Enter your list size, bounce rate, and campaign details. See the exact revenue impact of email bounce — and your ROI from cleaning your list.
Average order value, lead value, or LTV — whichever applies to your campaigns.
Mailchimp ≈ $1.50/1K, Klaviyo ≈ $2/1K, SendGrid ≈ $0.80/1K, ActiveCampaign ≈ $1.20/1K.
Assumptions: BounceZero verification priced at $5/1K (100K tier). Revenue impact assumes 90% bounce reduction. Inbox placement uplift of 15% applied to net deliverable volume. Results are estimates — your actual ROI may vary.
The calculator shows three distinct sources of return — each real and measurable.
Every invalid address you remove means one fewer paid send per campaign. On a 50K list with 10% invalid rate and $1.50/1K ESP cost, that's $75 saved per campaign — $1,800/year at bi-weekly frequency. Pure cost reduction.
Bouncing emails can't convert. If 10% of your list is invalid and your conversion rate is 2%, you're missing 200 conversions per 10,000 addresses reached. At $50 AOV that's $10,000 in annual hidden revenue loss.
High bounce rates damage your sender score — meaning even valid addresses receive your email in spam instead of inbox. Reducing bounces improves inbox placement for your entire list, amplifying the revenue impact beyond just the invalid addresses removed.
