Email campaign tracking is pretty important. If you’re paying top dollar and investing your own time and effort into gathering an email list, writing good sales copy, and ensuring deliverability, then you want to get as much for your effort as possible.
If you’re just linking back to your site using regular URLs, consider using LinkTrack URLs instead. That way you can get an idea of what your readers are most interested in and how they’re reacting to your messages.
Once you know that, you can tailor your campaign better achieve your goals.
