PGP Confirmation e-mail not send

Hi,
I am not receiving the verification email on my PGP validation. It shows up "as key pending validation" on Launchpad. I have also checked the mail spam/unknown mail folders.

I can see that the key is registered with the Ubuntu keyserver using the receive-keys command.

damian:~$ gpg --keyserver keyserver.ubuntu.com --recv-keys 9F43BD60
gpg: Schlüssel E854D11C9F43BD60: "Damian Tometzki (Erstellt am 17042017) <email address hidden>" nicht geändert
gpg: Anzahl insgesamt bearbeiteter Schlüssel: 1
gpg: unverändert: 1

Can you please check on this to let me know if there is some issue and when I can receive the confimation email.
PGP key: DA6801BBC5A0E9442284D74EE854D11C9F43BD60 | Id: 9F43BD60
email: <email address hidden>
Name: Damian Tometzki

Best regards
