About Additional Charges

Our monthly plans come with a set amount of contact storage and email sends per pricing tier. If your total contact count or send count ever exceeds the limit of your plan, we won’t interrupt your service. Instead, you’ll see an additional charge on your monthly bill.

In this article, you’ll learn about additional charges.


Additional charges are part of Mailchimp’s new pricing model, introduced on May 15, 2019. If you had a paid Mailchimp account before the new pricing model was introduced, you have a legacy pricing plan, and you won’t be affected by these changes.

How the Additional Charge Works

When you choose a paid monthly plan, you’ll decide how many contacts you want to store in Mailchimp. The number you choose determines your pricing tier, and your monthly send limit. You can change your audience size anytime.

Sometimes, your audience might grow more than you expected, or you might send more emails than usual in a month. If you go over the contact or send limit for your tier, we’ll charge you for an extra, smaller set of contacts, called an add-on contact block. If you exceed your limit by more contacts or emails than what is included in one add-on block, the additional charge will include multiple add-on blocks. This charge is assessed month-by-month, based on your billing cycle.

The price of the add-on contact block, and the number of contacts and email sends it includes, depends on your plan and pricing tier. If you’re logged into Mailchimp and you set the audience size for your plan, we’ll tell you how many contacts and email sends are included, as well as the price and size of add-on contact blocks (with additional email sends).


For example, if you have the Standard plan, the email send limit is 12 times your audience size. This formula also applies to add-on contact blocks, so one block of 1,000 additional contacts includes 12,000 additional email sends.

Next Steps

If you see an additional charge on your bill, you’ll still be responsible for the additional charge shown on that bill, but you can increase your audience size to the appropriate pricing tier to avoid the charge on your next bill.

If you don't want to increase your audience size, here are a couple of alternative options.

  • Archive unengaged contacts
    Use segmentation to identify which contacts aren't interacting with your campaigns or making purchases in your store. Then, archive those contacts to reduce your number of chargeable contacts.

  • Send more targeted campaigns
    Instead of sending every email to all of the subscribed contacts in your audience, send targeted content to smaller segments.
