Email list cleaning for agencies.
Client lists arrive in every state imaginable. A standard cleaning workflow protects your results and your client's sender reputation.
No monthly subscription · Credits never expire · Unknown results use no credits
Why agencies need a standard process
When a campaign underperforms, a dirty list is often the cause. Verifying at intake sets expectations early and gives you a clear record of what you started with.
A repeatable workflow
- Intake: collect the client's list as CSV
- Verify: run a bulk job in MailGuard
- Report: share the Passed/Failed/Unknown breakdown with the client
- Agree: decide together what to do with Unknown results
- Launch: send only to the approved export
Why pay as you go suits agencies
Client work is project-based. Credits that never expire mean you can buy once and use them across clients over months, without a monthly plan sitting idle.
What MailGuard can help with
- Checking single addresses or bulk CSV/TXT lists before a campaign
- Sorting each address into Passed, Failed, or Unknown, with a plain-language reason
- Flagging disposable domains, role accounts, syntax issues, and catch-all behavior
- Exporting a filtered list that contains only the results you choose
- Paying only for Passed and Failed results, since Unknown results use no credits
Limitations
Verification reduces uncertainty before sending. It does not guarantee inbox placement and does not replace consent or list hygiene.
Verification doesn't confirm that a client's list was collected with consent. Ask about the source.
Frequently asked questions
Can I bill clients for verification?
Many agencies include it as a line item. MailGuard shows credit usage per job, which makes it easy to account for.
