Hey everyone!
So I kept forgetting to follow up with clients and it was driving me nuts. Tried a bunch of reminder apps but honestly couldn't be bothered to actually use them.
Then I had this dumb/brilliant idea - what if I could just BCC myself with a time delay? Like when I'm emailing someone, just add mailto:myself[+3d@gmail.com](mailto:+3d@gmail.com) to BCC and get the email back in 3 days?
Turns out Gmail (and most email providers) have this "plus addressing" thing where anything after the + still goes to your inbox. So I built a little service that:
- Watches your inbox for these special addresses
- Sends you back your original email at the right time
- Works with stuff like +2h (2 hours), +7d (7 days), +1w (1 week)
- Also works with other services than Gmail, I personally use it on my own custom mail server
Been using it for months and it's honestly been a game changer. No more "oh shit I forgot to follow up" moments.
Just made some huge updates and open-sourced it in case anyone else has the same problem. It runs on your own server so your emails stay private. Also added a bunch of languages because why not.

Not trying to make this a big thing, just thought someone might find it useful!
