I believe thunderbird has support for Gemini but I haven’t tried that out yet, might be wrong.

That’s a very inspiring idea. Thanks for that!

yea my bad, it looks open source :D

Then maybe I got confused sorry. Somebody mentioned it and then the post was saying it’s a service I thought it wasn’t open. Will check it properly later. Shouldn’t have spoke so quickly I guess

However it does not look like it is open source.
