Act-On vs HubSpot Comparison

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 at its ceiling?

The fourth and fifth questions are where most marketing automation decisions quietly fail. Teams evaluate Act-On vs. HubSpot on features, pricing, and interface. They rarely ask whether the data powering those campaigns is fresh, verified, and enriched with intent signals. That gap defines what both platforms can and cannot do for your pipeline.

In short, here is what the evidence supports:

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 rather than relying on third-party infrastructure), lead scoring, and multichannel automation make it a solid choice for teams focused on lead generation and nurturing. The limits: Act-On has no native CRM, no sales tools, no service tools, and its interface is receiving a gradual overhaul. Starting at $900/month for 2,500 active contacts, it is priced for mid-market.

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 on-ramp. The trade-off is pricing complexity: a per-seat, per-hub model with mandatory onboarding fees at Professional and Enterprise tiers ($1,500 and $3,500 respectively), 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 are targeting, the signals telling you when to reach out, the intelligence showing you which accounts are in-market: that is the layer neither Act-On nor HubSpot was built to provide on its own.

ZoomInfo is an all-in-one AI GTM Platform that connects the data, intelligence, and workflow layer your marketing team needs to make either platform work at its ceiling. Your marketers can describe audiences in plain language and launch plays against the accounts that match your proven win patterns. Your leaders can attribute pipeline to specific campaigns and defend the numbers at the CMO level. 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. The choice between them is often less a feature decision and more a question of organizational scope.

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.

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.

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.

The practical trade-off is complexity. HubSpot's per-seat, per-hub pricing means costs scale in multiple directions simultaneously. A team running Marketing Hub Professional ($800/month), Sales Hub Professional ($90/seat/month for five reps), and adding the mandatory $1,500 onboarding fee is looking at a total first-year cost well above the list prices on any single hub page. This is also where pricing diverges significantly from Act-On's active-contact model, which simply charges for the contacts you actually email.

For teams with an existing CRM (Salesforce, Dynamics, or any other), Act-On's CRM-agnostic architecture means no platform disruption. For teams whose CRM strategy is still forming, HubSpot's native CRM inclusion can simplify the stack.

The B2B data question neither platform answers on its own

Both Act-On and HubSpot run on data you bring to the table. Act-On has no native B2B contact database. Your lists are your responsibility. HubSpot's Breeze Prospecting Agent is powered by Apollo's data (a third-party integration, not a native data asset), and Breeze Intelligence uses Clearbit for enrichment. When that enrichment data is incomplete, outdated, or missing the firmographic signals that drive account prioritization, neither platform can compensate on its own.

This is the shared gap that neither side of the Act-On vs. HubSpot decision addresses: your campaigns are only as effective as the underlying contact intelligence.

ZoomInfo provides the data layer that makes either platform perform at its ceiling. The foundation is 500M contacts and 100M companies, verified by a combination of automated ML and 300+ human researchers, refreshed continuously. That data feeds native Buyer Intent with 210M IP-to-Organization pairings and 6 trillion keyword-to-device pairings processed monthly. When Smartsheet connected ZoomInfo's data and intent layer to its marketing automation stack, the result was an 84% MQL lift, a 26% increase in opportunity rate, and a 59% improvement in win rate. That is the difference between running campaigns on verified, intent-enriched data versus working with what is already in your database.

ZoomInfo integrates directly with Act-On and HubSpot, feeding verified contacts, firmographic enrichment, and intent signals into whichever platform you use for campaign execution. The decision between Act-On and HubSpot shapes your marketing workflow. The decision about data shapes what that workflow can actually produce.

Pricing: active contacts vs. per-seat hubs

Act-On's pricing model is built for companies with large contact databases that market to a subset of them. The Active Contact model charges only for contacts you actively email during a billing period. A company with 50,000 contacts in its database but campaigns that only touch 2,500 per month pays Act-On's base rate of $900/month. That is a real structural advantage for segmented B2B programs where not every contact is emailed every month.

