Deliverability Checklist

Use this when sending at scale, warming a list, diagnosing spam placement, or cleaning inactive subscribers.

1. Authenticate the sending domain.
2. Send only to consented subscribers.
3. Suppress hard bounces and long-term inactive contacts.
4. Monitor spam complaints and unsubscribes.
5. Avoid sudden volume spikes from a cold list.
6. Review content, links, and sender identity before launch.

Tips:
- Deliverability is a system habit, not a one-time fix.
- Poor list quality usually hurts more than individual spam words.
