For Act-On vs HubSpot vs Pardot vs Marketo B2B marketing automation, the choice turns on three things each vendor documents: the CRM the platform needs, the contact it bills on, and how a contact becomes a CRM record. Pardot, now Salesforce Marketing Cloud Account Engagement, is installed by a Salesforce admin and syncs on the Salesforce record ID. HubSpot is its own CRM and prices Marketing Hub by marketing-contact tier. Marketo Engage keeps its own lead database and matches new leads on email. Act-On bills on the contacts you email in a calendar month and creates a CRM record only when a form or program step tells it to.
Act-On vs HubSpot vs Pardot vs Marketo B2B Marketing Automation: The Short Answer
- Start from the CRM you already run. Account Engagement connects only to Salesforce; for business units purchased after February 11, 2019, "only a Salesforce admin can install and enable Account Engagement." Act-On names five native CRM integrations (Salesforce, Microsoft Dynamics 365, SugarCRM, Oracle NetSuite and Zendesk Sell), and Marketo's pricing page lists "Native CRM Integration (SFDC, MSD & Veeva)". HubSpot is a CRM itself, and its Salesforce integration needs a Professional or Enterprise subscription.
- The four bill on four different units. Act-On counts "Active Contacts", meaning contacts you message in a calendar month. HubSpot sells marketing-contact tiers (2,000 on Professional, 10,000 on Enterprise). Account Engagement includes a block of 10,000 contacts per org (75,000 on Premium+). Marketo's pricing page publishes no prices or contact unit. The Billable-Contact Ledger below lines them up.
- The record path differs more than the feature lists do. Act-On only adds a contact to Salesforce through a form's Push to CRM setting or a Create in CRM step. Account Engagement creates a Salesforce lead when a prospect is assigned. HubSpot syncs every contact to Salesforce unless you set an inclusion segment. Marketo creates one when a campaign runs a Sync Lead to SFDC step. The Record Path Map puts the key, the creation rule, the sync cadence and the reverse path side by side.
- All four use policies restrict purchased and third-party lists. Act-On, Salesforce, Adobe and HubSpot each publish wording against emailing lists people did not opt in to. Before you choose a platform, decide where sourced contacts land and which system is allowed to email them. The CRM-Gravity Test puts that question first.
Why the Ranking Pages Miss the Record Path
The pages that rank for this comparison answer "which platform has which features". The Act-On page in the results compares Act-On with Pardot using research it says was "commissioned by Act-On". Hyperscayle's guide gives choose-when lists for HubSpot, Marketo and Pardot and leaves Act-On out. MarCloud's comparison declares a winner per feature, and The Pedowitz Group compares Marketo with HubSpot and says the choice is "almost always determined by one factor: your CRM." The 6sense roundup of B2B marketing automation platforms lists seven, places 6sense first and does not include Act-On. RevSure's list of ten includes all four and is written by a company that sells the measurement layer named in its title.
Each of those pages is useful for features. None of them traces one record through the platform: which identifier decides two records are the same person, which system creates the CRM record, how fast changes travel, what happens when a record appears in the CRM first, and what the platform bills on. Those five facts decide how much work the platform creates after the contract is signed, so this guide compares only what each vendor's own pages say about them.
A note on price ranges: third-party pages disagree with each other and with the vendors. Pedowitz quotes Marketing Hub Professional at "$800-$3,200/month depending on contact volume"; HubSpot's page shows a starting figure with 2,000 marketing contacts included. Use the vendor's page and a written quote at your own contact count.
Decision Framework: The CRM-Gravity Test
The workflow behind every B2B automation choice has five stages: source data, enrichment, routing, human-approved outreach and CRM. A contact is found or imported, gains firmographic detail, is assigned to an owner, receives a message a person has approved, and ends up as a lead or contact that sales reads. A marketing automation platform sits in the middle three stages. The CRM pulls it toward one design or another, which is why the test starts there.
The CRM-Gravity Test asks three questions in order. Stop at the first one that removes a platform.
