How To Attach An Email To An Email

How to Attach an Email to an Email in Gmail

In Gmail, you can attach messages as .eml files without even downloading them to your device. However, because of the Gmail attachment size limit, any attachments over 25MB will be attached as a Google Drive file.

There are also different ways of attaching emails, depending on if you’re using Gmail via the web or mobile app.
