Block Gmail addresses

Problem

Gmail isn't delivering our emails to some newsletter subscribers.

Solution

When someone enters a @gmail.com or @googlemail.com or @google.com email address, open up a popup window that says the following:

Sorry Gmail users!

Google isn't delivering our newsletter to all subscribers. They aren't even sending it to junk, just black holing it.

For that reason we can't accept any Gmail addresses. We recommend one of these alternatives:

• https://tuta.com/
• https://www.startmail.com/
• https://proton.me/mail
• https://www.fastmail.com/
