyer intent signals showing which accounts are actively researching topics related to your solution, through 6 trillion+ keyword-to-device pairings sourced monthly

• Website visitor identification (WebSights) that resolves anonymous traffic to companies, including buying team members and their direct contact information

• Technographic data profiling the tech stacks of 30+ million companies across 30,000+ technologies, so you know which prospects use complementary or competing tools

• Account-level intelligence including org charts, department structures, and company attributes across 300+ data points

The practical impact: a marketing team running Act-On or HubSpot with ZoomInfo data can target verified decision-makers at accounts showing active buying intent, rather than guessing which contacts in a stale database might be interested. Snowflake achieved 90% higher opportunity open rates and 2x higher customer conversion rates using ZoomInfo-powered account scoring.

ZoomInfo delivers this intelligence through APIs and MCP for any tool, GTM Studio for marketers and RevOps, and GTM Workspace for sellers. The same data foundation powers all three access points, so what your marketing team discovers in GTM Studio is immediately actionable by sellers in GTM Workspace.

Lead scoring and qualification take different approaches

Both Act-On and HubSpot offer lead scoring, but the data powering those scores determines their accuracy.

Act-On provides dual-track scoring: manual rules and AI predictions. The manual system lets teams assign numeric values to specific activities (email opens, page visits, form submissions) and demographic attributes (job title, company size, industry). Teams can create up to 4 additional score sheets beyond the default for different products, regions, or customer segments. The AI Predictive Lead Score uses machine learning trained on contact behaviors and CRM outcomes to predict which leads are most likely to close, updating daily.

Source: Act-On

HubSpot offers Predictive Lead Scoring powered by its Smart CRM, using AI to analyze CRM properties, behavioral events, and engagement data. Because HubSpot's scoring draws on data from marketing, sales, and service interactions (all in one platform), it works with a broader signal set. The Breeze Prospecting Agent extends this by monitoring buying signals and personalizing outreach automatically.

Source: HubSpot

Both scoring systems share a limitation: they can only score what they can see. If your contact database is incomplete (missing decision-makers, outdated job titles, no insight into whether the account is actively researching solutions), the scores rest on partial information.

This is where ZoomInfo changes the equation. ZoomInfo's Buyer Intent data tracks signals from 210 million IP-to-Organization pairings and 6 trillion+ new keyword-to-device pairings sourced monthly to identify which companies are actively researching topics relevant to your product. Guided Intent, exclusive to ZoomInfo, identifies topics historically correlated with your deal success rather than requiring manual topic selection.

When this intent data flows into Act-On or HubSpot through native integrations, your lead scoring models gain a signal they could never generate on their own: external buying behavior happening outside your website and email campaigns.

CRM integration reveals different philosophies

Act-On was designed to work alongside your CRM, not replace it. The platform offers native CRM integrations with Salesforce, Microsoft Dynamics 365, SugarCRM, Oracle NetSuite, and Zendesk Sell, with bidirectional data sync that pushes lead scores, engagement data, and campaign activity into your CRM while pulling contact records and deal data back. Act-On calls these the "industry's BEST CRM integrations", with particularly deep Salesforce connectivity.

Source: Act-On

This separation has a practical upside: your sales team keeps the CRM they already know, and Act-On adds marketing intelligence to it. The downside is that you're maintaining two platforms, and data sync introduces latency and occasional conflicts.

HubSpot is the CRM. Marketing Hub, Sales Hub, and Service Hub all sit on the Smart CRM, sharing one contact record. There's no integration to configure between marketing and sales because they already share the same database. When a marketing-qualified lead is ready for sales, the handoff is instant because sales already has every interaction logged. HubSpot also offers a bidirectional Salesforce sync for teams that need both platforms.

Source: HubSpot

ZoomInfo integrates with both approaches. For Act-On users, ZoomInfo connects to their CRM (Salesforce, Dynamics, etc.) to enrich contact and company records, and those enriched records flow into Act-On through the CRM integration. For HubSpot users, ZoomInfo has a native HubSpot integration that feeds verified contacts, company attributes, and intent signals directly into HubSpot's Smart CRM. In both cases, ZoomInfo fills the data gaps that neither marketing platform creates on its own.

AI capabilities are evolving fast on both sides

Both Act-On and HubSpot have invested in AI, but at different scales and with different ambitions.

Act-On's AI features target specific marketing workflows. Act-On AI Create uses generative AI for email content and subject lines. AI Predictive Lead Score applies machine learning to lead qualification. AI Audience Insights helps identify new segments. InSite web agents deliver personalized website content. These are practical tools that enhance existing workflows.

Source: Act-On

HubSpot's AI ambitions are broader. Breeze runs across the entire platform with specialized agents: the Customer Agent resolves support inquiries autonomously, the Prospecting Agent monitors buying signals and drafts personalized outreach, and the Data Agent answers natural-language questions about CRM data. HubSpot positions itself as "the agentic customer platform", signaling that AI agents will be central to its product strategy. Several features, including AI-Powered Segmentation and Marketing Studio, are still in Beta.

