How it's calculated
Bounce rate = bounced ÷ sent × 100. Smartlead's auto-protection divides by total leads instead, which understates the rate early in a campaign. Why that matters.
What's a good bounce rate?
Under 2% is healthy. 2-5% is a warning. Above 5% is where platforms pause campaigns. How many bounces burn a domain.
Too high? Verify the leads you haven't sent to yet before you resume.
