Features & Capabilities

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.

Prior to updating my laptop recently (which included W7 to W10) ReadNotify worked well. Since the upgrade however Thunderbird refuses to add the ReadNotify.com suffix to my outgoing emails. Contact with ReadNotify has narrowed this down to Thunderbird seeming to ignore the presence of ReadNotify on my computer. Despite reinstalling Thunderbird at least twice the prompt to allow the ReadNotify add-on fails to appear and the list of add-ons in Thunderbird does not include ReadNotify or RN5 despite the software showing it as installed and active on my computer. Tracking works if I manually add .ReadNotify.com to outgoing email addresses but it won't add automatically as it should. Has anybody got any suggestions?

Is Readnotify.com Web Plugin Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Readnotify.com Web Plugin requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk impact analysis details
  • Critical Request access to the following domains: google.com, yahoo.com, live.com, 0.1, vradd.com
  • High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****
Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Readnotify.com Web Plugin has earned a fairly good reputation and likely can be trusted.
