Does Secret Letter send an email later?
No. The unique link is created immediately. Save it or share it yourself; the message becomes readable on the reveal date.
Can I write anonymously?

Is the letter private?
The letter is not listed publicly, but anyone with its unique link may be able to access it. Treat the URL as a secret and do not include high-risk information.
Does the recipient need an account?
No. The recipient opens the letter in a web browser using the link.
