The challenge
Northwind's buyer and seller lists had been growing in the CRM for years, and nobody had cleaned them. A 14% bounce rate was dragging down deliverability — even hand-written agent emails were landing in spam.
The marketing lead was spending roughly two days every month manually scrubbing exports before each newsletter, and still missing dead addresses.
What they did
- 1Exported the full contact database and ran it through BounceBlock in one upload — email verification and phone validation together.
- 2Removed hard-invalid addresses, flagged catch-all domains for a separate low-volume segment, and de-duplicated contacts that had been entered twice with different formatting.
- 3Set a recurring 90-day re-verification so the list never drifts back to a high bounce rate.
“We didn't realize how much deliverability we were losing until the bounce rate dropped and our open rates jumped the same week.”
Illustrative scenario with representative numbers.
