How we make this list: we compare pricing pages, product documentation and public user reviews. Rankite is independent; if a vendor ever pays for a featured spot, that listing is clearly labeled Partner.
Key takeaways
- HubSpot Marketing Hub Starter ($20/seat/month) is the B2B default when sales and marketing share one CRM; Professional's $890/month jump is the number to plan for.
- ActiveCampaign Starter ($15/month) delivers the deepest automation per dollar, with Plus at $49/month the real starting point for serious workflows.
- Salesforce Account Engagement ($1,250/month) and Adobe Marketo Engage (quote-only) serve enterprise B2B; both demand committed Salesforce or Adobe estates.
- Brevo ($9/month) and MailerLite ($12/month) are the budget B2B email marketing platforms, with Brevo's volume-based pricing favoring large infrequent lists.
- Mailchimp ($13/month), Constant Contact ($12/month) and GetResponse ($19/month) cover the simple end; Keap ($159/month) bundles CRM and automation for service businesses.

The best b2b email marketing software
The cost of the wrong B2B email platform is not the monthly fee. It is the list that goes cold because deliverability slipped, the automation that never got built because the workflow builder fought you, or the $890-a-month HubSpot Professional bill that arrived when Starter ran out of room. B2B email fails slowly: open rates decay, sales stops trusting marketing's leads, and nobody can point to the month it went wrong.
The second cost is pricing-model mismatch. Contact-based pricing punishes growing lists; Mailchimp at 50,000 contacts costs $385 a month. Seat-based pricing punishes growing teams. Email-volume pricing punishes frequent senders. The cheapest tool at 1,000 contacts is rarely the cheapest at 25,000, and switching platforms mid-growth means rebuilding every automation. Price the list you will have in two years, not the list you have today.
This list covers ten B2B email marketing platforms that exist today, from enterprise automation suites to budget senders.
Starting price$20 per seat/month (Starter)
Free planYes
HubSpot is the B2B default for a structural reason: marketing, sales and service share one contact record, so lead handoff and attribution work without sync jobs. Starter at $20 a seat a month covers 1,000 marketing contacts with basic automation, and the free CRM underneath is genuinely usable. For teams already on HubSpot, the email tool inherits everything.
The cliff is Professional at $890 a month with 2,000 contacts, plus a mandatory $3,000 onboarding fee. Real workflows, A/B testing and custom reporting live there. A team outgrowing Starter can see costs multiply fortyfold. Buy HubSpot when the shared CRM justifies the platform; buy it with eyes open about the Pro jump.
What we like- Native CRM shared with sales and service
- Free tools to start
- 1,700+ integrations
Watch out for- Professional jumps to $890/month plus $3,000 onboarding
- Real automation locked behind Pro
- Costs scale with seats and contacts
Starting price$15 per month (Starter)
Free planFree trial (14 days)
ActiveCampaign's workflow builder is the deepest at this price: branching journeys across email, SMS and site events with predictive sending and AI content suggestions. Starter at $15 a month covers 1,000 contacts; Plus at $49 adds the CRM and advanced automation most buyers actually want. It leads independent deliverability tests, which is the metric that matters most.
Note the Starter cap of five actions per automation, which pushes serious users to Plus, and that newer accounts count every contact including unsubscribed toward limits. For email-first B2B teams that live in automation, it is the best value on this list.
What we like- Best automation builder at the price
- Strong deliverability
- Pricing climbs gradually
Watch out for- No free plan
- Starter automations capped at five actions
- Unsubscribed contacts count toward limits on newer accounts
Starting price$1,250 per month (Growth+)
Free planNo
Account Engagement, formerly Pardot, is the B2B marketing automation for Salesforce houses: lead nurturing, scoring, account-based marketing and B2B analytics wired directly into the CRM. Growth+ starts at $1,250 a month per org billed annually, rising through Plus+ at $2,750 and Advanced+ at $4,400. The Salesforce alignment is total.
It makes no sense outside Salesforce, and even inside, it needs skilled administration. This is an enterprise purchase with enterprise implementation. For Salesforce-committed B2B organizations, the native coupling beats every integration.
What we like- Deepest Salesforce CRM coupling
- B2B marketing analytics
- Account-based marketing native
Watch out for- Starts at $1,250 a month
- Requires Salesforce commitment
- Implementation needs expertise
Starting priceSee website
Free planNo
Marketo Engage is the enterprise B2B automation standard: four packages from Growth to Ultimate, quoted by mailable database size, with the deepest segmentation, lead lifecycle and attribution modeling in the category. It connects to Salesforce, Dynamics and others without playing favorites. Large, complex B2B programs run on it.