- Which system owns accounts and opportunities for the next contract term? If it is Salesforce, all four connect, and Account Engagement is the one installed inside the Salesforce org. If it is Microsoft Dynamics 365, Act-On and Marketo name it among their native integrations; Account Engagement's connector is Salesforce only. If you run no separate CRM, HubSpot provides one, while Act-On and Marketo keep their own contact databases.
- What will you be billed on, at your counts? Write down three numbers: records in the database, contacts you email in a typical month, and users who need a seat. Then read each platform's unit in the Billable-Contact Ledger against those numbers and ask for a quote. Act-On's unit counts only the contacts you message in a month, so a large database with small monthly sends fits it differently from a small database you email in full; that follows from the definition, not from a published comparison.
- Who is allowed to create a CRM record, and through which step? Read the "Who creates the CRM record" and "Record appears in Salesforce first" columns of the Record Path Map. Pick the platform whose default matches the rule you want, or budget for the setting that changes it.
Field-level authority, meaning which system wins each value once a record exists, is a separate decision. The Field Authority Table and Sync Budget cover it, including how Account Engagement and Marketo resolve a field conflict. Object-level identity across every entry route is covered by the Match-Key Register and Two-Door Test; run that test on whichever platform you shortlist.
Evidence Tables: Record Path, Billing Unit and List Policy
Rows are alphabetical and there is no ranking. Each cell restates the vendor's own pricing page, help article or policy, linked in Sources. "Not described" means the pages cited are silent on the point, not that the product lacks it. The Salesforce column is used throughout because it is the one CRM all four connect to. Prices and plan details are an October 2026 snapshot.
The Record Path Map
| Platform | CRM it needs | Identity key | Who creates the CRM record | Sync cadence | Record appears in Salesforce first |
|---|---|---|---|---|---|
| Act-On | None required; CRM integration is an add-on on Professional and included on Enterprise | Email: Act-On "uses the prospect's email addresses to ensure no duplicates are created in your CRM" | Only "the Push to CRM setting in Forms or a Create in CRM step in Automated Programs"; that step can "Create new contacts (including duplicates if desired)" and cannot reassign an existing record's owner | Full sync every two weeks with incremental syncs between; other mapped changes push immediately | Not described for new CRM records; contacts deleted in Salesforce are removed from Act-On at the next sync, and Act-On "won't delete contacts in Salesforce" |
| HubSpot Marketing Hub | HubSpot is the CRM; the Salesforce integration needs Professional or Enterprise and a Salesforce edition with API access (not Group Edition) | Email for contacts; domain for companies, except companies created through the API; the Salesforce integration deduplicates companies by associated contacts, not domain | HubSpot contacts sync to Salesforce as leads or contacts by default; "If no inclusion segment is selected, all HubSpot contacts will sync" | Sync triggers plus a check for changes "approximately every 15 minutes" | If set to create HubSpot contacts, one is created or deduplicated "even if the HubSpot contact is not in the inclusion segment" |
| Marketo Engage | None required; own lead database, with native Salesforce, Dynamics and Veeva integration | Email: a form fill or list import updates the existing lead with that email; the REST API upsert defaults to email; existing duplicates are not merged automatically | A Sync Lead to SFDC flow step in a campaign; in a trigger campaign each lead uses at least one API call | Continuous; each sync "pauses for 5 minutes, then starts again"; the first sync "may take hours or even days" | Synced into Marketo if the Salesforce credentials in Marketo can see it; a duplicate created in Salesforce "gets synced into Marketo" |
| Salesforce Account Engagement (Pardot) | Salesforce; installed by a Salesforce admin; syncs with Salesforce Professional Edition and higher | Salesforce CRM ID in both directions; email for imports, forms and records without a CRM ID; multiple prospects with the same email are allowed by default and the setting "can't be turned off" | An assigned prospect with no matching Salesforce record creates a lead; unassigned prospects stay in Account Engagement only | "Syncing occurs every 2–4 minutes" | Account Engagement creates a prospect when the connector user can view the record; Marketing Data Sharing controls which records sync |
Three findings come straight from the map:
- Two of the four create Salesforce records only on an explicit step (Act-On and Marketo). HubSpot creates them for every contact unless an inclusion segment limits the sync, and Account Engagement creates them for every assigned prospect.
