How to Reduce Email Bounce Rate
High bounce rates hurt your sender reputation and can get you blocked. OutSends provides tools to validate emails, remove invalid addresses, and monitor bounce patterns to keep your list healthy.
What you'll need
Before you start, make sure you have the following ready.
- An OutSends account
- A contact list with at least 100 addresses
- Recent campaign data showing current bounce rate
Step-by-step guide
Follow these steps to complete the setup.
Validate emails before sending
Use OutSends email validation to check addresses before your campaign goes out. Invalid emails are flagged and removed.
Enable automatic bounce handling
OutSends automatically categorizes bounces (hard vs. soft) and suppresses hard bounces from future sends.
Set up bounce alerts
Configure notifications for when bounce rate exceeds your threshold (e.g., 3%). Investigate immediately.
Clean your list quarterly
Remove contacts that have bounced multiple times. OutSends offers bulk list cleaning tools.
Segment by engagement
Create segments of active vs. inactive contacts. Reduce sends to unengaged contacts to lower overall bounce risk.
Tips for best results
Pro tips to get the most out of this setup.
- Hard bounces (invalid address) → suppress permanently
- Soft bounces (inbox full) → retry 3 times, then suppress
- A bounce rate above 5% will trigger ISP blocks — clean before you send
Frequently asked questions
What is a good bounce rate?
Below 2% is excellent. 2-5% needs attention. Above 5% is critical — stop sending and clean your list.
Can I recover soft bounces?
Yes, soft bounces are temporary. OutSends retries automatically. If the address works later, it can be unsuppressed.
Does email validation guarantee zero bounces?
No, validation checks syntax and domain existence but cannot guarantee a working inbox. It typically catches 80-90% of problem addresses.
