Paid plans start at $20/mo.
Mailchimp Transactional Email starts at $20 per month for each 25,000-email block, with lower per-block rates at higher monthly volumes. The free demo covers up to 500 sends to a verified domain; it is not an ongoing free plan. You also need an active Mailchimp Standard or Premium account, whose price is not included here. Blocks expire monthly, and sending stops at your allowance unless you enable automatic block purchases. Annual pricing is not published.

02What the plan grid doesn't tell you
Mailchimp account required
You must have an active Mailchimp Standard or Premium account; its subscription price is separate and not listed here.
Unused volume expires
Unused emails do not roll over, so monthly volume swings can leave paid capacity unused.
Sending cap behavior
At your limit, sending stops unless blocks are set to auto-purchase. The pricing lists no per-email overage fee.
Optional services
A dedicated IP is $29.95 per month. Transactional SMS uses SMS marketing credits, but its price is not published.
03Which plan should you buy?
| If you are… | Get | Why |
|---|---|---|
| Testing a verified domain | Free Demo | Up to 500 free sends; a verified domain is required, and this is demo mode rather than an ongoing free plan. |
| Up to 500,000 emails monthly | 1 to 20 blocks | Costs $20 per 25,000-email block monthly for 1–20 blocks; unused email allowance does not roll over. |
| More than 4 million monthly | 161+ blocks | Costs $10 per 25,000-email block monthly at 161+ blocks; sending stops at the limit unless blocks auto-purchase. |
04Is Mailchimp Transactional Email worth the money?
Mailchimp Transactional Email makes the most financial sense when your team already pays for Mailchimp Standard or Premium and wants transactional messages alongside that account. It includes API and SMTP sending, templates, inbound processing, webhooks, and deliverability tools, but the add-on still charges by monthly volume blocks. For teams comparing only low-cost email delivery, the $20 entry block plus the required Mailchimp account makes it less compelling. SMS pricing is also unpublished.
Mailchimp Transactional Email pricing FAQ

Is there a free plan or trial?
There is no free ongoing plan. Free Demo allows up to 500 sends to a verified domain for testing. For production use, Mailchimp Transactional Email is a paid add-on for an active Standard or Premium account. The demo is not a substitute for a monthly sending block.
What happens when I reach my email limit?
Unused emails do not roll over from month to month. If you reach the block limit, sending stops unless automatic block purchases are enabled. The pricing lists no per-email overage fee; extra volume is handled through additional blocks.
