I have a long chain of 20+ emails in Gmail I wish to forward to someone else. I don't want to forward them individually.
How can I do that?
In the latest GMail, you can do this via the "More" menu, if you have the conversation selected:
More, then click
Forward All. This results in a new email sent to whomever you choose with all the emails in the conversation / thread in a single email that looks like this:
(all the emails in the conversation / thread will be included in the body here as one giant email)
And this forward itself ends up being part of the original conversation, so I don't know what happens if you forward a conversation twice. :)
In the current version of GMail, as of 7/22/13, hitting the Forward button does "Forward All" by default.
Just for the record, Forward All is no longer in the hamburger menu; it's now (2017) the small right-pointing black arrow on the right side of the subject line, above the first email in the thread.
