I tried multiple times to sign up using my email address that uses the domain @sleepy.fish. I was slightly tipped off when firefox attempted to ask if I had made a mistake entering my email... i tried multiple ways to get the verification emails send both via web client and ios app and it simply would not send. To sanity check I created a new account using an old @gmail.com address and immediately got the verification email.

I'm kinda migrating off of mega corp google products though, hence the signing up for firefox sync haha. Would be great if I could figure out how to ensure delivery of the verification email so I can complete account setup with my custom domain email