Everything is quote-based and the platform demands dedicated marketing operations staff; there is no casual tier. Small and mid-size teams should not be here. For enterprise B2B with sophisticated needs, it remains the benchmark.
What we like- Most sophisticated B2B segmentation
- Platform-agnostic with strong CRM connectors
- Advanced attribution
Watch out for- Quote-only pricing
- Complex setup
- Needs dedicated marketing ops
Starting price$9 per month (Starter)
Free planYes
Brevo charges by emails sent rather than contacts stored, which makes it the cheapest serious option for large lists that mail infrequently. Starter at $9 a month covers 5,000 emails; the free plan sends 300 a day. Transactional email, SMS, WhatsApp and a basic CRM come in the same account.
The trade-offs: Starter keeps Brevo branding without a paid add-on, and automation depth trails ActiveCampaign. For B2B teams with big lists and modest send frequency, the economics are unmatched.
What we like- Volume-based pricing favors big lists
- Free plan with 300 emails a day
- SMS, WhatsApp and CRM included
Watch out for- Starter keeps Brevo branding unless you pay extra
- Automation depth below ActiveCampaign
- Contact caps on lower plans
Starting price$13 per month (Essentials)
Free planYes
Mailchimp is the default the world knows: Essentials at $13 a month for 500 contacts, with the biggest template library and the most tutorials. For straightforward B2B newsletters and announcements, it works fine and everyone on the team has probably used it.
The pricing model is the problem. Mailchimp charges for unsubscribed and unconfirmed contacts, and costs scale brutally: $110 a month at 10,000 contacts, $385 at 50,000. The free plan shrank to 250 contacts. It is a fine starter tool and an expensive growth tool; plan the exit before the list grows.
What we like- Largest template and tutorial ecosystem
- Easy to start
- Generous feature breadth
Watch out for- Charges for unsubscribed contacts
- Pricing climbs steeply with list size
- Free plan cut to 250 contacts
Starting price$12 per month (Lite)
Free planFree trial (14 days)
Constant Contact is the simplicity pick: Lite at $12 a month, an interface anyone can use, event marketing tools for webinars and fundraisers, and human phone support. Nonprofits and event-driven businesses have used it for years. The 14-day trial shows the whole product.
Automation is basic compared with ActiveCampaign or HubSpot, and there is no free tier. At 10,000 contacts Lite costs $120 a month. For teams that send straightforward campaigns and value a phone number to call, it does the job.
What we like- Simplest campaign builder here
- Event marketing tools
- Good phone support
Watch out for- No free plan
- Automation is basic
- $120 a month at 10,000 contacts
Starting price$19 per month (Starter)
Free planYes
GetResponse bundles what others sell separately: email marketing, automation, landing pages, funnels and webinars from $19 a month for 1,000 contacts. For B2B teams running webinar-led demand generation, the built-in webinar platform removes a separate subscription. A limited free plan exists for evaluation.
The interface and automation depth sit mid-pack, and deliverability reports vary. It is the all-in-one value play: not the best at any single thing, but the cheapest way to get email, webinars and funnels in one login.
What we like- Webinars built in
- Funnels and landing pages included
- Reasonable entry price
Watch out for- Interface less polished than rivals
- Automation depth mid-pack
- Deliverability varies by region
Starting price$159 per month (Pro, billed annually)
Free planFree trial (14 days)
Keap, formerly Infusionsoft, is the all-in-one for small B2B service businesses: CRM, email marketing, automation, appointments, invoicing and payments from $159 a month for Pro billed annually with 1,500 contacts. The lifecycle automation, from lead capture to follow-up to conversion, suits consultants, coaches and agencies with hands-on sales.
The price reflects the bundle: a $999 mandatory onboarding fee and costs well above pure email tools. If you only need email, it is overkill. If you need the CRM, the invoicing and the automation together, the consolidation can replace three subscriptions.
What we like- CRM plus automation plus invoicing in one
- Built for service businesses
- Strong follow-up automation
Watch out for- Expensive entry
- $999 mandatory onboarding
- Overkill for email-only needs
Starting price$12 per month
Free planYes
MailerLite is the clean, honest budget tool: $12 a month entry, a free plan for small lists, and an interface with no learning curve. Comfort plans scale predictably with subscribers. For B2B teams sending newsletters and basic automations without fuss, it is the least stressful option here.
