How to work with push/email/SMS for retention?

To improve retention through push notifications, email, and SMS, it is important to use personalization and audience segmentation.

• Push notifications are effective for quick engagement, such as reminders about unfinished actions or special offers. It is important not to overuse them to avoid irritating users.

• Email is suitable for more detailed communication: sending useful content, news, promotions. It works well with trigger-based emails (e.g., welcome, reactivation).

• SMS generally has a high open rate and is suitable for urgent and important messages, such as order confirmations or discount notifications.

Key points:

1. Segment users based on behavior and preferences.
2. Use A/B testing to optimize messages.
3. Automate communication chains (funnels).
4. Analyze metrics (opens, clicks, unsubscribes) and adjust the strategy.

Example: for users who haven't logged into the app for 7 days, send a push with a personalized offer, and after 3 days — an email with details of the promotion.
