Email List Hygiene Best Practices
Why Clean Your Email List Regularly?
- Improved deliverability: ISPs and email providers monitor bounce rates and engagement to determine if you're a legitimate sender
- Better campaign metrics: A clean list provides more accurate open, click, and conversion rates
- Reduced costs: Many ESPs charge based on subscriber count, so removing invalid emails saves money
- Enhanced sender reputation: Clean lists lead to fewer bounces and spam complaints, improving your reputation
Types of Problematic Emails
| Issue Type | Description | Recommendation |
|---|---|---|
| Invalid format | Missing @ symbol, invalid characters, incorrect domain structure | Remove from list immediately |
| Hard bounces | Non-existent email addresses or domains | Remove from list immediately |
| Soft bounces | Temporary delivery issues (full inbox, server down) | Remove after multiple consecutive soft bounces |
| Role-based emails | Addresses like info@, sales@, support@, hello@ | Segment into separate list or remove |
| Inactive subscribers | No opens or clicks in 6+ months | Run a re-engagement campaign before removing |
| Duplicate emails | Same email appears multiple times | Remove duplicates, keeping only one instance |
Ongoing List Maintenance Tips
- Implement double opt-in: Requires subscribers to confirm their email, reducing invalid addresses
- Use an email validation service: Verify emails at the point of collection
- Clean your list quarterly: Regular maintenance prevents deliverability issues
- Run re-engagement campaigns: Attempt to re-engage inactive subscribers before removing them
- Monitor engagement metrics: Track open and click rates to identify potential issues
