The Gmail mail service has "dynamic" messages that allow you to fill out questionnaires or reply to letters without opening a new page. At the same time, such actions can also be performed on third-party pages, only the user must remain authorized in the mail and not exit it.
It is reported that you can reply to a comment in Google Docs through a notification that "fell" in the mail. Thus, instead of individual letters, users will see actual message threads. It's kind of like forums or comment threads.
However, some companies, like Booking.com, Nexxt, Pinterest, and so on, have already begun testing the new feature for their newsletters. This approach allows you to save a picture on a Pinterest board or view recommended hotels and rental options in OYO Rooms without leaving your email.
At first, this feature will be only in the web version of mail, but later similar functionality will appear in mobile applications. Also, Outlook, Yahoo! mail services will work with this format. and Mail.Ru. True, administrators will have to choose the beta version for now.
The basis of this innovation is Accelerated Mobile Pages (AMP) technology, which Google uses to speed up the loading of sites on mobile devices. For the first time, the corporation showed the version of AMP for Gmail in February 2018. And the technology itself was originally developed for G Suite customers.
