Gmail’s newest and latest feature will allow you attach emails to other emails without having to download them first. All you need to do is drag and drop one or more emails into the Compose window and you’re good to go. Another way to do this is to select one or more emails from the conversation view, and using the three-dot menu button select “Forward as attachment”.
If you attach an email, the complete conversation view (and stacking) will be preserved, making it much easier to follow by a third party than if you would simply forward every one of its parts, one by one.
Sending emails as attachments lets you write a summary message to your recipients, preparing them for what they’re about to read. The attachments can be opened directly in their mail client of choice, as every attached email becomes a file with the “.eml” extension. You can attach as many emails as you want. When you click on such an attachment, it will open in a new window.
The feature will be rolling out starting today to all units.
