Users around the world who infrequently log in to Facebook say it has been increasing re-engagement prompts via emails and text messages recently

Context & Ripple Effects
The re-engagement blitz lands against a backdrop of slow erosion in Facebook's own data: Pew found 70% of users logging in daily back in 2015, but the marginal user has been drifting — teens on the platform slipped to 88% from 94%, and GlobalWebIndex showed active posting falling from 50% to 34% of users in a year as lurking replaced sharing.
What changed is the channel: after years of tuning in-app hooks — the Notifications update and what Brad Frost called increasingly overt, aggressive notification design — Facebook is now spending its off-platform inventory, email and SMS, on the users who stopped showing up.
First-order effects
- Infrequent users get more emails and text messages pulling them back, meaning Facebook's retention machine now reaches past the app into personal communication channels it doesn't fully control.
- The move targets exactly the cohorts already flagged as soft — lapsed posters and the teens whose share of the platform has been shrinking since 2014.
Second-order effects
- Escalating prompts raise the fatigue-and-backlash risk Brad Frost documented for in-app notifications: each additional email or text makes opt-outs and muted threads more likely, so the tactic can burn the very address book it mines.
- Rivals competing for the same lapsed attention now face a bar set by whatever cadence Facebook finds tolerable, pushing re-engagement spend toward SMS and email across the sector.
Third-order effects
- If organic usage keeps flattening while daily-login numbers hold, growth shifts structurally from product features to purchased attention — paid re-engagement becoming a standing line item rather than a campaign tool.
- Heavy use of email and text as retention levers invites the same scrutiny that followed in-app notification design, since the messages arrive in channels users treat as personal rather than promotional.
The trend: As organic engagement plateaus, social platforms are shifting growth from in-product hooks to off-platform re-engagement through email and SMS aimed at their most lapsed users.
