Delta.chat link in emails triggers spam filters

[link2xt]

I’d rather have default signature empty:

Catchy signature for convincing people to have a look at Delta Chat?

Next version of Delta Chat will display last received signature in the contact profile, so “Sent with my Delta Chat Messenger” does not fit there well: The idea is to let users put their contact information, homepage and so on in the profile. I would actually like the default signature to be empty. Current signature reminds me of the “Sent from my iPhone” dark pattern.
