The best email marketing software for B2B (2026)
Copy for AI
The best B2B email marketing software is the one that fits your sales process.
There’s no single winner. For most Belgian B2B marketers, Brevo, ActiveCampaign and HubSpot come out strongest.
The verdict: pick on automation and CRM connection, not on templates. A pretty newsletter tool that can’t talk to your pipeline stays an island.
Mailchimp and MailerLite are solid starting points. Klaviyo is mainly at home in e-commerce.
How we checked: every price below comes from the vendor’s own pricing page, checked on 18 October 2026, in the currency the page showed. The screenshots were taken the same day, logged out.
No vendor pays us to be listed.

|---|---|---|---|
| Brevo | Email plus a light CRM at a sharp price | 300 emails a day | $9/month (Starter) |
| ActiveCampaign | Deep automation and nurturing | 14-day trial | $15/month, billed annually (1,000 contacts) |

Free plans differ more than you’d think. Here’s how much each one lets you send:
Brevo’s free plan sends the most.
But a free plan shows where you start, not where you’ll end up.
How do you recognize good email marketing software for B2B?
Templates and colors matter least. In B2B, it comes down to two things: do your emails arrive, and does the system move with your sales process?
Check these five points:
- Deliverability: inbox placement, SPF, DKIM, DMARC
- Automation: multi-step flows that react to behavior
- CRM integration: a live link to your sales pipeline
- Segmentation: by role, industry or deal stage
- Price per contact: what your list costs in two years
Deliverability comes first
The prettiest campaign is worthless if it lands in spam.
Gmail has strict rules for bulk senders, meaning over 5,000 messages a day.
They must set up SPF, DKIM and DMARC, offer one-click unsubscribe and keep spam rates below 0.30%.
Pick a tool that supports all of that, plus dedicated sending domains. Our guide to improving email deliverability walks you through the setup.
Automation beats newsletters
Can you build flows that respond to a download, a click or a website visit? For B2B, that matters more than standalone newsletters.
Why? Your leads have a long decision cycle. Flows such as lead nurturing email flows keep them warm between sales calls.
CRM and segmentation decide relevance
Does the tool talk to your CRM, or is it a CRM itself? That’s the key difference between B2C tools and real B2B machines.
Good email list segmentation often doubles your relevance. Segment by role, industry or deal stage, for example, not just by open date.
Price per contact adds up
Almost every tool charges per contact or per send. That adds up fast as your list grows.
Tip: run your scenario first with a realistic contact count for next year, not today’s list.
Which email marketing tools are the best for B2B?
We’ve built flows in HubSpot, ActiveCampaign and Brevo ourselves: contact to newsletter, active and inactive leads, lead scoring and drip campaigns. Here’s how all seven compare.
1. Brevo (formerly Sendinblue)
Best for: SMEs that want email and a light CRM in one tool.
Biggest strength: email, automation, a built-in CRM and SMS in one package.
Price: Starter $9, Standard $18 and Professional $499 a month, billed monthly (pricing page, checked 18 October 2026).
Watch out: plans are tiered by email volume, and Starter begins at 5,000 emails a month.
Brevo is the most balanced choice for many Belgian B2B companies. Look at what each tier adds:
Brevo’s pricing page, US settings, billed monthly, 18 October 2026. Marketing automation only starts on Standard.
Volume-based pricing is favorable if you have a large list but send little. The free plan allows 300 emails a day once your account is approved.
2. ActiveCampaign
Best for: B2B teams that invest seriously in nurturing and scoring.
Biggest strength: one of the best flow builders in its class, with branching on behavior.
Price: Starter from $15, Plus $49, Pro $79 and Enterprise $145 a month, billed annually, for 1,000 contacts (pricing page, checked 18 October 2026).
Watch out: lead scoring and the sales pipeline come with the Pipelines and Enhanced CRM add-ons, not in the base email plans.
If automation is your main reason, ActiveCampaign sits at the top. Here’s the pricing grid at 1,000 contacts:

The price scales with your contact count, so calculate ahead.
There’s a 14-day free trial, and you don’t need a credit card.
3. HubSpot
Best for: teams that want their entire funnel in one system for years.
Biggest strength: the tight link between marketing, CRM and sales.
Price: Marketing Hub Starter from $7 per seat a month on a limited-time offer for new customers. Professional costs from $800 a month with 3 seats, plus a one-time $3,000 onboarding fee (pricing page, checked 18 October 2026).
Watch out: the plans get steep fast as your contact numbers grow.
HubSpot isn’t an email tool.
It’s a full marketing and sales platform, and email is one part of it.
Our screenshot came out in euros, even with US settings:
HubSpot’s pricing page, billed monthly, 18 October 2026. The page showed euros; the USD switch didn’t apply.
Choose HubSpot if you’ll grow into the platform. If you only want to send newsletters, it’s overkill. Our guide to HubSpot website integration shows the next step.
4. Mailchimp
Best for: teams that start simple.
Biggest strength: the best-known name, with an accessible interface and neat templates.
Price: free up to 250 contacts and 500 sends a month. Essentials starts at $13 and Standard from $20 a month after a 14-day trial (pricing page, checked 18 October 2026).
Watch out: basic automation next to ActiveCampaign, and the price per contact rises faster than you expect.
The free tier is small. Note the limits in the left column:
Mailchimp’s pricing page, US settings, 0 to 500 contacts, 18 October 2026. Sending pauses once you pass a limit.
Good for a simple start, less so for deep flows and CRM logic.
5. Klaviyo
Best for: webshops.
Biggest strength: deep links with webshops, product behavior and purchase data.
Price: free for up to 250 active profiles and 500 emails a month. The pricing page didn’t show a paid starting price on 18 October 2026.
Watch out: for B2B with long cycles and personal deals, the e-commerce focus is overkill.
Klaviyo is excellent, but almost entirely built for B2C selling. The free plan is the easiest way to test it:

Run a webshop? Choose Klaviyo. Sell services or complex products? Look higher up this list.
6. MailerLite
Best for: small B2B teams or freelancers on a small budget.
Biggest strength: simple, affordable and surprisingly complete, with landing pages included.
Price: free for 250 subscribers and 2,500 emails a month. Comfort starts at $12 and Power from $25 a month (pricing page, checked 18 October 2026).
Watch out: shallower automation and segmentation than ActiveCampaign, and no full CRM.
Billed yearly, the plans get 10% cheaper. Here’s the grid at 500 subscribers:
MailerLite’s pricing page, US settings, 500 subscribers, billed yearly, 18 October 2026.
It’s the lightweight choice. You’ll get going without a steep learning curve.
7. Campaign Monitor
Best for: marketers who care most about how their emails look.
Biggest strength: beautiful, brand-consistent templates and ease of use.
Price: Lite €10.80, Essentials €26.10 and Premier €142.20 a month for up to 500 contacts. That’s billed annually (pricing page, checked 18 October 2026).
Watch out: less depth on automation and CRM than the B2B leaders above.
The pricing page showed euros and offered no currency switch:
Campaign Monitor’s pricing page, 0 to 500 contacts, annual billing with 10% off, 18 October 2026.
A solid pick when brand experience matters more than advanced flows.
Which one should you choose?
Pick by profile:
- Email plus light CRM, sharp price: Brevo
- Automation and lead scoring first: ActiveCampaign
- All marketing and sales in one platform: HubSpot
- Just starting: Mailchimp or MailerLite
- A webshop: Klaviyo
- Design first: Campaign Monitor