- Three of the four pull Salesforce records back automatically (HubSpot when its setting is on, Marketo within the credentials' visibility, Account Engagement within the connector user's visibility). A contact pushed into Salesforce by any source tool can arrive in the automation platform without a marketing step. In those three, the control is a setting or a permission, and it belongs in the build plan.
- Cadence ranges from minutes to a fortnight for a full refresh. Account Engagement documents 2–4 minutes, Marketo a 5-minute pause, HubSpot a check about every 15 minutes, and Act-On a full sync every two weeks with incremental syncs between whose interval its article does not state.
The Billable-Contact Ledger
| Platform | Billing unit | Published entry price | Contacts or seats included | Contract and extras named on the page |
|---|---|---|---|---|
| Act-On | "Active Contacts": "In a calendar month, the first message you send to a contact marks that contact as 'active'"; the count resets monthly | Professional "$900 per month" at the page's default of 2,500 contacts a month; Enterprise custom | Price scales with the Active Contacts slider; at the limit, sends to new contacts stop | Annual contract required; CRM integration an add-on on Professional; price "may vary depending on additional factors – including add-ons, configuration, and implementation" |
| HubSpot Marketing Hub | Marketing-contact tiers plus Core Seats | Professional "Starts at" $800/mo and $890/mo, shown with a monthly-or-annual billing toggle whose mapping is not stated beside the figures; Enterprise "Starts at $3,600/mo" | Professional: 3 Core Seats, 2,000 marketing contacts; Enterprise: 5 Core Seats, 10,000 marketing contacts; extra seats from $45 and $75 a month | One-time onboarding of $3,000 (Professional) and $7,000 (Enterprise) not included in the price shown; monthly email sends capped at 10x (Professional) and 20x (Enterprise) the contact tier |
| Marketo Engage | Not stated on the pricing page | None; every package says "Get pricing" | Growth: 10 users and 20,000 API calls a day; Select, Prime and Ultimate: 25 users and 50,000 calls a day | Four packages (Growth, Select, Prime, Ultimate); prices by quote |
| Salesforce Account Engagement (Pardot) | Price per org, with contact blocks | Growth+ $1,250, Plus+ $2,750, Advanced+ $4,400, Premium+ $15,000 USD per org per month, billed annually | 10,000 contacts on Growth+, Plus+ and Advanced+; 75,000 on Premium+; additional contacts for purchase | "All per month products require an annual contract"; Marketing Cloud Next features consume Einstein Request, Messaging and Data 360 credits bought separately |
Two of the four publish a price for every package they sell (Account Engagement, and HubSpot, whose figures are starting prices). Act-On publishes one plan price at a default volume. Marketo publishes none. Act-On and Account Engagement state an annual contract on the pricing page; HubSpot's cards carry a billing toggle; Marketo's page states no contract terms.
List policy and the approval step
The fourth stage of the workflow, human-approved outreach, turns on two things a feature list leaves out: what the vendor's use policy allows you to email, and whether the platform can hold a send for someone's sign-off.
