About this Add-on
Example: If you plan to invite someone to your Birthday-Party you can add the day after your Party as the expiration date of your Email. On the day after your Party the expired mails are not deleted but moved out of the inbox of your party-guests.
Another use case of this addon: If you receive an Email from an sender without this addon you can simply change the expiration date of this mail to a date of your own interest.
