# Email Bounce Handling for Product Teams

Classify bounces, suppress unsafe recipients, and keep critical product email observable.

Bounce handling protects sending reputation and reduces wasted delivery attempts. Treat permanent failures differently from temporary failures, and make recipient state visible to support and operations.

## What this means in practice

- Hard-bounce suppression
- Temporary-failure retry rules
- Provider event ingestion
- Recipient-level history and auditability

## Implementation checklist

1. Ingest provider delivery and bounce events.
2. Classify permanent versus temporary failures.
3. Suppress destinations that permanently fail.
4. Retry only transient conditions with bounded backoff.
5. Expose recipient status to support workflows.

## Questions teams ask

**What is a hard bounce?**

A permanent delivery failure, often because an address does not exist or the domain cannot receive mail.

**Should temporary bounces be suppressed?**

Not immediately. Retry transient issues carefully, then suppress only after a policy threshold is reached.
