Best Platforms for B2B Marketing in 2026: 9 Platforms Compared

HubSpot Marketing Hub is the most complete starting point for B2B teams because marketing, sales and service share one contact record. The free tools cover basic CRM, email and forms, Starter runs around $15 per seat per month, and Professional, at roughly $890 per month for 2,000 contacts, adds advanced automation, ABM tools and custom reporting. That shared record is what makes sales and marketing alignment real instead of theoretical.

The price jump to Professional is the main drawback, along with onboarding fees at higher tiers. Small teams can stay on free or Starter for a long time, but growing teams should budget for the jump. For most B2B companies that want one platform, HubSpot is the default choice.

Marketo Engage, now part of Adobe, is the enterprise B2B marketing automation standard. It handles complex lead scoring, multi-step nurture programs, account-based marketing and attribution across long sales cycles, and it integrates deeply with Salesforce and Microsoft Dynamics. Pricing is quote-only and commonly runs to tens of thousands of dollars per year.

Marketo is not a small-team tool: it needs trained staff and a clear data model to work well, and smaller companies will find it heavy. For enterprises with complex buying committees and long cycles, it remains the benchmark that other platforms are measured against.

Salesforce Account Engagement, formerly Pardot, is the natural marketing automation choice for companies already running Salesforce. Leads, campaigns and scoring sync directly with Salesforce records, so sales sees the same data marketing sees. The Growth tier starts around $1,250 per month for 10,000 contacts, with Advanced tiers at $4,000 or more per month.

The catch is that Account Engagement requires Salesforce CRM, so the total cost includes both products. Companies not on Salesforce should look at HubSpot or Marketo instead. For Salesforce-native B2B teams, though, the integration is hard to beat.

ActiveCampaign gives small and mid-sized B2B teams automation depth that used to cost enterprise money. Starter starts at $15 per month for 1,000 contacts billed annually, with Plus around $49 and Professional around $79, adding split automation, predictive sending and more. The visual automation builder handles multi-step journeys, scoring and site tracking without a separate tool.

There is no free plan, only a 14-day trial, and pricing rises with contacts, so a growing list raises the bill. ActiveCampaign is the best B2B marketing software for teams that live in automation and want the most capability per dollar.

Mailchimp is best known for email, and it remains a strong email-first option for B2B teams with smaller lists. The free plan covers 500 contacts and up to 1,000 emails per month, Essentials starts around $13 per month for 500 contacts, and Standard around $20. The email builder is easy, and basic automation and segmentation cover newsletters, welcome series and simple nurture flows.

Mailchimp is weaker than HubSpot or Marketo on B2B lead scoring, CRM depth and account-based features, so larger B2B teams will outgrow it. For a small B2B company whose marketing is mostly email and content, it is affordable and easy to run.

Semrush is a marketing toolkit rather than a marketing automation platform: it covers keyword research, competitor analysis, content ideas, site audits, rank tracking and advertising research. The Pro plan starts at $139.95 per month, and it is the tool many B2B content teams use to decide what to write and which keywords to target. Social posting and basic CRM features are included, but they are not the core.

Semrush does not replace HubSpot or Marketo for email automation and lead nurturing. It pairs with them: Semrush finds the demand, and the automation platform converts it. B2B teams investing in search and content should budget for Semrush alongside, not instead of, a marketing platform.

Demandbase is an account-based marketing platform that helps B2B teams target whole accounts rather than individual leads. It identifies anonymous site visitors by company, layers in intent data, and runs advertising and sales plays against target accounts. Pricing is quote-based and aimed at mid-market and enterprise teams.

Demandbase works best alongside a marketing automation platform and a CRM, not as a replacement for either. Companies without a target account list and a sales team ready to act on account signals will not get full value. For ABM programs, it is one of the most complete options.

6sense uses AI and intent data to predict which accounts are in market and what stage of buying they have reached, then orchestrates ads, email and sales outreach against those accounts. That prediction layer is what sets it apart from simpler ABM tools. Pricing is quote-based and typically enterprise-level, with reported annual costs in six figures for larger deployments.

6sense needs clean CRM data and a sales team that acts on its signals, so smaller teams may not see the return. For enterprises running ABM at scale, its intent data and predictions are among the strongest available.

Terminus focuses on account-based advertising and engagement: it runs targeted ads to buying committees at target accounts and measures engagement at the account level. It integrates with major CRMs and marketing automation platforms, so ad engagement feeds back into lead scoring and sales alerts. Pricing is quote-based.

Terminus is narrower than Demandbase or 6sense, since its strength is advertising rather than full intent prediction. That focus suits teams that already have a marketing platform and want to add account-based ads. As a standalone tool it is incomplete, but as part of an ABM stack it is effective.
