A proton based newsletter service

I send a newsletter to thousands of subscribers. Due to my subject, many of my subscribers are using Proton or a PGP-compatible service. It is sad that I can’t send an encrypted newsletter.

This could be a paid feature that would allow paid user like myself to send an email to a list of subscribers.

• For each "ProtonGroup", there would be a simple public interface where people could subscribe/unsubscribe
• Optionnally, people could subscribe by sending a mail to a newsletter+subscribe@ adress
• Each ProtonGroup would have a list of emails adresses that are allowed to send email to the whole list.

That’s it. No complex "campaign concept", no tracking. Just an email sent to thousands of subscribers and encrypted if the subscribers are using Proton !
