... it's possible to embed images in the signature...
From what I read in this topic I got that it's not...
As @Paris Geek mentioned, - it is possible to insert an image in the signature.
I suspect the problem here is that @Maci69 cannot find how to insert the image into the signature.
While I am opposed using images in signatures, I also thought for long time that it was impossible in Aquamail. It is hard to notice that one can scroll that panel at the top, and there are a few more items on the right. (At least in the dark theme, non-material design).
@Maci69: To add the image to the signature, long-press on the account in the account list, -> options and folders -> Composing and sending -> Signature . There, press on "Switch to rich text" (if you had a plain text signature). A set of icons will be at the top of that "inset/popup" window. Touch and hold with your finger on it and move the finger to the left. The last icon in that row, after the "cross" item, allows you to insert an image.
I hope this helps.
Please, kindly let us know if this was what you were looking for.
