Can I send an email with HTML content and track whether it was delivered?

Absolutely. Use the `send_email` tool with your HTML body, then use `get_email` with the returned ID to check delivery status, open events, and bounce details in real time.

How do I check if my sending domain DNS records are correctly configured?

Run `list_domains` to find your domain ID, then use `get_domain` to inspect the full DNS record set (SPF, DKIM, return path). If records are pending, trigger `verify_domain` to re-check.

Can I add subscribers to an audience for broadcast campaigns?

Yes. First use `list_audiences` to get the target audience ID, then call `create_contact` with the subscriber's email and optional name fields. The contact is immediately available for broadcast targeting.
