The questions where ChatGPT currently names Mailgun.
If you specifically want a Mailchimp alternative with “unlimited sends”, there are a few strong options in 2026—but they differ a lot in pricing model and what “unlimited” really means (true unlimited vs. high caps vs. unlimited contacts).
Here are the best ones:
Unlimited email sends on paid plans (and generous free tier)
Built for newsletters and audience growth
Very clean writing + publishing workflow
Monetization tools (ads, subscriptions)
Best for: creators, newsletters, content brands Limitation: less “marketing automation” than Mailchimp
Unlimited contacts on all plans
Email sending is volume-based (not per contact), which effectively gives you “unlimited scaling”
Free plan includes daily sending limits (~300 emails/day)
Strong automation + CRM features
Best for: Shopify stores, D2C brands, transactional + marketing emails Why people switch: you don’t get punished for list size
Free plan: up to ~12,000 emails/month
Paid plans: very generous sending limits
Includes automations, landing pages, and forms
Not technically unlimited sends, but very high for the price
Best for: small businesses wanting simplicity + automation
Not unlimited sends on pricing sheet, but very high limits per plan
Industry-leading automation builder (email + CRM + segmentation)
Expensive compared to others, but powerful
Best for: serious lifecycle marketing and funnels
Unlimited emails
Unlimited contacts
You only pay for SMTP (sending service like Mailgun/Postmark)
Best for: technical teams who want full control + lowest cost at scale
