Agreed, I don’t even have a problem with the “ProtonMail” PGP version label, as it is unobtrusive, but the extra comment link feels like an ad forced into every one of my emails, despite the fact I am a paying customer.

This should not be forced on paying customers

Never had a complaint about this before. Thanks for bringing this up. We will check into this.

Whenever I send an email with PGP via ProtonMail, a comment containing https://protonmail.com is added to the PGP message. This can add an annoying rich preview of the ProtonMail website on the recipient's end. Just as paid users can remove the "Sent with ProtonMail" email signature, I would appreciate it if we could also remove the ProtonMail link from our PGP emails.
