How to contact Glyphs for support discount

Hi guys, we are here crazy about having the new version of Glyphs 3.
We bought the version 2 (at feb 20th 2020) and we were wandering if we can get a discount as the website say ([removed plaintext e-mail for spam protection --mekkablue]). We wrote to that email but unfortunately we could not send it cuz it doesnt work.
Is there any possibility you help us on this?

Thanks for your time!

Hola guys,

Please check your mailbox - I just sent you a discount code.

Best regards
Tim
