E-mail blocked by spam filter, didn't receive license

Good evening,

I paid for the SVP Windows license earlier this evening, but I think something went wrong as I wasn't redirected after payment.
I also haven't received any e-mail with a license key or something like that. Could this be resolved?
When I then tried to mail kd@svp-team.com with my normal e-mail address from protonmail.com I kept blocked by the mail server because it thinks it's a spam address.
I also had to register here using an e-mail alias, because I didn't get a password set e-mail. Maybe this is related?
Hope to hear from someone.

Best regards,
