How is it different? In my experience it’s easier as they’ve already heard of email.

You need a phone number to sign up which requires identification in most countries.

Also anyone who knows your username can ping where you are at any time: https://gist.github.com/hackermondev/45a3cdfa52246f1d1201c1e8cdef6117

The protocol doesn’t really matter when you send encrypted messages over it like Delta Chat. Signal is not private nor decentralized and SimpleX doesn’t have encrypted group chats last time I tried

I asked specifically for relevant issues and you just link general issues with smtp that have no impact on Delta Chat?

SMTP is not secure

Delta Chat sends encrypted messages over it so that’s irrelevant.

SMTP is not efficiency

Your phone can run LLMs, it can send a couple packets. Also this “chattyness” can be seen as an advantage as it is extremely robust and works on any network however inconsistent.

SMTP doesn’t have a way to ensure stuff is delivered

Yeah duh? It’s decentralized. You can’t ensure that the recipient doesn’t take down their server?…

Etc. I feel like I’m wasting my time replying to all these because it seems you didn’t even take the time to read them yourself.

Could you be more concrete? In what relevant way do you think it does not work as an instant messenger? Keep in mind that Delta Chat is not a theoretical thing and it works as well as any other messenger.

Because delta chat is using an open protocol (email) and you can run your own servers meaning it is decentralized unlike Signal. Also it is actually anonymous unlike Signal, so you don’t need to give anyone your phone number and people can’t find where you live just by knowing your username.
