How do the tracking links in MailMerge365 work?
When you activate "Click tracking" in MailMerge365 the links in your email are replaced with unique links for each recipient.
They will usually have the format
https://xxx.tlink.re/c/<randomstring>/l/<randomstring>

There are some exceptions to click tracking which we've summarized here.
