The best B2B marketing automation platforms in 2026 are HubSpot Marketing Hub (SMB and mid-market), Adobe Marketo Engage (enterprise demand generation), Salesforce Marketing Cloud Account Engagement (Salesforce-only teams), Oracle Eloqua (CRM-neutral enterprise) and ActiveCampaign (small teams). Each reports on the touchpoints it owns, and none attributes pipeline across the whole stack, which is why teams pair them with a go-to-market context layer such as RevSure.
The platforms at a glance
What changed in the category this year
Fewer teams are switching platforms. The MarTech Replacement Survey 2025, published in March 2026 from 207 respondents, found that marketing automation replacement fell to 19% from 31% a year earlier, and CRM replacement fell to 10% from 22%. Better features remained the top reason to replace a tool, cited by 57%, while cost reduction jumped to 44% from 23% a year earlier, the survey's fastest-rising driver. RevSure's read is that the shift reflects something the survey does not ask: teams have learned that a new sending platform does not fix a reporting problem.
At the same time the vendors have made staying put harder. Salesforce is steering Account Engagement customers toward Marketing Cloud Next, Adobe has placed a new tier above Marketo Engage, Oracle retired Eloqua's native Salesforce connector, and Act-On changed hands. Whichever way a team leans, a platform decision made in 2023 now has a migration question attached to it.
The ten below are ordered by how often each one turns up in the customer stacks RevSure connects to, most common first. 6sense and Demandbase, which appeared on the earlier version of this list, are covered separately, because neither is a sending platform.
1. HubSpot Marketing Hub
Best for: SMB and mid-market teams that want one system.
Marketing Hub sits on HubSpot's own CRM, so forms, email, landing pages, workflows and reporting share one contact record without an integration project. The published price list runs from a Starter tier at $7 per seat to Professional at $800 a month for three seats plus a $3,000 onboarding fee, and Enterprise at $3,600 a month for five seats plus $7,000 onboarding. In April 2026 HubSpot moved two Breeze agents to outcome pricing: $0.50 per resolved customer conversation and $1 per lead recommended for outreach from the prospecting agent.
Where it stops: cost, and the edge of HubSpot. Contact tiers and seat fees climb quickly past 50,000 contacts. HubSpot's attribution reporting sees HubSpot touchpoints clearly and everything else dimly, so a team running paid social, a partner programme and an outbound motion in Salesforce will find that HubSpot's revenue report and Salesforce's disagree, and neither can explain the gap.
Typical buyer: $5M to $200M revenue, marketing team of two to twenty, no dedicated marketing ops engineer.
2. Adobe Marketo Engage
Best for: enterprise demand generation.
Marketo handles lead scoring, nurture streams, segmentation and programme management at contact volumes few platforms on this list have been proven at. At Adobe Summit in April 2026, Adobe placed it inside the renamed Adobe CX Enterprise umbrella and launched Journey Optimizer B2B Edition Prime, a lower-cost tier that runs on Marketo data and sits between Marketo Engage and AJO B2B Edition Ultimate, the top tier with Real-Time CDP. Marketo is staying, with a ceiling now placed above it.
Where it stops: it needs a Marketo admin, and often a consultancy behind the admin. Reporting is programme-level. Marketo knows which programme a lead touched and what the programme cost, and what the opportunity did afterwards depends on the CRM handing data back cleanly, which the CRM rarely does.
Typical buyer: enterprise marketing operations team with a Marketo specialist on staff and a Salesforce or Dynamics CRM.
3. Salesforce Marketing Cloud Account Engagement (Pardot)
Best for: Salesforce-only teams that want lead management inside the CRM.
Account Engagement's strength has always been that it is Salesforce. Scoring, grading and nurture act directly on Lead, Contact and Campaign objects. Sales sees marketing activity on the record without a sync, and the security review is already done.
Where it stops: the roadmap. Salesforce announced Marketing Cloud Next in June 2025 as its agentic marketing product. The Summer '26 release gave Account Engagement one notable update, a consent-management change described as easing migration to Marketing Cloud Next, while Agentforce Marketing received AMPscript support, RCS messaging and new agents. Existing Pardot customers should plan a migration on their own timetable rather than Salesforce's, and new buyers should ask which product they are being sold a roadmap for.
Typical buyer: mid-market to enterprise organisation that runs sales entirely in Sales Cloud and wants marketing to live there too.
4. Oracle Eloqua
Best for: CRM-neutral enterprise automation.
Eloqua is the platform for large organisations that do not want their marketing system to assume a CRM. It handles cross-channel orchestration and complex segmentation for regulated industries. Oracle continues to invest: the 26B release in May 2026 added AI features and began a Redwood interface refresh, and the June 2026 roadmap session showed no end-of-life signal.