| Platform | What the use policy says about third-party lists | Approval step before a send |
|---|---|---|
| Act-On | Acceptable Use Policy (effective April 25, 2023): users "will not use non-permission based email or phone lists", meaning lists where each recipient has not opted in "as required by law" | Per-user launch setting: "Allowed" (default), "Not allowed", or "Requires Approval From {Marketing User}"; limiting sales users who send through the CRM plugin needs a support request |
| HubSpot Marketing Hub | Anti-Spam Policy (last modified February 2, 2026), 2.1.1: "strictly prohibited from using the HubSpot Services to directly contact recipients from purchased, rented, borrowed, or other third-party lists, including email append services or enrichment services lists in violation of applicable laws or third-party terms" | Content approvals for marketing email on Marketing Hub Enterprise; a Super Admin sets them up |
| Marketo Engage | Adobe's Acceptable Use Policy prohibits email to addresses obtained through "renting, purchased lists, co-registration, affiliate marketing, incomplete or old lists, or email appending" | Emails "start in draft state" and are unavailable until approved; a named-approver workflow is not described on that page |
| Salesforce Account Engagement (Pardot) | Permission-Based Marketing Policy: customers certify they "will not use rented, traded, or purchased lists, email append lists"; the help FAQ answers "Third-party lists are not allowed, no matter where they came from" | Not described in the pages cited |
Read that table before you import anything. Contacts from a B2B contact database, including Lead Seeker's, are third-party data in the sense these policies use. Each vendor sets its own terms for what may be emailed from its platform, and none of them changes because the data is accurate. Where sourced contacts go, who reviews a first message and which system sends it are decisions to make with the policy text and your counsel, before the platform is chosen.
How the four compare on running cost in people and time
The cells below are my assessment, reasoned from the vendor documentation in the tables above. They are opinion, not measurements, and no score is given because none can be read from a help article.
| Platform | Maintainability | Accuracy of one person to one CRM record | Integration burden | Operational ownership |
|---|---|---|---|---|
| Act-On | A separate Salesforce integration user with API access and without MFA for API logins, plus Create in CRM steps inside programs | Email-keyed and push-only by default; the duplicate option on Create in CRM has to stay off | Add-on on Professional; native for five CRMs; HubSpot CRM appears in Act-On's help as an example of a custom REST API integration, not among the native CRMs | Marketing operations in Act-On, with a Salesforce admin for the integration user |
| HubSpot Marketing Hub | No sync to maintain if HubSpot is the CRM; with Salesforce, a second settings screen and an inclusion segment | Strong on contacts (email); companies created through the API or the Salesforce integration need their own rule | None as the CRM; with Salesforce, up to four API calls per contact sync and Professional or Enterprise | One admin if HubSpot is the CRM; shared with the Salesforce admin otherwise |
| Marketo Engage | Sync decisions live in campaign flow steps; existing duplicates need merging by hand or the EasyMerge service | Email-keyed on new leads; duplicates created in Salesforce or by simultaneous API upserts come through | 25 API calls per sync session to check for changes, 7,200 a day at the 5-minute default, before any data moves | A Marketo admin and a Salesforce admin |
| Salesforce Account Engagement (Pardot) | Lives inside Salesforce; the connector starts paused and needs settings reviewed before it runs | CRM-ID-keyed sync is strict once linked; same-email prospects are allowed, and a prospect without a CRM ID syncs to "the first record it finds" among Salesforce duplicates | No third-party connector; Salesforce Professional Edition or higher | Salesforce admin installs; an Account Engagement admin configures, or a custom permission set delegates the setup tasks |
The pattern matches what the Match-Key Register finds for CRM builds: control is easier to keep where the platform shares the CRM's record ID, and every path that matches on email needs its own duplicate check.
Implementation: An Invented Worked Example
Halvern Coatings is an invented 70-person industrial coatings maker. Salesforce Professional Edition holds its accounts and opportunities. It has 30,000 records, emails about 3,000 of them a month, and its two reps work new contacts from a contact database each week. Every name, number and decision below is invented to show how the devices are filled in; none is a result a vendor produced.
CRM-Gravity Test, question one. Salesforce stays for the next term, so all four platforms remain. Halvern notes that Account Engagement would run inside the org it already administers.
Question two. Halvern writes its counts on the Billable-Contact Ledger: 30,000 records, 3,000 emailed a month, four marketing users. It asks Act-On to quote above the 2,500-contact default, asks HubSpot for the marketing-contact tier that covers 3,000 plus the onboarding fee, asks Salesforce whether 30,000 records fit one 10,000-contact block or need more, and asks Adobe for a Marketo quote at the same counts. The quotes go into one sheet with the annual-contract terms beside them.
