Best Mailchimp alternatives for 2026
Mailchimp's price hikes since the Intuit acquisition in 2021 have been the slowest-burn migration story in marketing software. The Standard plan went from $14.99 to $20 to $30 over four years, and the Essentials cap on contacts now triggers an upgrade where it used to bundle. Most people leaving Mailchimp in 2026 cite three things: the cost-per-contact math gets brutal past 5,000 subscribers, the automation builder feels stuck in 2018 compared to Klaviyo or Customer.io, and the AI features (subject line generator, send-time optimization) feel bolted-on rather than integrated. If you're paying $80 to $300 a month on Mailchimp and wondering if you're overpaying, you probably are. Here are six alternatives worth a look.
1. Klaviyo
Pricing: free up to 250 contacts, then $45/mo at 1,000 contacts, $150/mo at 5,000, $400/mo at 15,000 in 2026. What it does better than Mailchimp: ecommerce automation is a different category. Klaviyo's Shopify integration writes purchase data into the contact profile and lets you build flows on real ecommerce signals (browse abandonment, predicted churn, customer lifetime value). The AI features (predicted gender, predicted CLV, optimal send time) are baked in, not bolted on. What it does worse: pricing scales harder past 50,000 contacts, and if you're not on Shopify, BigCommerce, or Magento, half the value evaporates. Decision rule: pick Klaviyo if you run an ecommerce store, period.
2. Constant Contact
Pricing: $12/mo Lite (500 contacts), $35/mo Standard (500 contacts), $80/mo Premium in 2026. What it does better: phone support is genuinely good. If you've ever sat on Mailchimp's chatbot waiting 4 hours for a human, Constant Contact will pick up in under 5 minutes. The event marketing features (RSVP, ticket sales) are stronger. What it does worse: automation builder is weaker than Mailchimp's, and the email design templates feel dated. Decision rule: pick Constant Contact if you run events (workshops, classes, fundraisers) and value live phone support over feature depth.
3. ConvertKit (now Kit)
Pricing: free up to 10,000 subscribers, $25/mo Creator, $50/mo Creator Pro at 1,000 subscribers in 2026. What it does better: built for creators, podcasters, and newsletter operators. The landing page builder, the visual automation, the broadcasts-vs-sequences distinction are all cleaner than Mailchimp for content businesses. Tagging instead of lists is the right model for newsletter readers. What it does worse: ecommerce features are thin. The deliverability is good but not as good as Mailchimp's reputation gives them. Decision rule: pick Kit if you're a writer, podcaster, course creator, or run a newsletter.
4. Brevo (formerly Sendinblue)
Pricing: free up to 300 emails/day, $25/mo Starter (20,000 emails), $65/mo Business in 2026. Charges by emails sent, not by contacts stored. What it does better: the pricing model is the headline. If you have 80,000 contacts but only email 20,000 a month, Brevo costs roughly half of what Mailchimp would. SMS marketing is built in (not Mailchimp's add-on). What it does worse: deliverability is uneven. I've seen Brevo land in Promotions tab where Mailchimp landed in Primary, on identical content. Decision rule: pick Brevo if your contact list is 5x larger than your active sender base.
5. HubSpot Marketing Hub
Pricing: free up to 1,000 marketing contacts, $20/mo Starter, $890/mo Professional in 2026. What it does better: the CRM integration is the entire point. If your sales team and marketing team share contact data, HubSpot eliminates the awkward Mailchimp-to-Salesforce sync. AI features are deeper, especially predictive lead scoring. What it does worse: Marketing Hub Pro at $890/mo is roughly 6x what comparable Mailchimp would cost. The Starter tier is fine for under 5,000 contacts, but past that, the price escalator is steep. Decision rule: pick HubSpot if you already use HubSpot CRM. Don't pick it for email alone.
6. MailerLite
Pricing: free up to 1,000 subscribers, $15/mo Growing Business (1,000 subs), $32/mo Advanced in 2026. What it does better: the cleanest interface in this list. The drag-and-drop email builder feels modern. Pricing is roughly 30 to 40% cheaper than Mailchimp at every tier. What it does worse: smaller integration ecosystem (Mailchimp has roughly 4x the third-party connectors). Reporting is shallower. Decision rule: pick MailerLite if you want a Mailchimp-equivalent at a lower price and you don't need exotic integrations.

Who should stay on Mailchimp
If you're under 2,000 contacts, send fewer than 4 campaigns a month, and you've already built your templates and automations on Mailchimp, the switching cost (40 to 80 hours of rebuild plus deliverability ramp) is rarely worth it. The cost difference at that volume is $20 to $50/mo. Stay where you are.
If you're using Mailchimp's CRM-lite features (audiences, tagging, purchase data) and they're working, Mailchimp at the Standard tier is honestly fine. The complaints about Mailchimp are mostly about the Premium tier and the post-50,000-contact pricing, not the basic plans.
FAQ
How long does a Mailchimp migration take? 30 to 60 hours for a working email program with 5 to 12 active automations and 8 to 15 templates. Plan a 30-day overlap where both systems run in parallel before you cut DNS.
Will my deliverability tank when I switch? Briefly, yes. Most ESPs need a 14 to 30 day warm-up where you start with your most engaged segment and work outward. Skipping the warm-up is the most common reason post-migration deliverability drops.
Should I keep Mailchimp running while I transition? Yes, for 30 days minimum. Run new campaigns on the new platform, keep automations running on Mailchimp until the migration is complete, then sunset Mailchimp on day 30.
Does Mailchimp's free plan still exist in 2026? Yes, capped at 500 contacts and 1,000 sends per month. Most businesses outgrow it within 90 days.
Decision rule
Ecommerce on Shopify: Klaviyo. Newsletter or creator business: Kit. Cost-conscious general business: MailerLite. Already on HubSpot CRM: HubSpot Marketing. Large list with low send volume: Brevo. Heavy event marketing with phone support need: Constant Contact.
