Choosing a B2B email marketing platform isn’t just a tech decision—it’s a strategic one. And if you’re anything like most business leaders we talk to, you’ve probably had this moment:
You open a dozen tabs—Mailchimp, HubSpot, Constant Contact, ActiveCampaign. You scroll through pricing tables, stare at acronyms, skim feature lists, and wonder why something as “simple” as email marketing feels like it requires an MBA in Martech.
We’ve worked with many of these platforms—some for our own marketing, some through client engagements. While we haven’t used every single tool on this list firsthand, we’ve helped plenty of businesses wrestle with the same question: Which B2B email marketing platform is going to help us grow without making us lose our minds?
What You Should Expect From a B2B Email Marketing Platform
Before diving into each option, here’s what you should expect from a solid B2B email marketing platform in 2025:
- Clean, intuitive interface (no tech degree required)
- Automation that works without constant fixing
- AI tools that actually help—not just buzzwords
- CRM integration (or at least the ability to play nice with one)
- Reporting that gives you insights—not just numbers
Not every platform hits the mark. But when you find the one that fits your team, your audience, and your growth plan—it changes the game.
Let’s Compare the Top B2B Email Marketing Platforms
There’s no shortage of email tools out there—but most weren’t built with B2B in mind. That’s why we’ve narrowed the list to platforms that work well for professional services, SaaS, consulting, and other relationship-driven industries.
Some are simple and affordable. Others are full-blown CRMs with all the bells and whistles. But every tool on this list has a specific strength—and understanding that can save you hours of research (and a few headaches).
Let’s dig into the 10 top contenders and see which one fits your goals.
Mailchimp – Simple, Familiar, and Sometimes Limiting
Mailchimp is the tool many businesses start with—and for good reason. It’s like the Honda Civic of email marketing: affordable, reliable, easy to drive.
Pricing (2025):
- Free plan: Up to 500 contacts
- Essentials: $13/month
- Standard: $20/month
- Premium: $350+/month for larger lists
What You Get:
A super intuitive email builder, helpful templates, basic automations, and clear reporting. Their AI features (like subject line suggestions and layout recommendations) are decent, especially if you’re not a copywriter by trade.
But here’s the catch: it’s great until it’s not. If you want to segment contacts based on behavior or build multi-step automations, you’ll run into limitations fast.
Real B2B Use Case:
A local IT provider wants to send a clean monthly newsletter, highlight new services, and maybe run a quarterly promotion. Mailchimp gives them just enough functionality to look polished without overcomplicating things.
Good for: Small businesses that need a basic email engine.
Watch out for: Limited automation, clunky CRM integration.
ActiveCampaign – When It’s Time to Start Nurturing, Not Just Notifying
ActiveCampaign is a powerful B2B email marketing platform designed to enhance your marketing strategy. It’s where you go when you’re done blasting newsletters and want to actually guide people through a buying journey.
Pricing (2025):
- Starts at $19/month; scales with contact count
- Pricing scales significantly—e.g., at 2,500 contacts, plans go up to ~$39/mo (Starter) to $149+ (Pro)
What You Get:
This platform lets you build behavior-based automations: “If someone downloads this guide, visits that pricing page, and doesn’t respond to our follow-up… send a re-engagement sequence in three days.” It’s that smart.
Add in AI tools—like predictive send-time optimization, tone analysis, and workflow generation—and you’ve got a platform that grows with your strategy.
Yes, there’s a learning curve. But once it’s dialed in, ActiveCampaign can help you send the right message at the right time—without babysitting every campaign.
Real B2B Use Case:
A regional accounting firm works with different client types—SMBs, high-net-worth individuals, and family offices. They use ActiveCampaign’s tagging and segmentation to tailor content based on client type and engagement history, creating nurture paths that actually convert.
Good for: Companies ready to do more than send a monthly newsletter.
Watch out for: The interface isn’t the prettiest, and setup takes time.
