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