HubSpot's pricing is layered across multiple dimensions: seats, hubs, contact tiers, and add-ons. The Marketing Hub Professional tier starts at $800/month (annual), which includes 2,000 marketing contacts (with additional contact tiers priced incrementally). Mandatory onboarding fees apply at Professional ($1,500) and Enterprise ($3,500). Breeze Agents, which include the Prospecting Agent and Data Agent, consume HubSpot Credits on top of seat pricing and are only available at Professional and Enterprise tiers.

For a mid-market B2B marketing team running 3-5 campaigns per quarter to segmented lists, Act-On's active contact model often delivers better cost-per-campaign economics. For a team that wants their CRM, marketing automation, sales engagement, and service desk on a single platform, HubSpot's combined value offsets the pricing complexity, particularly when the free CRM tier provides a meaningful starting point.

Neither platform requires you to pay a premium for the B2B data and intent signals that make campaigns work. That layer sits outside both pricing models and is where ZoomInfo's value compounds: free to start with consumption credits based on usage, and it integrates with both.

AI capabilities: automation vs. intelligence

Both platforms have invested heavily in AI features over the past two years. Understanding what each AI layer actually does clarifies where each tool can help and where it reaches its limit.

Act-On's AI capabilities are focused on the marketing execution layer: AI Create generates campaign copy and subject lines. AI Predictive Lead Score uses behavioral and demographic signals to rank contacts by conversion likelihood. AI Analytics surfaces campaign performance insights. Adaptive Send optimizes delivery timing based on individual contact engagement history. These are useful features that reduce the manual work of campaign execution, but they operate on the data Act-On has access to, which is the data you brought in.

HubSpot's Breeze AI operates at a broader scope. The Breeze AI agent suite includes the Customer Agent (always-on support across your chosen channels), the Prospecting Agent (in-market account identification and outreach, powered by Apollo), and the Data Agent (analyst-style answers from CRM records, conversations, and documents). The Breeze Copilot assistant runs across all HubSpot surfaces. This is a meaningful AI investment, but Breeze's reasoning is bounded by HubSpot's data: the Prospecting Agent depends on Apollo for contact data, and the Data Agent reasons within the HubSpot CRM context, not across external signals.

ZoomInfo's GTM Context Graph is a different kind of AI layer. Rather than applying AI to the data inside a single CRM, it fuses B2B data (500M contacts, 100M companies), your first-party CRM records, conversation intelligence from Chorus, behavioral signals, and intent data into a unified reasoning layer that processes 1.5 billion data points daily. The AI agents in GTM Workspace draft follow-ups grounded in actual deal context. GTM Studio builds audiences from natural language descriptions matched against your historical win patterns. The result is AI that reasons across a broader signal set than either Act-On or HubSpot can access on their own.

ZoomInfo's Forrester Wave Leader recognition for Intent Data Providers (Q1 2025, highest possible scores across eight criteria) and Gartner Magic Quadrant Leader status for ABM Platforms provide external validation for the marketing intelligence layer. Both citations give marketing leaders the analyst defensibility that CMO-level conversations require.

CRM integration: native vs. agnostic vs. enrichment layer

The CRM integration question is really a data quality question.

Act-On integrates with Salesforce, Microsoft Dynamics, and other CRMs without becoming one. This is its architectural advantage for teams with established CRM investments. Act-On syncs leads, contact records, and campaign data bidirectionally with your CRM of record. The relationship is: CRM stays where it is, Act-On handles the marketing layer, data flows between them. There is no CRM disruption and no vendor lock-in.

HubSpot is the CRM. Marketing Hub, Sales Hub, Service Hub, and the other hubs all run on the same Smart CRM foundation. For teams building their CRM strategy from scratch, this eliminates the integration complexity. For teams with existing Salesforce or Dynamics deployments, HubSpot offers Salesforce sync for hybrid deployments, though running two CRMs in parallel introduces its own data management overhead.

