The Hidden Cost of Poor Deliverability
Most eCommerce brands focus obsessively on email open rates, click rates, and revenue per email — but ignore the silent tax being levied on every campaign: spam folder placement. Industry data shows 10–15% of permission-based emails never reach the inbox. For a brand sending 100,000 emails a month, that's 10,000–15,000 messages disappearing before a single recipient ever sees them.
Unlike a dropped conversion rate, spam folder placement is invisible. You don't know it's happening until you're deep in a deliverability crisis. The calculator above estimates the revenue impact using your own metrics — use it as the business case for investing in email deliverability infrastructure.
How the calculation works
- • Emails lost = monthly sends × spam rate %
- • Opens lost = emails lost × your open rate
- • Conversions lost = opens lost × your conversion rate
- • Revenue lost = conversions lost × average order value
