Frequently Asked Questions
Everything you need to know about integrating MailVeri with Clay.com tables.
Does running MailVeri consume Clay credits?
Yes, but only standard HTTP API integration credits (typically 1 HTTP action credit in Clay), which cost a fraction of a cent. This bypasses Clay's native third-party waterfall charges that can consume 10–20 credits per row, resulting in 85%–95% net savings.
How fast is verification when running across thousands of rows?
MailVeri's real-time single verification endpoint responds in real time (typically 500ms–1500ms depending on remote mail server responsiveness). Clay executes HTTP enrichments asynchronously in parallel batches, allowing large tables to populate smoothly.
Can I detect Catch-All and Disposable emails in Clay?
Yes. MailVeri provides granular status classifications including VALID, CATCH_ALL, ROLE_ACCOUNT, DISPOSABLE, and INVALID. You can write Clay formulas to handle each category according to your risk tolerance.
What happens if a mail server times out or yields an UNKNOWN result?
MailVeri never charges you for inconclusive results. Any check that returns UNKNOWN is 100% automatically refunded to your MailVeri credit balance instantly. In Clay, you can configure conditional logic to send only unknown records to a secondary fallback verifier.
