Purchase Top-Off Emails for Mailchimp Transactional
Copied
Mailchimp Transactional is a powerful delivery API service by Mailchimp that allows you to send e-commerce notifications and automated transactional email and SMS messages. Mailchimp Transactional plans come in a set number of email blocks automatically purchased each month. For months when you send more emails than usual, you can purchase top-off emails for your Mailchimp Transactional plan.
In this article, you’ll learn about top-off email settings and how to purchase top-off emails for Mailchimp Transactional.
How it works
When you add Mailchimp Transactional to your account, you’ll select the number of email blocks to purchase at the beginning of each monthly billing cycle. Top-off emails can be purchased anytime to help adjust for individual months with extra sending. Like regular monthly blocks, top-off emails come in blocks of 25,000 and expire at the end of your billing cycle.
If you’re purchasing top-off emails every month, it may be helpful to change your Mailchimp Transactional plan to increase the number of blocks automatically purchased each month.
Note
Transactional SMS uses the same SMS credits as SMS Marketing. You can purchase additional SMS credits as needed throughout your billing cycle from the SMS overview page or the SMS settings page.

When making a selection, keep in mind that sending will stop if your emails run out, and unused top-off emails expire at the end of the billing cycle.
