Paid plans start at $20/mo.
The Free Demo allows up to 500 test sends to verified domains, but it is not a free production plan. To send production email, you need an active Mailchimp Standard or Premium account and pay monthly per 25,000-email block. The listed rate starts at $20 per block for 1 to 20 blocks, then drops across higher-volume tiers. Unused emails do not roll over, and sending stops at the limit unless blocks auto-purchase.

02What the plan grid doesn't tell you
Mailchimp account prerequisite

Block auto-purchases
Sending stops at the limit unless blocks auto-purchase. Check the setting and resulting charges before enabling it.
Dedicated IP
A dedicated IP is listed at $29.95 per month, in addition to email blocks.
Transactional SMS credits
SMS uses SMS marketing credits, but the credit price is not published. Confirm the cost before adding SMS to your workload.
03Which plan should you buy?
| If you are… | Get | Why |
|---|---|---|
| Testing on a verified domain | Free Demo | Allows up to 500 test sends; it is not a production tier. |
| Small production workload | 1 to 20 blocks | Covers 1 to 500,000 emails per month at $20 per 25,000-email block. |
| Higher-volume production | 21 to 40 blocks | Covers 500,000 to 1 million emails per month at $18 per block. |
04Is Mailchimp Transactional Email worth the money?
The block pricing is straightforward to estimate when monthly volume is predictable, and the listed per-block rate falls at higher tiers. But this is not an independent free-tier option: the demo is capped at 500 sends, and production requires an active Mailchimp Standard or Premium account. Factor that account, any dedicated IP, and SMS credits into the total. The Free Demo is enough for basic integration checks; production teams should confirm block auto-purchases and account pricing before committing.