Source: HubSpot

ZoomInfo's AI operates on a different data set. The GTM Context Graph processes 1.5B+ data points daily, fusing ZoomInfo's B2B data with customer CRM records, conversation transcripts, and behavioral signals. It captures why deals move or stall, not just that they did. GTM Workspace uses AI agents (built on Anthropic's Claude) to draft outreach, research accounts, and surface next-best actions. GTM Studio lets marketers describe audiences in natural language and launch multi-channel plays without engineering tickets.

The distinction matters. Act-On and HubSpot AI helps you execute campaigns more efficiently. ZoomInfo AI helps you identify which campaigns to run and which accounts to target.

Analytics and reporting: depth vs. breadth

Act-On offers a tiered analytics platform with three packages: Standard Reporting (included), Dynamic Business Analytics (add-on), and Premium AI Analytics (add-on). The Premium tier includes natural language query processing where marketers type questions in plain language and receive AI-generated reports, plus SpotIQ automated analysis that surfaces trends and outliers. For CRM-integrated accounts, Act-On provides revenue and attribution reports covering pipeline, funnel metrics, and revenue impact. Data retention spans 15 months on Standard, extending to 27 months on Premium.

Source: Act-On

Some users note that out-of-box reports aren't useful without customization.

HubSpot provides Advanced Marketing Reporting with multi-touch revenue attribution and customer journey analytics (called Pathfinder). Because reporting draws on unified data from marketing, sales, and service, HubSpot can show the complete path from first website visit to closed deal.

Source: HubSpot

ZoomInfo adds intelligence that neither platform generates internally. AI-powered dashboards in GTM Studio track engagement, funnel progression, and top-performing segments. More importantly, ZoomInfo can show you which accounts are in-market before they ever interact with your campaigns, a leading indicator that marketing automation analytics alone can't provide.

The pricing math changes depending on what you need

Pricing is where these two platforms diverge sharply, and where the decision often gets made.

Act-On's Active Contact model charges $900/month for 2,500 active contacts on the Professional tier. "Active contacts" means only the contacts you email in a given month, not your total database. If you have 50,000 contacts but only email 5,000 regularly, you pay for 5,000. The Enterprise tier adds native CRM integrations, Data Studio, and account-based marketing at custom pricing. Both tiers require annual contracts with automatic 5% increases on renewal unless you negotiate otherwise.

HubSpot uses a layered pricing structure that rewards platform consolidation but punishes selective adoption. Marketing Hub Professional starts at $800/month (annual) with 2,000 marketing contacts and 3 Core Seats included, plus a $3,000 onboarding fee. Marketing Hub Enterprise is $3,600/month with 10,000 contacts and a $7,000 onboarding fee. Additional marketing contacts are billed immediately when you exceed your tier.

Where HubSpot pricing gets complicated is the multi-hub scenario. If you subscribe to Marketing Hub Professional and Sales Hub Enterprise, all Core Seats are billed at the Enterprise rate (the highest tier you hold). This can add thousands per month in unexpected seat costs. The Starter Customer Platform at $15/seat/month bundles entry-level versions of all hubs, but teams needing Professional-tier marketing automation will quickly outgrow it.

HubSpot's free CRM tier is useful for getting started (unlimited contacts, basic email, forms, and live chat), and there's no time limit. But the jump from free to Professional is steep.

ZoomInfo uses custom-quoted pricing based on seats, credits, and features. No published prices, but ZoomInfo Lite offers a permanent free tier with access to the B2B database, 10 monthly export credits, and basic prospecting tools. The credit model (1 credit = 1 contact or company export) means you pay for the data you pull, not for a static subscription to features you may not use.

Support and onboarding reflect different customer bases

Act-On is consistently praised for customer support. Users describe it as "some of the best support they've had for a SaaS offering" and highlight the "personalized attention and emphasis on creating a true partnership." The Professional tier includes Standard support with email-based support, with Premium and Premium+ programs available for faster response times, office hours, and deliverability consulting. Some reviewers note that customer experience reps may be too busy to provide in-depth strategy support.

HubSpot tiers its support by subscription level. Free users get community support only. Starter adds email and chat. Professional and Enterprise include phone support. Beyond direct support, HubSpot Academy offers free certifications (over 200,000 professionals certified) and a large Solutions Partner network for implementation.

ZoomInfo provides support through a Help Center, ZoomInfo University with role-specific learning paths, and direct phone support. The company redesigned its onboarding program from 30 to 90 days and achieved a 25% improvement in customer satisfaction scores, winning Rocketlane's Golden Comet award for Best Customer Onboarding Team of 2024.

Act-On vs. HubSpot vs. ZoomInfo: Which should you choose?

These three platforms solve different problems. The right choice depends on which problem is most pressing.

