Best Practices for Bulk Validation
- Validate email lists before sending campaigns to reduce bounce rates
- Remove invalid emails immediately to protect sender reputation
- Flag disposable emails for manual review or exclusion
- Be cautious with role accounts - they often have lower engagement
- Re-validate old lists (6+ months) before re-engagement campaigns
- Keep validation results for future reference and auditing
- Segment lists based on validation results for targeted campaigns
Why Clean Your Email List?
Lower Bounce Rates
Invalid emails bounce, which hurts your sender reputation. Keep your bounce rate under 2% by removing bad addresses.
Better Deliverability
Email providers trust senders with clean lists. Better deliverability means more emails reach the inbox instead of spam.
Cost Savings
Why pay to send emails to invalid addresses? Save money by only sending to real, active mailboxes.
Accurate Analytics
Clean lists mean accurate open rates, click rates, and engagement metrics for better decision making.
Protect Your Domain
High bounce rates can get your domain blacklisted. Bulk validation protects your sending reputation.
Compliance
Many email marketing platforms require clean lists. Stay compliant with industry best practices.
