HawkOpen or Mailtrack? A comparison without the marketing

Mailtrack (now Mailsuite) is a popular email tracking extension for Gmail, with millions of installs and its own document and signature features. HawkOpen, a Mailtrack alternative, is newer and smaller. It differs by showing a category and rule code for every open and click, by also working over IMAP and in Outlook on the web, and by plainly calling its signature a simple signature.
