Proton.me domain
Major problems using proton.me reply-to emails
Very substantially reduced delivery and open rates if using a proton.me domain as a reply-to address when sending Action Network emails.
Action Network have been informed, but no change as yet for this issue.(Aug 2023).
For now it is just best to avoid using this domain.
No issues noticed with the older protonmail.com email addresses.
Note: Local Groups, XRUK or N/R circles, or other people holding roles in the movement can apply for an xxxx@extinctionrebellion.uk email address