Question three. Halvern's rule is that sourced contacts enter Salesforce as leads owned by a rep, and marketing emails reach them only after they opt in. The Record Path Map shows where that rule needs a setting:
- With Account Engagement, a lead created in Salesforce becomes a prospect when the connector user can see it, so Halvern would use Marketing Data Sharing to keep unconsented sourced leads out of the sync.
- With HubSpot connected to Salesforce, it would set new Salesforce leads not to create HubSpot contacts, and use an inclusion segment for the other direction.
- With Marketo, it would restrict what the Salesforce credentials in Marketo can see.
- With Act-On, the pages cited do not describe how new Salesforce records enter Act-On lists, so Halvern would ask Act-On before signing; records reach Salesforce only through Create in CRM or a form's Push to CRM.
The record path, end to end. A rep pulls a contact at an account with a dated public trigger, checks the source, and creates the lead in Salesforce from the source tool, following the import checks in exporting prospects into your CRM cleanly. The rep writes and sends the first message, as Halvern's counsel advised. If the contact asks for content, the opt-in is recorded on the lead, and only then does the record enter the automation platform's marketing sync. Halvern runs the Two-Door Test on the shortlisted platform with one test lead created from the source tool and the same person submitting a form.
Where Lead Seeker, Percepture and Pyra Fit
Lead Seeker, which publishes this page, works at the source-data and enrichment stages. It returns verified decision makers at accounts showing a dated public trigger, and saved prospects can be pushed into Salesforce or HubSpot without a second search; other CRMs take a spreadsheet export. It is not a marketing automation platform, and it does not change what the list policies above allow. Read how Lead Seeker works, see plan figures on the pricing page, or compare providers in the guide to the best B2B contact database.
Percepture, where I am President, builds AI sales agents connected to a CRM. Its guide on how to use intent data to identify sales qualified leads covers the routing stage: deciding when an account showing signals is ready for a rep rather than a nurture program.
Pyra AI, which I co-founded, builds and runs an agent for one specified workflow, with "Human-in-the-loop gates where needed", at a published $1,900 a month per production agent. An agent that writes leads to Salesforce is one more route into the Record Path Map, and its row should state which key it looks up and which records it may create.
Frequently Asked Questions
Which is better, Pardot or Marketo?
Neither is better in general; they differ on the record path. Pardot, now Account Engagement, is installed by a Salesforce admin, syncs on the Salesforce record ID every 2–4 minutes, and publishes prices from $1,250 per org per month billed annually with 10,000 contacts included. Marketo keeps its own lead database, matches new leads on email, syncs with Salesforce, Dynamics or Veeva with a 5-minute pause between syncs, and publishes no prices. In my reading of those documents, a Salesforce-only team that wants one record ID across both systems leans toward Account Engagement, and a team that needs a separate database or a non-Salesforce CRM leans toward Marketo.
Is Marketo better than HubSpot?
Start with the CRM you run. HubSpot is a CRM, so a team without Salesforce can run marketing and sales records in one system, with Marketing Hub Professional starting at $800 or $890 a month for 2,000 marketing contacts plus a $3,000 onboarding fee. Marketo is a separate marketing database that connects to Salesforce, Dynamics or Veeva and publishes no prices. With Salesforce as the CRM, compare how each creates Salesforce records: HubSpot syncs every contact unless an inclusion segment limits it, while Marketo creates one when a campaign runs a Sync Lead to SFDC step.
What are the top 5 marketing automation tools?
No neutral top five exists among the pages that rank for this question. 6sense's list of seven puts 6sense first and omits Act-On; RevSure's list of ten includes Act-On, HubSpot, Marketo and Account Engagement and is written by a company that sells a measurement layer for them. Use one rubric for every option instead: the CRM it needs, its billing unit, who creates the CRM record, its sync cadence, and what its use policy says about third-party lists.
