You can verify that a link is going to be tracked by hovering over the hyperlinked URL or text and seeing that the destination includes "https://t.yesware.com/tl.....".

As a best practice, we recommend naming your links rather than leaving them as a URL. This reduces the chance that the rest of message gets flagged as spam.

Link tracking creates a special link in place of any URL you’ve included in your email.  If the recipient clicks on the tracked link, our server gets pinged with the IP address so we can give you relevant information about the recipient like where they opened the email, when they opened it and even what device they used to read it.
