If your links in your campaigns aren't working, here are a few things to check.
Typo in link
Missing link reference
|This is the #1 reason most links aren't working. Links use the markdown formatting of [Link display text](http://linkURL.com)|
|Google Analytics problems||If you have Google Analytics integrated, it will add a whole bunch of extra parameters to your links, to look something like this:|
Copy only the first part, up to the ?, and paste that into a browser. If it works that way, there's a problem with your Google Analytics set up.
See more info on setting up the Google Analytics addon.
It's very smart to give all links a quick test before you send the email to others. You can do this in the Preview screen, and by sending yourself a test email.