HubSpot – The All-In-One Marketing Ecosystem
HubSpot is much more than a B2B email marketing platform. It’s where email marketing stops being just email—and becomes part of a much bigger picture. If you want your CRM, blog, sales tools, and automation to all live under one roof, HubSpot is your tool.
Pricing (2025):
- Starter: $20/month
- Professional: ~$500/month
- Enterprise: ~$1,500/month
What You Get:
HubSpot includes an AI suite (“HubSpot Copilot”) that helps you write emails, score leads, analyze campaign performance, and even generate CTAs. Its reporting is excellent, integrations are seamless, and the support is stellar.
That said, the pricing scales quickly. If you’re not using the full suite—CRM, sales enablement, reporting—it can feel like overkill.
Real B2B Use Case:
A consulting agency uses HubSpot to handle everything from top-of-funnel lead capture to handoff to sales. They track every touchpoint—email opens, webinar signups, page visits—and route high-quality leads to the right rep automatically.
Good for: Businesses ready to align sales, marketing, and customer service.
Watch out for: Cost scales quickly. You’ll want a plan (and a budget).
Constant Contact – Reliable, No-Frills Email Campaigns
Constant Contact has been around forever. It’s straightforward, easy to navigate, and their support is helpful if you’re the kind of person who wants to talk to a human before launching a campaign.
Pricing (2025):
- Starts at ~$12–$35/month
What You Get:
A reliable platform for sending emails that get delivered. It includes basic templates, scheduling, contact list management, and some light automation. It won’t wow you with AI features or segmentation magic—but it gets the job done.
Real B2B Use Case:
A commercial HVAC company uses Constant Contact to send reminders about seasonal maintenance and system upgrades. They don’t need advanced workflows—they just need to stay in front of their clients and make it easy to book a service.
Good for: Local service businesses or nonprofits that want simple email tools.
Watch out for: Less flexible automation and reporting.
Kit (formerly ConvertKit) – Clean, Email-Focused for Service Providers
Kit price and plans (2025):
- Free “Newsletter” plan: Up to 10,000 subscribers; includes one visual automation and one email sequence
- Creator plan: From $29/month (for up to 1,000 subs), scales with list size; includes unlimited visual automations, API access, free migrations, and integration with tools
- Creator Pro plan: From $59/month (1,000 subs); adds advanced features like deliverability analytics, engagement scoring, Facebook audiences, priority support, and referral tools.
AI and automation:
- Kit offers a visual automation builder and prebuilt templates for workflows—but it doesn’t have true generative AI (no auto-generated content or predictive sending yet)
- No built-in AI suggestions for subject lines or content, unlike higher-tier AI platforms.
What it does well:
- Generous free plan with solid automations for growing lists.
- Clean UI focused on email-first workflows and B2B-friendly automations.
- Easy onboarding with free migration help
Limitations for B2B:
- Lacks built-in CRM—so you’ll need Zapier or another CRM for contact management and behavior tracking.
- No advanced AI tools, which may be a downside if you want auto-generated content or predictive analytics.
Real B2B use case:
A consulting firm educating prospects via email sequences could use Kit’s free plan to start building welcome workflows and lead magnets. As their list grows, they can upgrade to Creator or Pro for more automation complexity—while keeping communications clean and focused.
Salesforce Marketing Cloud – Powerful… and Pricey
Salesforce Marketing Cloud is the go-to for enterprise B2B companies with complex sales funnels and a team to manage it all. It’s a beast—in both power and setup.
Pricing (2025):
- Plans start around $1,250–$2,500/month, depending on features
What You Get:
Enterprise-grade automation, robust CRM integration, advanced reporting, and full-blown multi-channel orchestration. It’s a full marketing command center—but only if you’ve got the resources to drive it.
Real B2B Use Case:
A national professional services firm uses Salesforce Marketing Cloud to coordinate account-based marketing (ABM) for key clients. Different teams send personalized campaigns to C-level executives, while tracking every engagement across departments.
Good for: High-growth companies with sales and marketing alignment.
