Boomerang E-Mail is an Add-on for the Thunderbird E-Mail-Client and is based on the Boomerang e-Mail algorithm (patent pending).
It provides functionality to send a certain e-mail (including attachments) to several recipients one after the other and not just all at once. Using this functionality each recipient can make changes to the attached documents and e-mail and then send the e-mail, with one click, to the next recipient in the list until, at last, the e-mail is returned to the original sender with all the review comments appended to the original email and attachments.
The advantage is obvious: The sender does not have to merge the several people’s feedback into one document.