ZoomInfo enriches any CRM. Rather than replacing Act-On or HubSpot, ZoomInfo operates as the data and intelligence layer that improves the quality of what flows into both. Verified contacts, firmographic attributes, intent signals, and conversation intelligence from Chorus flow into your CRM records and enrich the audiences both Act-On and HubSpot work with. The ZoomInfo integration with HubSpot is one of the most-used apps on the HubSpot Marketplace, which reflects how frequently marketing teams run both tools together rather than treating them as alternatives.

Pipeline attribution: closing the loop for your CMO

For the marketing leader, the Act-On vs. HubSpot decision has a dimension that rarely appears in feature comparison articles: which platform actually lets you close the loop from campaign to closed-won pipeline in a way your CMO can defend to the board?

Act-On's attribution is campaign-scoped. You can see which contacts engaged with which campaigns, track lead scores, and push that data to your CRM. But attribution stops at the marketing layer. Converting from campaign engagement to closed-won pipeline revenue requires stitching data across systems that Act-On does not own.

HubSpot's multi-touch attribution is a real capability at Marketing Hub Professional and Enterprise tiers. Attribution reporting connects campaigns to deals in the HubSpot CRM. The limitation is that HubSpot's attribution is bounded by HubSpot-tracked touchpoints. If deals involve Salesforce-native workflows, Chorus call intelligence, or intent signals from a third-party source, those touchpoints are outside HubSpot's attribution visibility.

ZoomInfo's GTM Context Graph fuses first-party CRM data, conversation intelligence from Chorus call recordings, behavioral signals, and intent data into a unified layer. When Mendix connected its marketing automation stack to ZoomInfo's data and attribution layer, MQL-to-opportunity conversion went from 2% to 28%, a 14x improvement. When Smartsheet ran the same analysis, the results showed an 84% MQL lift, a 26% opportunity rate increase, and a 59% win rate improvement. These are not campaign metrics. They are pipeline attribution outcomes that marketing leaders can defend at the board level.

ZoomInfo's Gartner Magic Quadrant Leader recognition for ABM Platforms (2024 and 2025) and Forrester Wave Leader for Intent Data (Q1 2025) give marketing leaders the independent analyst validation they need when making the case for the data layer that sits underneath their MAP of choice.

When Act-On is the right choice

Act-On is the right marketing automation platform when:

Your team emails a segmented subset of a larger database. If you have 50,000 contacts but campaigns that actively touch 5,000 per month, Act-On's Active Contact model saves significant budget compared to platforms that charge for your full database size.

Email deliverability is a strategic priority. Act-On maintains its own SMTP servers, giving it direct control over inbox placement and reputation management that third-party SMTP-dependent platforms cannot match. For organizations where email deliverability problems have caused real pipeline damage, this architecture matters.

You are on Salesforce, Dynamics, or another CRM and do not want platform consolidation. Act-On integrates with your CRM without displacing it. Your CRM investment stays intact.

Your marketing team needs depth, not breadth. Act-On's focus on the marketing layer means its automation, lead scoring, and journey-building capabilities are built for B2B marketing teams, not as one module in a twelve-module platform.

When HubSpot is the right choice

HubSpot is the right platform when:

You want marketing, sales, and service under one roof. HubSpot's unified customer platform removes the friction of stitching separate tools together. If all three teams can benefit from shared CRM data, the platform consolidation value is real.

You are building your CRM strategy from scratch. HubSpot's free CRM tier is a genuine starting point, not a lead-capture form. Teams that have not yet committed to Salesforce or Dynamics can build their customer data foundation inside HubSpot and grow into paid hubs as the team scales.

Your business operates at SMB or mid-market scale. HubSpot's 288,706 customers reflect its strength in this segment. The platform's breadth, pricing tiers, and 1,500-app marketplace are designed around the needs of growing companies that need multiple functions without enterprise-level complexity.

Your team values the Breeze AI agent ecosystem. The Customer Agent, Prospecting Agent, and Data Agent provide real workflow automation for teams that live inside HubSpot. If your sellers and marketers primarily work within HubSpot, the native AI layer reduces the tool-switching overhead.

