Readnotify.com Web Plugin автор VRADD Developer

This plugin adds new options into your email "compose" form, which lets you track your email (find out when your email gets read), as well as giving you multiple other options to choose from - including self-destructing emails, language translation (send in one language, and it comes out in a different one you choose), certified emails, the ability to delete emails after you've sent them, and more.

This is a companion extender for our ActiveTracker plugin (download from http://www.readnotify.com/readnotify/plugin.asp ) - which adds all those features and more, into other email programs you use (not just Firefox webmail).

ReadNotify is the worlds most trusted email tracking service, now in our 15th year of business, with millions of happy customers.
