Email Debt Forgiveness Day is the day when you are allowed to respond with no shame or embarrassment to old emails that have been sitting in your inbox for weeks or months or even years. You don’t have to apologize. You don’t have to agonize over what the receiver will think. Respond and you are forgiven.
The idea came from one of my favorites podcasts, Reply All. Here is their page explaining the idea. The actual day declared by Reply All is April 30th but if you are shomer shabbas don’t hesitate to take advantage of the idea tomorrow or Sunday.
Include the link of explanation and you are good to go!
