In «Messages» section you can study detailed statistics on each type of emails. For instance, statistics on emails about users registration can be studied separate from statistics on password recovery emails.
To start using this option you need to add a special header: X-Mailru-Msgtype or X-Postmaster-Msgtype to each email. X-Mailru-Msgtype header shows statistics on Mail.ru users and X-Postmaster-Msgtype header is used for statistics on emails sent both to Mail.ru and My.com.
As index you can use a random sequence of English letters and figures up to a maximum of 32 symbols. The header index will be used for grouping emails of the same type.
Statistics on types of emails is updated once a day.
