Forwarding one message (or conversation) at a time is all nice and good.

How about forwarding disjointed threads, though? What about those cases — email support, for instance — when you need to forward an entire message including all its headers and source code?

In a tad roundabout but still not entirely unreasonable manner, Gmail lets you do all this by saving emails as files and then sending them as attachments.

How to Attach Emails in Gmail to Forward or Resend Them

To attach an email in Gmail you must first save each message you want to forward as an EML file in Gmail:

  1. Open the message.
  2. Click the More button () next to Reply near the email's top.
  3. Select Show original from the menu that has appeared.
  4. Now save the file linked from Download Original.
    1. Note: Make sure the saved file ends in .eml. Rename it if necessary.
    2. Tip: If you want to remove other recipients' email addresses from the messages you forward, open the .eml file in a text editor and edit it as needed.

Once you've saved the message as an EML file, then you can attach it to a Gmail message:

  1. Start a new message in Gmail.
    1. Tip: You can start your forward by selecting Forward for one of the messages, of course; in this case, delete the text beneath and including ---------- Forwarded message ----------.
  2. Type the message you want to send, then click the paperclip (Attach files) icon.
  3. Navigate to and select the desired .eml file you saved before.
    1. Tip: If you are sending more than one file, hold down the Ctrl key and select all the files you want to attach.
  4. Edit the message's subject and body.
    1. If you did not start by forwarding a message, you can use "Fwd: " followed by one or more of the original message subjects. To copy these subjects, open a new Gmail window or tab, or click Save Now in the composition window and find it again later in the Drafts label.
  5. When you've finished editing your email click Send.

Can I Forward Multiple Emails in Gmail?

Yes, you can forward multiple emails in Gmail. As mentioned in Step 3 above you can as easily attach and forward multiple messages by holding the Ctrl key on your keyboard while you select the messages you want to attach. However, keep in mind that both Gmail and your recipient's email services may have limitation on how large attachment files can be. If you're concerned that the files might be too large, you can always zip the files before you email them.
