Looking at the source of the email it seems broken for text/plain and text/html :disappointed::
Docker tag *docker.io/amir20/dozzle:latest* ( https://github.com/amir20/doz=

I guess this is an issue with hermes in: https://github.com/crazy-max/diun/blob/21f5d0839a630a2f2b75e64e41aa3f3d7b37198e/internal/notif/mail/client.go#L73
We might need to do something like the telegram notif to escape some markdown syntax: https://github.com/crazy-max/diun/blob/387ee68e7220d12573aac7f7c9b4911f8c9a2167/internal/notif/telegram/client.go#L65-L72
Will take a look, thanks for your report!
