Verify

Check emails you already have

You have a column with email addresses. This checks if each one is real, catches bounces before you send, and flags catch-all domains.

What you need: A column named /Email in your Clay table

Output columns

StatusDiagnosisCatch-AllMX Provider
Rate limit:2 requests / 1000ms
Timeout:45 seconds
Retries:3, on status 429 and 503

Set these in your HTTP column settings. The prompt includes them, but Clay may not apply them automatically.

Find

Find emails you don't have

You have first name, last name, and company domain. This finds the real email address — verified, not guessed.

What you need: Columns named /First Name, /Last Name, and /Domain in your Clay table

Output columns

Found EmailEmail StatusConfidence
Rate limit:2 requests / 1000ms
Timeout:45 seconds
Retries:3, on status 429 and 503

Set these in your HTTP column settings. The prompt includes them, but Clay may not apply them automatically.

Something not working?

Getting 429 or 503 errors on many rows?

Open your HTTP column settings and set: rate limit to 2 per 1000ms, max retries to 3, and add 429 and 503 to "Status codes to retry". The prompt tells Clay to do this, but it doesn't always pick it up.

Rows timing out?

The default Clay timeout is 1 second — way too low. Set "Response timeout" to 45000 (45 seconds) in your HTTP column settings. Verification with catch-all resolution can take up to 30 seconds.

Still stuck? Email support@filtrat.io with your Clay table URL and which prompt you used.
