Choosing the right email marketing software for B2B shapes how well you can segment your audience, automate follow-ups, and track what’s actually converting. This list covers 9 platforms worth considering in 2026, with what each one does best and current pricing structure so you can compare on more than just a feature list.
9 best email marketing software for B2B
Brevo (formerly Sendinblue)
Brevo, renamed from Sendinblue in 2023, is a strong B2B contender with SMS marketing, chat, and built-in CRM tools alongside email. What makes Brevo distinct from most competitors is its pricing model: plans are based on how many emails you send per month, not how many contacts you store, and every plan including the free tier allows unlimited contacts. The free plan covers 300 emails a day; paid plans with automation start around $18/month depending on your sending volume. This structure favors businesses with large contact lists who don’t email everyone constantly.
Omnisend
Omnisend leans into multichannel marketing, combining email with SMS and push notifications in the same automated workflows. Its segmentation and analytics help you personalize messages and track engagement, and pricing starts at $16/month for 500 contacts, with a limited free plan available. It’s strongest for businesses that want email and other channels working together rather than managed separately.
Benchmark Email
Benchmark Email pairs intuitive segmentation with detailed analytics to help refine campaigns over time. Its standout feature is built-in surveys and polls, useful for gathering audience insight directly rather than inferring it from open rates alone. Pricing starts around $13.99/month; check Benchmark’s current pricing page for exact tiers since plans are periodically adjusted.
SendX
SendX offers a genuinely user-friendly interface with a flat pricing structure, making costs predictable as you grow rather than scaling unpredictably with contacts. Standout features include 1-click resend to unopened emails and geo-tracking, both useful for squeezing more engagement out of a single campaign. Entry pricing starts around $7.49 to $9.99/month depending on current promotions, making it one of the more budget-friendly options here.
Mailchimp
Mailchimp remains a familiar name in B2B email marketing, offering flexible segmentation plus landing pages, social media ads, and an easy email builder beyond core sending. Its free plan is fairly limited (roughly 500 contacts, 1,000 emails/month), and pricing climbs noticeably as your contact list grows, so budget for that scaling rather than assuming entry pricing holds as you expand.
Constant Contact
Constant Contact adds event management tools and integrated e-commerce functionality on top of standard segmentation and analytics, useful if your B2B outreach includes webinars or in-person events. There’s no free plan, but pricing starts around $20/month, positioning it as a mid-range option with genuinely differentiated features rather than just email basics.
HubSpot
HubSpot bundles email marketing with CRM, content management, and broader inbound marketing tools, making it the most comprehensive platform on this list if you want marketing and sales data unified in one place. Its Starter tier is more accessible than older pricing suggested (often cited around $20/month per seat), but costs climb quickly once you need Professional-tier automation and reporting, so map your actual needs against the tier that unlocks them before committing.
Campaign Monitor
Campaign Monitor’s dynamic content features make it a solid choice for businesses that want real personalization without a steep setup process, backed by solid segmentation and analytics. Pricing starts around $9/month for entry-level sending volumes.
AWeber
AWeber is one of the longest-running platforms in this space, with reliable segmentation, analytics, autoresponders, and integrations with common business tools. It tends to sit on the pricier end compared to newer entrants like Brevo or SendX, with entry pricing around $19.99/month, but its ease of use and support quality make it a reasonable choice for small to midsize B2B teams that value stability over cutting-edge automation.

Conclusion
Each of these platforms brings a different strength to B2B email marketing, whether that’s Brevo’s send-based pricing, Omnisend’s multichannel workflows, or HubSpot’s unified CRM and marketing data. The best choice depends on your contact list size, how much you plan to automate, and whether you need email to stand alone or integrate with a broader marketing and sales stack.
