If you have Primailer installed on email.a.com and you send campaigns, all your url links will start with http://email.a.com and this is fine for most of the cases, but what if you want to handle emailing for the b.com domain?
In this case, you will have to either install primailer in a subdomain for b.com domain like email.b.com or you can still use the install from email.a.com but use a tracking domain for b.com domain.
A tracking domain is simply a CNAME(DNS Record).
In our case, we define a cname for the b.com domain, namely email.b.com that will point to email.a.com subdomain.
Once we do this, propagation can take up to 48 hours, so after 48 hours, we can go in the backend of primailer website and add a new tracking domain, the email.b.com domain. Once we did this, to check if everything works properly, we have to access http://email.b.com and we should get the same page that we get when accessing http://email.a.com. If it’s not showing the same page, then you don’t use a dedicated ip address for a.com domain and you should.
Now, our tracking domain is in place, all we have to do si to associate it with a delivery server, and all emails that will be sent via that delivery server will change all the links from email.a.com into email.b.com.
Step 1: Go to “Tracking Domain” in Domains
Step 2: Click on Create new, to create a new tracking domain
Step 3: Fill the details in Create new tracking domain section:
Click on save changes and your tracking domain has been set up.
Please note that because of the way DNS servers work, you need to add a subdomain like tracking.your-domain.com as a DNS CNAME record and point it to app.primailer.com!
