Gitlab.com doesn't send a verification email because it was once mistakenly deleted

I can’t confirm my email.

Email: sergey at asoft.co – WILL BE REDACTED

Once I mistakenly deleted my mailbox for this email address, but shortly after recreated it. Gitlab tried to send me emails in the meantime and they were rejected since the email address was inexistant at that moment. Since then I can’t verify this email for Gitlab.com
