A custom tracking domain is a dedicated subdomain that is used specifically for tracking the performance of cold email campaigns. It is set up to track user interactions like email opens, clicks on links within the emails.
Having a custom tracking domain will improve your deliverability and help you stay off blacklists.
Open and click trackings in Manyreach are optional, but if you plan to track opens and clicks it's crucial to set up a custom tracking domain. It is advised to set up a matching tracking domain for each sending domain.
If you have a sender john@getbusiness.com, then your sending domain is getbusiness.com. Custom tracking domain is then a subdomain of your sending domain - link.getbusiness.com.
Before you setup a custom tracking domain in Manyreach, you need to go to your domain hosting provider - place where you bought domain or where you have access to the DNS settings.
Once you are there create a CNAME record that points to link.sndprs.com
Record type: CNAME
Host: link.{yourdomain.com}
Answer: link.sndprs.com
TTL: as is by default
After you create a CNAME wait a few minutes for new records to propagate. This time depends on your hosting provider. You can check if the record is already live at https://mxtoolbox.com/CNAMELookup.aspx. If you see a screen like below it means the subdomain is ready to be added to Manyreach.