Power users will outgrow it: automation, segmentation and integrations trail ActiveCampaign and HubSpot. But as the simple, cheap, reliable sender, it has earned a loyal following. Start here when the requirements are genuinely simple.
What we like- Clean simple interface
- Generous free plan
- Straightforward pricing
Watch out for- Automation simpler than ActiveCampaign
- Fewer integrations
- Support slower on free plans
How this shortlist was assembled
This list was built from vendor pricing pages, feature documentation and public reviews checked in October 2026, focused on platforms that serve B2B email marketing rather than creator or e-commerce niches. Only products available today were included. Quote-only enterprise products are marked as such. No hands-on testing was performed and no vendor paid for placement.
What to check before you commit
Model your list at two years of growth, not today. Contact-based pricing means Mailchimp and ActiveCampaign bills grow with every signup; volume-based Brevo stays flat if send frequency holds. A 10,000-contact list costs $110 on Mailchimp Essentials, $39 on Brevo Starter and $890 on HubSpot Professional. The pricing model matters more than the entry price.
Then test deliverability with your actual content. Send trials to seed addresses across Gmail, Outlook and corporate filters, and check spam placement. Independent tests rank ActiveCampaign highly, but your list, your content and your sending domain dominate the result. Authenticate with SPF, DKIM and DMARC before you judge any platform.
Automation depth versus ease
Map your three most important automations before you buy: welcome series, lead nurture, re-engagement, webinar follow-up. Build each in the trial. If the workflow builder fights you on day one, it will fight you every week. ActiveCampaign and HubSpot lead on depth; Constant Contact and MailerLite lead on simplicity.
CRM and sales alignment
B2B email fails when marketing and sales use different systems. HubSpot and Salesforce Account Engagement solve this natively; the others integrate with varying depth. Confirm two-way sync of lead status, scoring and lifecycle stage with your actual CRM before committing.
The deliverability nobody monitors
Most B2B teams set up their email platform once and never check deliverability again. List hygiene decays: hard bounces accumulate, spam complaints rise, engagement falls, and inbox providers quietly route more mail to spam. The platform is rarely the cause; the list is.
Build the habit: monthly bounce and complaint review, sunset policies for unengaged contacts, double opt-in for new sources, and dedicated sending domains for volume senders. A clean list on a budget platform outperforms a dirty list on Marketo. The tool sends the email; the list determines whether it arrives.
Frequently asked questions
What is the best email marketing platform for B2B?
HubSpot Marketing Hub is the best fit when sales and marketing share a CRM; ActiveCampaign is the best value for automation depth per dollar. Enterprise Salesforce shops should evaluate Account Engagement. The right choice depends on your CRM, list size and automation needs.
How much does B2B email marketing software cost?
From $9 a month (Brevo) to $15 to $20 (ActiveCampaign, HubSpot Starter, GetResponse) to $159 (Keap) to $890 (HubSpot Professional) to $1,250-plus (Salesforce Account Engagement) and quote-based (Marketo). Price your list at two years of growth, since contact-based pricing climbs with every signup.
Is HubSpot or ActiveCampaign better for B2B?
HubSpot wins when marketing, sales and service need one shared CRM and you can afford Professional's $890 a month. ActiveCampaign wins on automation depth per dollar for email-first teams, with Plus at $49 a month covering most B2B needs. Small teams usually get more from ActiveCampaign; scaling teams often graduate to HubSpot.
Do I need marketing automation or just email marketing?
If you send newsletters and announcements, email marketing suffices. If you nurture leads over weeks, score them, route them to sales and personalize by behavior, you need automation. B2B buying cycles are long; automation pays for itself the first time a nurtured lead closes without manual follow-up.
How do I improve B2B email deliverability?
Authenticate your domain with SPF, DKIM and DMARC, clean hard bounces monthly, sunset unengaged contacts, avoid purchased lists entirely, and warm up new sending domains gradually. Monitor spam complaint rates and inbox placement, not just opens. List hygiene matters more than platform choice.
Can I switch email marketing platforms later?
Yes, but it costs real effort: rebuilding automations, migrating templates, rewarming sending reputation and reintegrating the CRM. Export your list and automation documentation regularly so you are never locked in. Choose with a two-year horizon to avoid switching during growth.
