Use your Mandrill Account to Send Customer.io Email

Customer.io supports using your own Mandrill account to send email with zero loss in functionality. To do this, there are two places you’ll need to change settings:

1. In Customer.io

Configure your SMTP settings

  1. Head to Custom SMTP Settings in the Email & Actions section of your Account Settings.
  2. Add in your Mandrill settings (you can find those here):

Adding custom SMTP settings

When you save your settings, we’ll start sending emails through your Mandrill account.

If you’re using the Customer.io unsubscribe, then everything will continue to work. If you’d prefer to use the Mandrill-provided unsubscribe you’ll want to add their unsubscribe link to your emails or layouts. You’ll need to make one change to ensure it processes. Also, add class=”untracked” to the link, like this:

<a href="*|UNSUB:http://mywebsite.com/unsub|*" class="untracked">Unsubscribe.</a>

Please note that if you’re using the Mandrill unsubscribe, those unsubscribes will not be tracked in Customer.io. They’ll only be tracked in Mandrill.

2. Mandrill

Point Mandrill’s webhooks at Customer.io

Success!

Your account is now set up to send email through Mandrill. If you have any questions or feedback about setting this up, just get in touch and we’ll be happy to help!