Where it stops: Oracle retired the native Eloqua-to-Salesforce integration in the November 2025 release, and every Salesforce-connected Eloqua customer has had to migrate to a new integration app. The Redwood refresh is in progress rather than finished, the learning curve is steep, the partner ecosystem is smaller than HubSpot's or Adobe's, and implementations run long.
Typical buyer: large enterprise, often on Dynamics or Oracle CX Sales rather than Salesforce, with a marketing technology team.
5. Dynamics 365 Customer Insights - Journeys
Best for: organisations standardised on Microsoft.
Customer Insights - Journeys is Microsoft's marketing automation product, formerly Dynamics 365 Marketing, and it is the obvious choice for a company whose sales team lives in Dynamics 365 Sales. The 2026 release wave 1, running April to September 2026, added Copilot-assisted journey creation, direct lead creation from journeys using behavioural and predictive signals, and tighter connection between Customer Insights - Data and Journeys.
Where it stops: outside Microsoft. The partner and template ecosystem is thinner than HubSpot's or Marketo's, and teams on Salesforce have no reason to look at it.
Typical buyer: mid-market to enterprise organisation on Dynamics 365 Sales and Microsoft 365.
6. Act-On
Best for: mid-market teams that want CRM-agnostic automation without an enterprise contract.
Act-On has sold affordable marketing automation to mid-market companies for years, with email, lead scoring, nurture and native integrations to Salesforce, Microsoft Dynamics, SugarCRM and NetSuite. Banzai acquired it for $53.2 million in January 2025.
Where it stops: depth. Act-On is a smaller product than Marketo and a smaller company than HubSpot, and buyers should ask what the post-acquisition roadmap looks like before committing to a multi-year term.
Typical buyer: mid-market marketing team of three to fifteen, on a CRM other than HubSpot, that has priced Marketo and walked away.
7. ActiveCampaign
Best for: small teams.
ActiveCampaign combines email automation, a built-in CRM and a set of AI agents it calls Active Intelligence, opened to all customers in October 2025 along with a remote MCP. In February 2026 it put a published results guarantee behind its autonomous marketing features, which is rare on this list.
Where it stops: reporting and account-based work. It is a lead-centric tool with a usable CRM, and teams that move into account-based marketing or need revenue-level reporting outgrow it.
Typical buyer: SMB with a small marketing team and no appetite for a HubSpot Professional contract.
8. Brevo
Best for: low-cost multichannel.
Brevo, formerly Sendinblue, closed a funding round above €500M in December 2025, becoming a unicorn on more than €200M of ARR, and has earmarked €100M for US growth through 2030. It does email, SMS and WhatsApp automation at prices that make it the practical choice for SMB teams that want more channels than HubSpot Starter offers.
Where it stops: B2B depth. Lead scoring and account-based features trail HubSpot and Marketo, and its CRM is light. Its stated ambition is to challenge the CRM incumbents, which is not yet the same as being ready for a complex B2B funnel.
Typical buyer: SMB, increasingly mid-market, especially in Europe.
9. Zoho Marketing Automation
Best for: Zoho suite customers.
Zoho Marketing Automation is a competent product priced by contact volume, and the obvious choice for organisations already on Zoho CRM or Zoho One. It does what it says at a lower price than any enterprise platform here.
Where it stops: the ecosystem. Integrations outside Zoho are thinner, and the AI and account-based capabilities lag the leaders. A team that is not on Zoho CRM has little reason to pick it.
Typical buyer: cost-conscious SMB already inside the Zoho suite.
10. Customer.io
Best for: product-led B2B messaging.
Customer.io triggers journeys from events: a user signed up, activated a feature, went quiet, or crossed a usage threshold. Its Summer 2026 release added geofencing, live iOS lock-screen notifications, a notification inbox and a WhatsApp template builder. For a product-led B2B SaaS company with usage data in a warehouse, it is the right tool, and it earns its place on a B2B list because that segment keeps growing.
Where it stops: classic demand generation. Lead scoring, CRM-synced nurture and account-based workflows are not what it was built for, and it reaches Salesforce and HubSpot through connectors rather than natively.
Typical buyer: PLG SaaS company with a warehouse or CDP already in place.
6sense and Demandbase: the layer above the sending platform
Both names appeared on the earlier version of this list, and both are asked about constantly, so a word on where they sit. 6sense and Demandbase One identify accounts showing buying intent, score them, and orchestrate advertising, email and sales plays against those accounts. In July 2026 6sense released an MCP Server so agents in Claude, ChatGPT and Agentforce can query its account intelligence directly; Demandbase's April 2026 update added its own MCP gateway and a new Salesforce Data Integrity integration.
They are deployed alongside HubSpot, Marketo or Account Engagement, which do the sending, and they are the right answer when the question is which accounts to pursue. RevSure integrates with both and reads their intent and buying-group signals into its context layer alongside the CRM, so the accounts they surface can be followed through to pipeline on one reconciled record.
