What is Mandrill?

Mandrill is an email infrastructure service offered as an add-on for MailChimp that you can use to send personalized, one-to-one e-commerce emails, or automated transactional emails.

How Does it Work?

With Mandrill, you can send emails through the Mandrill API or SMTP integration. If you're already sending transactional emails for your website through SMTP, you can typically change your SMTP credentials to Mandrill's and begin sending immediately. With the Mandrill API, you can send emails, get information about your account, and view or parse reporting data in your own app or system.

How Much Does it Cost?

We offer two pricing plans: a free trial with 2,000 email credits and a paid monthly plan. Free trial plan users need to upgrade to a paid monthly plan once they use the 2,000 free email credits.

If you're on a paid monthly plan, you can choose the number of emails that you'll purchase each month. We built discounts into our payment structure, so your per-email pricing automatically decreases as you send more email. Calculate your monthly costs and view example volumes on our pricing page.

Do You Offer a Free Trial or Demo?

Yes. We offer a free trial account with 2,000 email credits. Free trial plan users need to upgrade to a paid monthly plan once they use the 2,000 free email credits to continue sending email through Mandrill.

Mandrill is designed to be flexible and customized depending on your existing framework. The best way to demo Mandrill with different frameworks or integrations is to sign up for a free trial account and begin sending email. Use Mandrill's test mode to generate emails using our API or SMTP integration and simulate bounces, unsubscribes, and spam complaints without actually sending live email.



Starting March 16, 2016, new Mandrill users will be required to have a paid monthly MailChimp account and to verify ownership all sending domains.

Existing Mandrill accounts will have until April 27 to merge their Mandrill account with a paid MailChimp account. Any Mandrill accounts not merged by this deadline will be disabled.
