Yandex.Mail makes it easy to work with different message categories and sorts them into system folders.
Subscriptions and social networks
Emails sorted to Mailing lists and Social networks are stored only in these folders and duplicate copies aren't saved anywhere else.
After that, all newsletters and social media notifications will be sent back to the Inbox and other folders.
Emails with attachments are stored in their relevant folders, but are also displayed under the With attachments category to make them easier to find.
