I tried to create a filter to forward in Gmail and selected the Also apply filter to 37 matching conversations. However, it did not work and the dialog does warn:

Learn more

Note: old mail will not be forwarded

Clicking Learn more shows in part:

Please note: When you create a filter to forward messages, only new messages will be affected. Any existing messages that the filter applies to will not be forwarded.

Therefore, how can I programmatically cause the 37 emails I'm interested in forwarding to be forwarded without manually sending each one individually in Gmail?

I see this one solution using Google Docs, but it seems pretty complicated to forward my 37 emails, I think manually doing it would be faster than this solution.

There really isn't a simple solution. For 37 messages, I'd almost certainly just do them one at a time. It couldn't possibly take more than a half hour.

One other option might be to use Google Takeout to download all the mail messages with a certain label. The messages will be in MBOX format, and many email clients can import that without issue.


I wrote the Mail Forwarder add-on for Google Sheets that can also help you forward old emails in Gmail to any other email address.

If you control the destination account, you can connect both the new account and the Gmail account to a mail client via IMAP. Then drag the 37 messages from the Gmail account to the new account.


Or use https://github.com/jay0lee/got-your-back , which allows you to transfer emails to/from gmail as a bundle. I'm not affiliated with this group in any way, but found the software to be friendly and very well built.


If you are using Chrome, then I have a simple solution for you which allows you to forward 100 message together everyday.

    Multi Forward for Gmail has a lot of review that says it dies after forwarding 25 emails. And supposedly it has a 100 email a day limit. So buyer beware, it is free. :) Jan 26, 2018 at 4:58
