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
- Head to Custom SMTP Settings in the Email & Actions section of your Account Settings.
- Add in your Mandrill settings (you can find those here):
When you save your settings, we’ll start sending emails through your Mandrill account.
Ensure that your unsubscribe link works
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.
Point Mandrill’s webhooks at Customer.io
Go to the Mandrill webhooks page and click “Add a Webhook”.
From there, check these events:
- Message Is Sent
- Message Is Bounced
- Message Is Marked As Spam
- Message Is Rejected
- Message Is Delayed
- Message Is Soft-Bounced
In the “Post To URL” field, enter:
Click Create Webhook to save.
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!
