Hello,
just came back from meeting where we discus Structured Email. In short this could be used like current function “Set handling for tagged mail: In subfolder, In subject, Do nothing”.
For example if you receive e-mail from e-shop that is containing specific JSON-LD or HTML microdata server can make some action like add tag to mail or more,..
Similar thing should be already implement in Gmail like action button or highlights.
Think this could be nice new feature in MailCow. Did I miss it in MC? Would you like it? Is it hard/easy for developers to implement this?
