Mailchimp in short
Mailchimp is email marketing's biggest name, and its billing is its most-quoted product: every contact counts toward your paid tier — subscribed, non-subscribed and unsubscribed alike — until you archive them one by one. Since Intuit's $12B acquisition in 2021, prices have risen roughly 20–30%, with a further 11–13% in April 2026 pushing Premium past $375/mo, while the free plan shrank from 2,000 contacts to 250. Exceed a contact or send limit and Mailchimp adds paid email blocks to your next invoice without an upgrade prompt, at overage rates it doesn't publish.
Verdict: The builder is excellent; the billing math is adversarial. You keep paying for people who can no longer receive your email, and the price you're quoted is the price this month — not the price at renewal.
Frequently asked questions
Does Mailchimp charge for unsubscribed contacts?
Yes. Subscribed, non-subscribed and unsubscribed contacts all count toward your contact limit; only cleaned, pending, deleted and archived contacts don't. To stop paying for a contact you must archive or delete them by hand.
What happens when I exceed my contact or send limit?
Mailchimp automatically adds extra email blocks and bills them on your next invoice — users report no upgrade prompt or warning, and the exact overage pricing isn't publicly listed.
Why do people call Mailchimp expensive?
Prices have risen roughly 20–30% since the 2021 Intuit acquisition, with another 11–13% in April 2026 pushing Premium past $375/mo, while the free plan dropped from 2,000 contacts to 250. Reviews describe bills jumping exactly at tier boundaries as lists grow.
Is Mailchimp an email API?
It has a marketing API but it is a campaign platform first. If you need transactional sending from code — and inbound replies through the same interface — developer-first email APIs do that part better, and price by emails sent rather than by contacts stored.
Can I get my money back after cancelling?
Cancellation complaints are a genre of their own: reviewers report being charged after cancelling, some re-subscribed without asking. Read renewal terms as something to archive contacts against, not trust.
When is Mailchimp still the right buy?
When a marketing team lives in journeys and segments all day and budgets for premium tooling. The complaints are about the bill — not about what the builder can do.
