It may be confusing to read, but it's actually very simple: A new Gmail feature lets you attach an email or an entire conversation to another email.
In a recent post, Google explains that, in some cases, the new feature may prove more practical than sending separate emails.

"Sending emails as attachments allows you to write a brief description to your recipients and attach the entire email message that recipients can open directly in their email client," the publication says.
Sure, it's not a frequent need, but it doesn't hurt to have it as an option.
To enable it, you can start a new email message and then simply drag the subject line from a list of emails and the software will recognize it as a potential attachment.

Email attachments will be converted to .eml files and there is no limit to how many emails you can attach.
This feature is being offered to users starting December 9th and will take up to 15 days to become available to all users.
To check if the feature has already reached you, open a Gmail message and click on the three-dot menu – you should see the “Forward as attachment”.
