Change Email address does not work

I don't receive Email at t-online.de so I can't verify the new address

I don't know what kind of spam protection you have. Isn't it possible that the email is in a spam folder? In case of a strong anti-spam, it may happen that the email won't arrive. I have seen that you have made several requests over a short period of time, so maybe the system evaluated it as a spam?

Alternatively, send us an email at [email protected] and let us know which email address you would like to change it to.