What the ten report, and what they cannot
Every platform above reports accurately on what it did. HubSpot reports on HubSpot emails and forms. Marketo reports on Marketo programmes. Each report is internally correct, and none of them answers the CFO's question, which is which of these created the pipeline that closed, and where next quarter's budget should go.
The answer lives across records no single platform owns: a campaign in Marketo, a contact in Salesforce under a second email address, an opportunity a rep created from a phone call with no campaign attached at all. A contact centre AI company found on a RevSure onboarding call that its outbound automation was loading 500 to 2,000 records a week that its marketing automation platform then counted as leads and MQLs, and that more than 400 of those MQLs had never been touched by anyone. A healthcare software company on its kickoff call described years of cleanup work in its marketing automation platform that was, in its own words, "never going to be perfect", a Salesforce campaign count it put in the five-digit thousands, and 90 to 95% of its Google and LinkedIn ad clicks landing on the website and losing their attribution there, so that "everything in Salesforce is showing up as website."
This is the job RevSure does, and it is not a job a marketing automation platform can do. RevSure does not send email, build forms or run nurture, and nobody should buy it to replace anything on the list above. It is the go-to-market context layer that sits under the marketing automation platform and the CRM, resolves the campaign, contact, account and opportunity records they create into one Full Funnel Data Graph, and then runs attribution, forecasting and AI GTM agents on that reconciled record. That last part is where the category is heading: the same teams asking which campaign worked are now putting agents on their GTM data, and an agent pointed at an unreconciled CRM inherits every duplicate and missing campaign at machine speed. The context layer is what an agent can safely act on.
The first thing a new customer does is try to break it, by pulling six months of Salesforce reports and checking whether the numbers match on day one. When they do, the marketing report and the sales forecast agree, because they were built on the same record. A marketing leader at one customer described the effect in the room with sales: any account executive now "has to think twice about calling us out."
If the problem is sending better campaigns, pick from the ten. If the problem is that the record underneath them is not something a forecast or an agent can trust, that is a RevSure problem, and pricing is published.
How to choose
Start with the CRM, because the marketing automation platform will spend its life syncing with it, and pick the platform native to it unless there is a strong reason not to. Lead-based and account-based motions then diverge: account-based motions pair a sending platform with 6sense or Demandbase on top of it.
The last question is the one none of the vendors will volunteer: when the CRO says marketing's pipeline number is wrong, what in this stack proves otherwise? If the answer is a dashboard inside the marketing automation platform, the argument will be lost, because the CRO does not believe that dashboard. The revenue intelligence platforms comparison covers the layer that changes that.
Frequently asked questions
What is the best B2B marketing automation platform?
For most SMB and mid-market teams, HubSpot Marketing Hub, because CRM, email, forms and reporting share one record. For enterprise demand generation at high contact volumes, Adobe Marketo Engage. For Salesforce-only organisations, Marketing Cloud Account Engagement, with the caveat that Salesforce is moving investment to Marketing Cloud Next. None attributes pipeline across the stack.
Is RevSure a marketing automation platform?
No. RevSure does not send email, build forms or run nurture. It is the go-to-market context layer that sits under the marketing automation platform and the CRM, resolves their records into a Full Funnel Data Graph, and runs attribution, forecasting and AI GTM agents on that reconciled record. HubSpot or Marketo still do the sending.
Is Pardot being discontinued?
Salesforce has not announced an end of life for Marketing Cloud Account Engagement. It has announced Marketing Cloud Next and Agentforce Marketing as its agentic marketing products, and recent releases have concentrated new features there. Existing customers should plan a migration on their own timetable and ask Salesforce for roadmap commitments in writing.
Are 6sense and Demandbase marketing automation platforms?
They are account intelligence and orchestration platforms rather than sending platforms. Both identify in-market accounts and coordinate advertising, email and sales plays against them, working alongside HubSpot, Marketo or Account Engagement, which deliver the nurture email. RevSure integrates with both and reads their signals into the funnel record.
How much does B2B marketing automation cost?
HubSpot publishes Marketing Hub Professional from $800 a month for three seats plus $3,000 onboarding, and Enterprise from $3,600 a month plus $7,000 onboarding. Marketo, Account Engagement, Eloqua and Dynamics 365 Customer Insights are quoted, and enterprise contracts commonly reach six figures a year. Brevo, Zoho and ActiveCampaign price by contact volume at SMB levels.
Why do the marketing automation report and the CRM report disagree?
They are built on different records. The marketing platform counts each contact once, while the CRM may hold the same person twice, on a subsidiary account, attached to an opportunity with no campaign linked. Each report is internally correct on its own data. Reconciling them takes identity resolution across both systems, which is what RevSure's Full Funnel Data Graph does.