Watch out for: Complexity and cost. You’ll need tech support (and patience).
Brevo (formerly Sendinblue) – Budget-Friendly with Big Features
Brevo is one of the most affordable B2B email marketing platforms with surprising depth for the price—especially if you want multi-channel communication.
Pricing (2025):
- Free tier: 300 emails/day
- Paid plans start around $25/month
What You Get:
Email + SMS + WhatsApp + chat, plus a lightweight CRM and automation features. The interface is clean, and setup is quick. The AI tools aren’t advanced, but if you’re looking for solid features on a small budget, Brevo shines.
Real B2B Use Case:
A SaaS startup uses Brevo to send onboarding sequences, support check-ins, and product updates—while also testing SMS reminders for webinar attendance. It’s their marketing hub while they scale.
Good for: Teams that want more than email without breaking the bank.
Watch out for: Fewer integrations and limited AI depth.
GetResponse – A Multi-Channel Platform Worth Exploring
GetResponse quietly packs a lot into its offering—email, automation, CRM, chat, and even webinars. It’s an under-the-radar option for B2Bs that run events or training.
Pricing (2025):
- Email marketing: $19/month
- Automation + webinars: ~$49/month+
What You Get:
Flexible email workflows, list segmentation, AI-generated emails, and built-in webinar hosting. If your B2B strategy includes regular live demos or workshops, this one’s worth a look.
Real B2B Use Case:
A compliance tech company hosts a monthly “Ask the Expert” session for buyers. GetResponse handles everything from registration emails to post-event follow-up, keeping everything streamlined in one place.
Good for: Businesses that want to run email, landing pages, and webinars from one platform.
Watch out for: Some interface quirks and a bit of a learning curve.
MailerLite – Clean, Affordable, and Surprisingly Capable
MailerLite is like that reliable teammate who never complains, gets the job done, and stays out of your way. It’s not flashy—but it’s good.
Pricing (2025):
- Free for up to 1,000 contacts
- Paid plans: $10–$35+/month
What You Get:
Clean templates, simple automation workflows, landing pages, and solid support. While it lacks advanced CRM features, it’s more than enough for small teams looking to upgrade from Mailchimp.
Real B2B Use Case:
A boutique marketing firm uses MailerLite to publish a weekly email roundup of trends, schedule campaign announcements, and offer lead magnets—without needing a dedicated tech person.
Good for: Small teams who want clean design and solid automation.
Watch out for: Basic reporting, limited CRM functionality.
Klaviyo – Smart Segmentation for Data-Driven Teams
Known for ecommerce, Klaviyo has quietly built features that make it a strong B2B email marketing software option—especially for teams that love analytics and precision targeting.
Pricing (2025):
- Starts around $20/month
- Pricing scales based on list size and features
What You Get:
Deep segmentation, predictive analytics, email/SMS combos, and dynamic content. It’s particularly strong if you need to communicate differently with multiple buyer personas or industries.
Real B2B Use Case:
A SaaS company that sells compliance tools to IT and HR leaders uses Klaviyo to tailor nurture emails based on role, industry, and past engagement—turning their marketing into a personal assistant, not a megaphone.
Good for: Data-driven teams who want deep insight and precise targeting.
Watch out for: Setup time and complexity.
Zapier – The Glue That Connects Your Tools
No, Zapier isn’t a B2B email marketing platform, but it might be the most important tool on this list. It connects your email tool to your CRM, website, lead forms, spreadsheets, and more—without a developer.
What You Get:
Automated workflows (called “Zaps”) like:
- Send a welcome email when someone fills out a Typeform
- Add leads to your CRM and tag them based on product interest
- Notify your team in Slack when someone books a demo
Real B2B Use Case:
A consulting firm uses Zapier to connect Gravity Forms (on their site) to ActiveCampaign, segment leads based on interest, and trigger follow-up emails—all automated, no code required.
Good for: Anyone using multiple tools who wants to automate like a pro.
Watch out for: Some learning curve with advanced logic.
