Cool concept but really sucks if you’re the only recipient using DeltaChat. Plus it comes with all the privacy drawbacks of email. And I get tons and tons of spam so anything I actually care about is quickly buried.
No, you get spam because the email protocol doesn’t stop spam. You could create a new email address but then you have to give that to everyone who might not appreciate yet another contact method they have to remember for you.
I could be wrong but I’m pretty sure DeltaChat uses PGP, which leaks all of your metadata to your email provider, ISP, and governments. It isnt private but is secure.
These days the best thing you can do is use Signal.
Do note, because it’s using email, the recipient and sender are not private, along with the time, and probably the relative size of the messages.
The specific content of each message should be private as long as the encryption is done well. I haven’t looked at it so I don’t know if it implemnts safeguards to verify who you’re messaging with (besides using the email address) and I don’t know if it uses PFS (Perfect Forward Secrecy) to protect against a key getting compromised.

No spam, because it is a family group for sharing non-public pictures etc.
You’d only get spam if you invited a spammer to chat.
The privacy comes from the E2EE.

I haven’t used Signal.
Is your ‘registered Signal number’ your phone handset number?

[You are right, Delta Chat uses AutoCrypt, which is OpenPGP based.]
