How does it actually work? Do you save the email content on your servers and generate a link to that content?
No, we haven't worked on this ability, yet - but it is something that we might look into the future. Has huge data privacy implications though
Right now, we simply are able to generate a link to the email that is sharable across everyone that is on the same email thread. It's dependant on some Gmail functions to make it work - what we need to store on our servers is only the email's message ID
