Best Mailchimp Alternatives for 2026
Why teams leave Mailchimp, what they switch to, and how the total cost of ownership compares.
Why teams leave Mailchimp
Mailchimp counts ALL contacts toward your billing tier — subscribed, unsubscribed, and non-opted-in. Unsubscribed contacts remain billable unless you manually archive them. A company with 10,000 'contacts' might have 3,000 active subscribers but pays the 10,000-tier rate.
Mailchimp deprecated the Classic Automation Builder in June 2025, pushing multi-step automations exclusively into the Standard plan ($20/mo minimum). Organizations running basic welcome sequences on Free or Essentials were forced to upgrade overnight.
When you exceed your contact or send limit, Mailchimp automatically adds extra email blocks and charges your next invoice — without an upgrade prompt or warning. The exact overage pricing isn't publicly listed, making costs impossible to predict.
Since Intuit acquired Mailchimp for $12B in 2021, pricing has increased 20-30% across paid tiers (Essentials from $9 to $13, Standard from $14 to $20), the free plan was gutted from 2,000 contacts to 250 — an 87.5% reduction — and another 11-13% increase hits April 2026.
What teams are switching to
Mailchimp's estimated TCO is $10,980/yr for a 5-person team. Here are the alternatives teams are using instead.
Brevo
Free (300 emails/day), Starter $9/mo, Business $18/mo
Charges by emails sent, not contacts stored. Unlimited contacts on all plans including free. Includes transactional email, SMS, and WhatsApp in one platform. A 50,000-contact list sending 50K emails/mo costs ~$35/mo vs Mailchimp's $450+.
Kit (formerly ConvertKit)
Free (10K subscribers), Creator $39/mo
Creator-focused with visual automation builder on all paid plans. Free plan supports up to 10,000 subscribers — 40x Mailchimp's free tier. No charge for unsubscribed contacts.
Loops
Free (1K contacts), $49/mo (5K contacts, unlimited sends)
Built for SaaS companies. One flat tier with all features — no feature gating at all. Includes marketing, transactional, and product emails in one platform. Unlimited sends on all paid plans.

Klaviyo
$20/seat/month
