However, if you’re a Gmail user, you might be interested to learn that Google has announced that in a new feature part of Gmail, users will now be able to send emails as an attachment in another email. Essentially, you would be sending like a document file but it will contain the email as part of it.
According to Google, “We’ve heard from you that there are situations where attaching emails makes more sense than forwarding separate emails, like wanting to forward multiple messages related to a single topic. With this new functionality, you can do exactly that. Sending emails as attachments allows you to write a summary email message to your recipients, and attach the set of supporting emails that recipients can directly open in their mail client.”
The feature will be rolled out to users and no action is required on their end. If you have the feature already you should see the option to “Forward as attachment” in your emails.
