If you're using Amazon SES and your website is HSTS (HTTP Strict Transport Security) compliant, you must set up an HTTPS tracking domain. For more information, read Setting Up HTTPS links for click tracking.
On the Settings > Mail Domains page, there are two sections: Tracking Domains and Sending Domains.
Tracking domains are used to white label links in your campaigns and for click tracking.
- Only one tracking domain can be used for each sending domain.
- When hovering over the links in your campaigns, users will see this domain.
- When a user clicks on a link within your campaign, we will set four cookies on the tracking domain. More information can be found in the Purchase and revenue tracking guide.
Adding a tracking domain
To add a tracking domain:
Ensure first that you have registered the tracking domain CNAME (DNS) record with a value of
In Settings > Mail Domains, under Tracking Domains, enter the tracking domain that you'd like to use for white labeling links and click tracking.
Click on Add Tracking Domain.
Check the Default box if you would like this to be the default tracking domain for each of the sending domains that you enter.
If your website requires HTTPS and you completed the associated setup, notify your customer success manager to toggle on the HTTPS button.
Allow 24 hours for the domain to be verified.
If your website is HSTS compliant and you are using a CloudFront
distribution, the CNAME is shown under Tracking Domains as
links.iterable.com. This occurs through double forwarding:
links.YOUR_DOMAIN.com CNAME to
[CloudFront Distribution URL] CNAME to
Use sending domains to set the domain from which you'd like to send email. We recommend that you add and verify each sending domain associated with the senders you list in Settings > Senders.
To add the sending domain, follow these instructions:
Add the sending domain to your ESP setup (your account manager can help with this).
Add the associated DNS record(s).
Navigate to Settings > Mail Domains.
Under Sending Domains, enter the sending domain (i.e.
mycompany.com) that you'll be using with your ESP account.
Click Add Sending Domain.
If you do not want to use the default tracking domain for a particular sending domain, click Edit on the right side, then select a different tracking domain from the associated dropdown, under the Tracking Domain column.
Notify your account manager to verify the sending domain.
