Meta PM: deciding which email notifications to send, to whom and how often
Company: Meta
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
You are a product manager at Meta and you own the email notifications its apps send to users. How would you optimize them? Decide what "better" should mean for these emails, then explain what you would change and how you would measure the result.
```hint A click is not the goal
An email that gets clicked is not always an email worth sending. Think about what each email should do for the person receiving it and for Meta, and what it costs when it misses.
```
### Clarifying Questions
- Which app's emails are in scope: Facebook, Instagram, or every Meta app?
- Which kinds of email: activity notifications (comments, tags, friend requests), digests, account and security messages, or re-engagement emails to people who stopped visiting?
- What prompted the work: falling engagement with the emails, rising unsubscribes or spam complaints, or a push to bring back lapsed users?
- Are push and in-app notifications part of the same system, so that choosing the channel is a lever, or is email planned on its own?
### What a Strong Answer Covers
- A goal for email that reflects long-term value to users rather than short-term clicks, with a primary metric and guardrails.
- Segmentation of recipients and of email types, with a reasoned choice of where to focus.
- Concrete, prioritized levers on what is sent, to whom, how often, when and through which channel.
- An experimentation plan that measures the incremental effect of email, including over the long term.
- Risks such as notification fatigue, damage to sender reputation with mailbox providers, and consent rules for email.
### Follow-up Questions
- A test that doubles email volume lifts daily active users this week. Do you ship it, and what else would you look at first?
- How would you decide whether a particular notification should go by email, by push, or only appear inside the app?
- Spam complaints rise and mailbox providers start filtering Meta's emails into junk folders, including password-reset emails. What do you do?
Overview: A Meta product manager question on improving the email notifications its apps send to users. It tests setting a goal beyond clicks, segmenting recipients and email types, choosing concrete levers for volume, relevance, timing and channel, and designing experiments with guardrails for long-term effects.
