Unfortunately, once you've sent a letter on Slowly, it cannot be edited or deleted.
The design was made to be like a real-life experience of sending a physical mail, where once it's sent, you can't take it back. Additionally, recipients are promptly notified upon your letter being sent, so the sender cannot retract the letter.
However, we understand that unforeseen circumstances may arise. To address this concern, you can enable a reminder to pop up before you send a letter, allowing you to double-check and confirm your message before it's sent.
To enable it, please follow these steps:
- Go to in the bottom menu
- Go to located at the top right corner
- Scroll down to the Friends section
- Turn on Confirm before sending the letter
