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?

Best regards
