How do I attach an email from a previous conversation or mail to a new message in Gmail?
Forwarding isn't feasible as I need to attach more than one email in a new message to my client.
Is there any way to do this?
This should help.

The correct way to attach an unrelated message is to open it, then open the menu on the right and select "Show Original". It will open a new window with the message in plain text. In your browser, select "Save As" and use the .eml extension. It will create a message that all mail clients (Outlook, Live Mail, Thunderbird...) can open, and it will include all original headers. Then upload that .eml file as an attachment to the message you're sending.
