Hi @solomon and @daniel,
I’m Software Architect at TagoIO, I just found the problem on your account, for some reason the DNS records on your end is wrong, our email service is blocked to send email using your domain.
to fix that, you need to fix a wrong record on your dns manager:
The wrong record is:
and it should be:
After you do that, the email service should be work as you expect.
If you are using another service to send email, we can deploy another sub-domain just for TagoIO, if it is your case, tell me.
I’m sorry for that, but if you change your dns records it can stop our service to run correct on your account.
