10 Million push notifications for #chatmail messages were delivered in the last 30 days, up from 3 Million half a year ago.

F-droid installs do not use push notifications, and classic e-mail users also do not use push notifications. These usages are therefore not contained in the number which therefore marks a lower bound on number of messages delivered.
