# Automated Email Verification Before Outbound

> Ask your agent to gate outbound data on an explicit email acceptance policy.

[Agent guide: CLI and SDK instructions →](/docs/guides/automated-email-verification)

## 1. Have your context ready

Have known email addresses, source IDs, your freshness rule, and a policy for catch-all and unknown outcomes.

## 2. Ask your agent

Paste this into your agent, then provide your task and example inputs when it asks:

```deepline-prompt theme={null}
/deepline-gtm Prepare an email-verification gate for this list using Deepline. Define accepted, rejected, held, and provider-error outcomes before running a pilot. Keep identity and suppression checks separate from mailbox status. Preserve each address, source record, verification evidence, and available time information. Include ambiguous and previously verified records in the pilot. Do not send email or activate a campaign.
```

Complete any requested sign-in yourself. Give the agent the missing information before approving execution. Provider-backed work can incur usage.

## 3. Review the result

A positive verifier result passes only the checks it actually proves. Catch-all, stale, identity-conflicted, or suppressed records remain held under your stated policy.

Ask your agent:

```deepline-prompt theme={null}
/deepline-gtm Compare the result with the acceptance rule we agreed. Show the evidence for accepted and rejected outcomes, unresolved questions, and recorded Deepline usage where work ran. If work is still running or a response is uncertain, inspect the original saved execution before proposing another request. Explain the next decision I need to make.
```

Approve a larger job, recurring work, or external changes only after reviewing that decision.

## Check your understanding

Does a positive mailbox response override a known suppression match?

> **Show the answer**

> No. Mailbox evidence does not establish campaign eligibility. Apply
> suppression and identity policies independently.
