Is e-mail sending from LN+ down/not working?

I attended swap https://lightningnetwork.plus/swaps/24175 , but I did not receive any e-mail. Not for starting, comments, even though  notifications are activated.
The last mail from LN+ I received was on 16. Feb 2026.
Now I activated Telegram notifications, and this works, but not e-mail.

PS.: I already checked my spam folder.