Choose Act-On if:

• Marketing automation is your primary need, and your CRM is already established

• Your team values focused depth over platform breadth

• The Active Contact pricing model saves you money compared to database-size pricing

• You need strong email deliverability with dedicated SMTP infrastructure

• Your marketing team operates independently from sales tooling

• You work in a regulated industry where HIPAA compliance matters

Choose HubSpot if:

• You want marketing, sales, and service on a single platform with shared data

• You're replacing a fragmented stack of point solutions with one connected system

• Ease of use and fast time-to-value matter more than feature depth in any one area

• Your team is ready to commit to HubSpot as the central system for go-to-market

• You want a free CRM to start with and the ability to scale into paid tiers

Add ZoomInfo to either if:

• Your campaigns need better data: verified contacts, direct dials, and accurate emails

• You want to identify in-market accounts before they fill out a form or visit your website

• Your lead scoring would benefit from external intent signals, not just internal engagement data

• Your sales team needs account intelligence and buying committee mapping

• You're building an AI-powered GTM motion and need the data foundation to make it work

See how ZoomInfo powers your go-to-market stack.

Act-On vs. HubSpot is a question about how you execute campaigns. ZoomInfo answers the question that comes before execution: who should you target, and when? The most effective go-to-market teams don't choose between execution and intelligence. They layer ZoomInfo's data and GTM Context Graph underneath whichever execution platform fits their workflow, so every campaign starts with the best data available.

Act-On vs. HubSpot vs. ZoomInfo FAQ

What is the fundamental difference between Act-On, HubSpot, and ZoomInfo?

Act-On is a dedicated marketing automation platform focused on email campaigns, lead scoring, and multichannel nurturing for mid-market B2B teams. HubSpot is an all-in-one customer platform combining marketing, sales, service, content, and data management on a shared CRM. ZoomInfo is a B2B data and GTM intelligence platform that provides verified contacts, intent signals, and account intelligence to power campaigns in either Act-On or HubSpot.

Which is cheaper: Act-On or HubSpot?

It depends on what you need. Act-On starts at $900/month for 2,500 active contacts, charging only for contacts you actually email. HubSpot Marketing Hub Professional starts at $800/month (annual) for 2,000 marketing contacts plus a $3,000 mandatory onboarding fee. However, HubSpot includes a free CRM tier and offers a Starter plan at $15/seat/month. Act-On requires annual contracts with automatic 5% renewal increases. HubSpot's costs escalate when mixing hub tiers, since all Core Seats are billed at the rate of the highest tier.

Do I need ZoomInfo if I already use Act-On or HubSpot?

Act-On and HubSpot execute campaigns. ZoomInfo provides the data foundation those campaigns depend on: verified contact information, buying intent signals, technographic data, and account intelligence. Neither Act-On nor HubSpot maintains a B2B contact database at ZoomInfo's scale (500M contacts, 200M+ verified emails), nor do they offer intent data showing which accounts are actively researching solutions like yours. ZoomInfo integrates natively with both platforms.

Which platform is better for lead scoring?

Act-On offers manual rule-based scoring plus AI Predictive Lead Score updated daily. HubSpot provides Predictive Lead Scoring powered by its unified CRM data across marketing, sales, and service interactions. Both platforms score based on internal data (email engagement, form submissions, page visits). ZoomInfo adds external signals (including buyer intent data from 210 million IP-to-Organization pairings) that neither platform can generate on its own. When ZoomInfo intent data flows into Act-On or HubSpot scoring models, accuracy improves because the score reflects external buying behavior, not just internal engagement.

Which platform has better AI capabilities?

HubSpot's Breeze AI is the broadest, spanning content creation, prospecting, customer service, and data management across the full platform. Act-On's AI is more targeted: email content generation, predictive lead scoring, and analytics. ZoomInfo's GTM Context Graph processes 1.5B+ data points daily and captures why deals move or stall, powering AI agents in GTM Workspace and GTM Studio. Each serves a different purpose: Act-On and HubSpot AI helps execute marketing tasks more efficiently, while ZoomInfo AI identifies which accounts and contacts to focus on.

How does CRM integration work with each platform?

Act-On integrates with external CRMs (Salesforce, Dynamics, SugarCRM, NetSuite, Zendesk Sell) through bidirectional data sync. HubSpot includes its own Smart CRM natively and also offers bidirectional Salesforce sync. ZoomInfo integrates with all major CRMs and both Act-On and HubSpot, feeding verified contact data, company attributes, and intent signals into whichever system your team uses.

Which platform works best for account-based marketing?

ZoomInfo's Marketing product includes a native ABM platform with cross-channel advertising, contact-level site visitor identification, and AI-powered account fit scoring. HubSpot supports ABM through its Marketing Hub with account targeting and reporting, though it lacks native intent data at ZoomInfo's depth. Act-On offers ABM capabilities as an Enterprise tier add-on, with account-level insights and sales dashboards. For the most comprehensive ABM approach, teams pair ZoomInfo's account intelligence and intent data with Act-On or HubSpot's campaign execution.

Is Act-On or HubSpot easier to learn?

HubSpot is generally considered easier to start with, thanks to its free tier, intuitive interface, and extensive HubSpot Academy courses. Act-On rates above the marketing automation average for ease of use on review platforms and is praised for drag-and-drop email design and straightforward campaign setup. Both have steeper learning curves at advanced levels (complex automation workflows, custom analytics).
