I always thought emails were immutable. I need to still believe that’s true.
Also I might be wrong but one major issue I’m having is the lack of deduplication. I sent a video once and then we talked about it for a few hundred emails and all of a sudden I had used up gigabytes of my google cloud storage.
They are, but nothing prevents you from deleting old email and creating a new one with all the same attributes, but without attachments. And that's exactly what happens, according to the quote from the page:
> we can see the message “1 deleted message in this conversation. View message or delete forever.” at the bottom. By default, Unattach puts the original email (the one with attachments) into Gmail’s Bin.
