Hi jonny cat
Try using proton https://account.proton.me/mail
or gmx
gmx link was wrong. I'll get the right one. Here we go
https://www.gmx.com/mail/create-email-address/
here marti again https://dice.marti.triplea-game.org/
It's the only one triplea uses. There's been talk of upgrading it.
Edit
Hang in there. We'll get it sorted 🙂
