Problems to add a new email in my Atlassian Account

[SolluSaaS]

Good morning, I am trying to add the email address trello.sollusaas@loginseguro.online to my Atlassian account, and when I try to do this, I receive an error that says:

"Invalid email - The provided email address is not allowed. Use another one."

The email is valid and can send and receive emails.

I would like to know why it does not work.
