The issue you’re describing is why I’m not keen on email, and why I mention Signal as an alternative I’ve considered - Signal is a user-friendly way of ensuring both encryption and that meta-data isn’t accessible to providers on either end unless someone’s device is compromised.
The reason I’m interested in encryption is that I want a higher baseline of security for these orgs. In a changing political landscape it is hard to say what may become sensitive over time. Hypothetically, if one of these orgs is distributing contraceptives internationally we want neither meta-data about who is contacting them nor message contents to be accessible to providers. Since encryption is a pain with email we can assume both are accessible to providers when using that. Ideally I want encryption to be an easy default for both the orgs and the people contacting them.
Thank you for this - yes, I understand that this is a tall order, but I also can’t help but think that most of these requirements are fairly common individually?
As for address stability, it would be good to have a point of contact that’s easy to put on a website or flyers or whatever.
Thinking aloud here, I guess one option could be to have a signal account and a setup similar to what is described under the ‘Start Your Own Announcements-Only Service on Signal’ heading here: https://crimethinc.com/2024/05/27/the-sunbird-how-to-start-an-announcements-only-thread-on-signal-and-how-organizers-in-austin-used-one-to-coordinate-solidarity-with-palestine to be able to check the incoming messages from multiple devices. I guess some level of tech-savviness would be needed for the setup of multiple Signal accounts on a single machine if people are using their own hardware, but otoh it also means minimal setup for people contacting the organization. If more than five (max number of linked signal devices) people are responding to messages, group chats with the incoming user, the org account and the account of the person responding could be setup for searchability etc. This solves some problems but creates others…
