Every time I create a free Tuta account, it gets automatically deleted after just one day, and I'm not sure why!

I want to clarify that I'm not creating multiple accounts intentionally; I only create a new one because the previous one was deleted.

In the past, I received a message saying, 'You can't send or receive emails for 2 days' after creating an account. However, with these recent accounts, I haven't received that message at all.

Does anyone have a solution for this issue?
