Before the Engagement Tracking or Custom Bounce Domain features can be used, a subdomain must be configured.
To configure a custom domain for example.com, such as email.example.com, the following CNAME record would need to be configured in DNS:
email.example.com CNAME tracking.socketlabs.com
This record tells DNS systems that when looking up email.example.com, to redirect and actually look at the records for tracking.socketlabs.com.
These records need to be configured wherever your domain hosts its DNS.
Please be aware that modifications to DNS settings can take up to 48 hours to propagate, though often this process takes minutes.
DO NOT create 3 CNAME records for the Custom Bounce Domain feature!
The following suggestion is for if you already have a CNAME record created in your DNS that uses email as the sub-domain.
You can establish multiple CNAME records to have unique values in your URLs when compared to your bounce address. For example, you could create both links.example.com and bounces.example.com by setting the configurations as:
links.example.com CNAME tracking.socketlabs.com
bounces.example.com CNAME tracking.socketlabs.com
Enabling Custom Bounce in SocketLabs
Once the proper CNAME(s) have been configured in the organizational domain's DNS settings, the features can be configured from the SocketLabs Control Panel by clicking on Configuration > Advanced Authentication. If validation is successful, the settings page will allow the Engagement Tracking or Custom Bounce Domain feature to be enabled. If the domain's CNAME cannot be validated, this feature cannot be enabled.
