A high bounce rate is one of the fastest ways to damage your email sender reputation. ISPs like Gmail and Outlook track your bounce rate closely, and exceeding 2% can land you in spam folders—or worse, get you blacklisted entirely.
What's a Good Bounce Rate?
Hard Bounces vs Soft Bounces
Understanding the difference is crucial:
- Hard bounce:Permanent failure. The email address doesn't exist or is invalid. Remove immediately.
- Soft bounce:Temporary issue. Mailbox full, server down, or message too large. Retry a few times, then remove.
6 Strategies to Reduce Bounce Rate
1. Verify emails before adding to your list
Validate format at signup, then verify the collected list before a campaign.
2. Clean your list regularly
Run bulk verification quarterly at minimum. Monthly is better for high-volume senders.
3. Remove hard bounces immediately
Never send to an email that has hard bounced. One and done.
4. Watch for engagement signals
Inactive subscribers often become invalid. Consider sunsetting after 6 months of no engagement.
5. Use double opt-in
Confirm new subscribers with a verification email. Reduces fake and typo emails.
6. Monitor your bounce rate weekly
Set up alerts when bounce rate exceeds 2%. Act fast to protect reputation.
A Practical Step: Email Verification
Verifying your email list before sending can reduce avoidable bounces. Bulk email verification helps you review current address and mailbox signals before a campaign.
With Peopledat, you can:
- Upload your entire list for verification
- Find addresses that fail current syntax, domain, or mailbox checks
- Flag risky addresses like catch-alls and role emails
- Export labeled results for your own sending policy
💡 Pro Tip
Verify your list at least 24 hours before your campaign. Emails can become invalid quickly—especially for B2B lists where employees change jobs frequently.
Prevention is Better Than Cure
While cleaning existing lists is important, checking an address at collection can catch obvious failures earlier. Use Peopledat's dashboard list-verification workflow, versioned single-verification API, or origin-bound advisory widget according to where the address enters your system.
