Send old emails as attachments to a new email. This is the novelty introduced by Google on its Gmail mail service, which offers an alternative to forwarding and downloading. The new feature, arriving on the desktop version of Gmail, allows you to attach one or more received emails to a new email.
The option is called "forward as attachment", and to use it just drag the old emails into the new message. This way you avoid having to download the emails you want to forward.
As Google explains in a post, the function is designed to send multiple emails, a situation in which the forwarding of individual emails is inconvenient and dispersive. One of the cases of use is, for example, in the workplace, when a new person joins a team or is employed on a project already started, and must be made aware of previous information and exchanges.
