Can I check if my domain's DNS records are correctly configured?

Yes. Use the `get_domain` tool by providing your verified domain name. Your agent will retrieve the status of SPF, DKIM, and MX records, helping you identify if any DNS dependencies are missing or misconfigured.

How do I see which emails have recently bounced from my domain?

The `list_bounces` tool allows your agent to extract the suppression logs for a specific domain. You'll see the email addresses that failed to deliver, providing insights into audience health or sending boundaries.

Can my agent validate an email address before I send a message?

Absolutely. Use the `validate_email` tool to check if an address is valid, deliverable, and doesn't belong to a disposable service. This is perfect for ensuring high-quality data before triggering outbound sends.
