What is a push notification?

A push notification is a short message that an app sends to a user's phone, tablet or browser, appearing on the lock screen or in the notification tray even when the app is not open. Streaming services use them to bring viewers back to watch.

How push notifications work

The viewer grants permission, and the device registers a token with Apple's or Google's notification service. To send a message, the streaming service passes it with the token to that notification service, which delivers it. Tapping the notification can open the app directly at a title.

What streaming services send

  • A new episode of a series the viewer is following
  • A live event about to start
  • A reminder to continue something half watched
  • New arrivals in a genre the viewer watches
  • A rental about to expire, or a title leaving the catalog
  • A payment problem, or a trial about to end

Doing it well

Relevance decides everything. A message about a series the viewer is watching is welcome; the same announcement sent to everyone is noise, and noise leads people to switch notifications off, after which you cannot reach them at all.

Ask for permission at a moment when its value is obvious, such as when the viewer adds a series to their list. Limit how many messages one person gets per week, respect time zones, and measure opens, plays that follow and opt-outs.

Planning a streaming service?
Do push notifications work on smart TVs?

Not in the same way. Television platforms offer home-screen recommendations and continue-watching rows instead. Push is mainly a mobile and web channel.

How many notifications are too many?

There is no fixed number. Watch the opt-out rate: if it rises after a campaign, the message was not relevant enough to the people who received it.

What is the difference between push and in-app messages?

Push reaches viewers outside the app. In-app messages appear only while the app is open, and need no permission.
