The challenge

The agency ran campaigns for many clients with very different list quality. One bad list could bounce, harm a client's domain reputation, and put the agency's results and retainer at risk. Cleaning each list by hand did not scale.

The solution

The agency verified every client list with the bulk verifier before sending, managed from one account with credits that never expire. Each job's valid, risky and invalid breakdown became part of the client report.

Frequently asked questions

Can one account serve many clients?
Yes. Verify unlimited client lists from a single account, and because pay-as-you-go credits never expire, unused credits carry across clients and months.
