Relative URL Site links in CBSubs Mailer emails

I have inserted links back to the website in my CBSubs Mailer emails, but they don't work. I only use relative URLs for the links. This method works for all other automatically generated emails throughout Joomla, but does not seem to work properly from certain automated emails from Community Builder or from CB Subs (such as CBSubs Mailer emails). Is there something we can do to make relative URL links work properly when included in these auto generated emails?

We do not process emails for URLs. You should not be using relative URLs in any emails. Always use live path URLs in emails to ensure they'll go where you need them to. You can use [cb:config param="live_site" /] to insert the domain name with a substitution as well if you want to automate that part.

Adding [cb:config param="live_site" /] solved the problem.
