I found 2 post talking about this where the answer was using Gravatar to set an image on the mail account. I tried but it’s not working. On WordPress is showing fine, I’ve the pfp, bur if I send a mail it’ll not show the pfp.
Idk if something changed, if it takes some time to update or if we have to do something else.
If someone knows how this works it’ll be very helpfull ^^
