Verification results

NeverBounce returns clear verification statuses:

Result	Description	Action

invalid	Email does not exist or bounces	Remove from list
disposable	Temporary/throwaway email address	Avoid emailing

Best practices

• Verify emails at point of capture for best data quality
• Re-verify periodically (recommended every 3-6 months)
• Treat “catchall” emails as valid but monitor for bounces
• Remove “disposable” emails - they indicate low-quality leads
• Use suggested corrections to fix typos automatically
• Cache results to avoid redundant verification

Integration benefits

• Improved deliverability: Only email verified addresses
• Better sender reputation: Reduce bounce rates
• Cost savings: Don’t pay to email invalid addresses
• Higher engagement: Focus on real contacts
