Include Subjects in Your Email Links
Using subjects in email links
is a great way to track emails, and so you can automatically have reference
to what people are emailing you about. You can also use the subject line
as an automatic filter, and send everything with that subject line to
a certain email folder.
It is also great to include
your site name in the subject so people know what the response is at first
glance, when your reply enters their in box.
