Mailchimp’s transactional costs $20 for a block of 25,000 emails. That is 80 cents per thousand, which looks competitive against most dedicated providers.<\/p>\n\n\n\n

Your bill will not reflect that figure, because you cannot buy blocks on their own. Transactional Email is an add-on, and the thing it is an add-on to is a paid Mailchimp marketing plan you may have no use for.<\/p>\n\n\n\n

At low volume that second product is not a detail. It is half of what you pay.<\/p>\n\n\n\n

Quick Answer: What Is Mailchimp’s Transactional Cost?<\/h2>\n\n\n\n

From Mailchimp’s Transactional Email pricing page<\/a>, each block is a credit for 25,000 emails, and the per-block rate falls as volume rises:<\/p>\n\n\n\n

Blocks<\/th>Emails per month<\/th>Price per block<\/th>Per 1,000<\/th><\/tr><\/thead>

161+<\/td>4M+<\/td>$10<\/td>$0.40<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Two conditions attach to all of it. Unused emails do not carry over<\/strong> from one month to the next. And per Mailchimp’s own documentation<\/a>, Transactional Email “is a paid add-on to a Standard or Premium monthly Marketing plan”<\/strong> \u2014 the Essentials plan is explicitly not eligible.<\/p>\n\n\n\n

A dedicated IP is available as an optional add-on at $29.95 a month. New users can try a free demo of up to 500 sends to a verified domain.<\/p>\n\n\n\n

How Blocks Behave, and Why That Costs You<\/h2>\n\n\n\n
\"Block
Your effective rate depends entirely on how close you land to a block boundary.<\/figcaption><\/figure>\n\n\n\n

Block pricing is not the same as per-send pricing, and the difference shows up as a sawtooth in your effective rate.<\/p>\n\n\n\n

Because you buy capacity in units of 25,000 and nothing carries over, a month that lands just above a boundary costs the same as a month that fills the block completely.<\/p>\n\n\n\n

# Blocks are 25,000 emails. Unused credits expire monthly.\n\n  25,000 emails  ->  1 block  = $20  ->  $0.80 \/ 1,000\n  26,000 emails  ->  2 blocks = $40  ->  $1.54 \/ 1,000\n  30,000 emails  ->  2 blocks = $40  ->  $1.33 \/ 1,000\n  50,000 emails  ->  2 blocks = $40  ->  $0.80 \/ 1,000\n  51,000 emails  ->  3 blocks = $60  ->  $1.18 \/ 1,000\n\n# Sending 1,000 more than 25,000 costs an extra $20\n# and discards 24,000 unused credits at month end.<\/code><\/pre>\n\n\n\n
So the advertised 80 cents per thousand is the best case<\/em> \u2014 what you pay only when your volume happens to land exactly on a multiple of 25,000. Anywhere else, you are paying for capacity you will not use and cannot bank.<\/p>\n\n\n\n
Common Mistake<\/p>\n\n\n\n
Treating the per-thousand figure as your rate. It is the rate at a full block, and transactional volume rarely cooperates. A product sending around 27,000 emails a month pays for 50,000 every month, and the 23,000 unused credits expire rather than covering next month’s spike. If your volume sits a little above a boundary, the cheapest change available to you is often to send less<\/em> \u2014 which is a strange position for an email provider to put you in.<\/p>\n\n\n\n
The Second Product You Have to Buy<\/h2>\n\n\n\n
\"The
The mandatory Marketing plan is half your bill at 25,000 emails and a rounding error at 500,000.<\/figcaption><\/figure>\n\n\n\n
This is the part that changes the comparison, and it is easy to miss because it sits on a different pricing page.<\/p>\n\n\n\n
Mailchimp Transactional is an add-on to a Standard or Premium Marketing plan. You cannot subscribe to it by itself, and you cannot attach it to Essentials \u2014 Mailchimp’s cheapest paid tier is not eligible. So the floor for any Transactional setup is a Standard Marketing plan plus at least one block.<\/p>\n\n\n\n
Mailchimp’s Marketing pricing page<\/a> lists Standard from $20 a month, though that figure is an introductory rate for the first twelve months and scales with your contact count \u2014 so treat it as an illustration and get your own number before comparing anything.<\/p>\n\n\n\n
Using that $20 as the illustration, here is what the two products do to your effective rate:<\/p>\n\n\n\n
Monthly emails<\/th>Blocks<\/th>+ Marketing plan<\/th>Blocks alone<\/th>True rate<\/th><\/tr><\/thead>
25,000<\/td>$20<\/td>$40<\/td>$0.80\/1,000<\/td>$1.60\/1,000<\/strong><\/td><\/tr>
50,000<\/td>$40<\/td>$60<\/td>$0.80\/1,000<\/td>$1.20\/1,000<\/td><\/tr>

At 25,000 emails the Marketing plan is 50% of the bill<\/strong>, and your true rate is double the advertised one. At 100,000 it is 20%. By 500,000 it is under 5% and the advertised rate is close to honest.<\/p>\n\n\n\n
That is the shape of this pricing model: structurally hostile to small senders, and perfectly reasonable at scale.<\/strong> Which is a legitimate commercial position \u2014 it just means the published per-thousand figure describes a customer you may not be.<\/p>\n\n\n\n
