Outreach list hygiene and suppression best practices

What list hygiene means in practice

• Remove obvious bad addresses before import.
• Normalize field formatting for cleaner personalization.
• Keep list segments small and context-specific.
• Avoid recycled, stale, or purchased contact dumps.

Suppression rules you should always apply

• Suppress contacts after explicit unsubscribe requests.
• Suppress hard bounces immediately.
• Suppress replied contacts from future sequence sends.
• Optionally suppress low-intent leads after repeated no-response attempts.

Why this improves reply quality

Clean lists create better matching between message and recipient. That means fewer irrelevant touches and a higher share of meaningful replies.

Weekly maintenance loop

1. Review bounce and reply status.
2. Update suppression list.
3. Refine targeting criteria for next batch.
4. Trim underperforming sequences.