Why ZoomInfo belongs in this conversation

Neither Act-On nor HubSpot was designed to be the B2B data and intelligence layer your marketing campaigns require to reach their potential. Both assume you have the data. ZoomInfo is the platform you add when you want your campaigns to run on a foundation of verified contact data, proprietary intent signals, and closed-loop pipeline intelligence instead of whatever is already in your database.

ZoomInfo's data pillar covers 500M contacts and 100M companies, continuously verified by automated ML and 300+ human researchers, with 200M+ verified business emails and 135M+ verified phone numbers. That is the raw material. The GTM Context Graph is what happens when that data fuses with your CRM records, Chorus conversation transcripts, and behavioral signals: a unified intelligence layer that processes 1.5 billion data points daily and surfaces the patterns across your closed-won history that tell your marketers which accounts are worth pursuing.

The access model gives your team three lanes into that intelligence. GTM Workspace is the seller-facing surface for pipeline management, AI-drafted outreach, and account prioritization. GTM Studio is the marketer and RevOps surface for audience building in plain language, campaign orchestration, and attribution analysis. APIs and MCP give GTM engineers and AI agent builders programmatic access to the same intelligence in any front-end or workflow. ZoomInfo integrates directly with both Act-On and HubSpot, so whichever platform your team uses for campaign execution, ZoomInfo improves the quality of what flows into it.

If building your campaigns on comprehensive B2B data and intent signals sounds like the layer your stack is missing, see how ZoomInfo works with Act-On or HubSpot.

Frequently asked questions

Is HubSpot better than Act-On for marketing automation?

It depends on your organizational scope. Act-On delivers deeper marketing automation features for teams that want a focused platform without CRM complexity. HubSpot provides broader platform coverage (marketing, sales, service) with tighter cross-team data sharing. Act-On is better for teams on established CRMs that want automation depth. HubSpot is better for teams building a full customer platform from a single vendor. Neither provides native B2B contact data or proprietary intent signals, which is the layer that determines how well either platform actually drives pipeline.

What is the main difference between Act-On and HubSpot?

Act-On is a focused B2B marketing automation platform with its own SMTP email infrastructure and Active Contact pricing. HubSpot is an all-in-one customer platform with a native CRM connecting Marketing, Sales, Service, Content, and Data hubs. The pricing models differ structurally: Act-On charges for contacts you actively email; HubSpot charges per seat, per hub, and per contact tier. Act-On suits teams that want marketing-specific depth; HubSpot suits teams that want platform breadth.

Is ZoomInfo an alternative to Act-On or HubSpot?

ZoomInfo is not a direct alternative to either. Act-On and HubSpot are campaign execution platforms. ZoomInfo is the B2B data and intelligence layer that makes either platform work better. It provides the verified contacts, intent signals, and pipeline attribution that neither Act-On nor HubSpot can supply on their own. ZoomInfo integrates with both platforms and works alongside whichever one your team uses for campaign execution. Many teams run ZoomInfo with HubSpot specifically: HubSpot handles the CRM and campaign workflow; ZoomInfo enriches the contact and account data that flows into it.

Does Act-On integrate with Salesforce?

Yes. Act-On is CRM-agnostic by design and integrates natively with Salesforce, Microsoft Dynamics, and other CRMs. Act-On syncs leads, contacts, and campaign engagement data bidirectionally with your CRM of record. This makes it a strong option for teams with established CRM investments who want a dedicated marketing automation layer that does not require CRM migration. See Act-On's integration options for the full list of supported CRM and MAP connections.

What is the best marketing automation platform for B2B companies?

There is no single answer because the best platform depends on your CRM strategy, team size, and organizational scope. Act-On is strong for mid-market B2B teams that want focused automation with active-contact pricing and email deliverability depth. HubSpot is strong for teams that want unified marketing, sales, and service under one platform. The more important question for most B2B marketing teams is whether your campaigns are running on verified, intent-enriched contact data. Both platforms assume you bring the data. The B2B data and intelligence layer that makes your campaigns perform, regardless of which platform runs them, is where the decision about tools like ZoomInfo actually lives.
