When opening an email - especially on mobile - UI elements are too big, to much of them and maybe they shouldn't all be there. See screenshot here - https://drive.proton.me/urls/0G7Y7D3WF0#mL6N900V24rk

1. "This image is from a mailing list" - I know this and usually there is a link for unsubscribe, so not needed there. Also people might feel forced every time they open an email from a list to unsubscribe.

2. "Some images failed to load...." - This is also not necessary. I would rather have a general settings for all emails. Maybe you could find a solution to load images to a temporary place, remove trackers then serve us the clean images.

As you can see in the screenshoot around 80% of the screen is not the content of the email + instead of start reading the email, I have to address options with most of these emails.
