Email marketing platform with automation. Free for 500 contacts, then contact-based pricing creates a gotcha — you pay for unsubscribed and inactive contacts too.

Hidden Fees & Gotchas

What the pricing page doesn't tell you

Unsubscribed Contacts Count

Mailchimp counts unsubscribed and non-subscribed contacts toward your billing limit. A list of 10K with 3K unsubscribes still bills for 10K contacts. Must manually archive to reduce count.

Trigger: unsubscribedContacts > 0

+$30

/monthly

Steep Contact Tier Scaling

Pricing jumps dramatically: 500 contacts = $13.99/mo, 2,500 = $45/mo, 10K = $100/mo, 50K = $350/mo. Each tier increase is non-linear and much steeper than competitors.

Trigger: contacts > 2500

+$50

/monthly

Pay-As-You-Go Email Credits

Over-limit sends cost extra as email credits. Standard plan allows 12x your contact limit per month. Exceeding requires purchasing credit blocks at roughly $0.02-$0.03 per email.

Trigger: emailSends > limit

Advanced Automation Paywall

Free and Essentials include only basic automations. Customer journeys with branching, A/B testing, and advanced triggers require Standard ($13.99+/mo) or Premium ($350+/mo).

About Mailchimp Pricing

Mailchimp's free plan allows 500 contacts and 1,000 sends/mo. Standard at $13.99/mo for 500 contacts sounds reasonable, but pricing scales steeply with contacts. At 10K contacts, Standard costs $100/mo. At 50K, $350/mo. Worse: unsubscribed contacts count toward your limit unless you manually archive them.
