Frequently asked questions
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.

Use the MCP client adapter to create a connection. LlamaIndex discovers all tools and wraps them as query engine tools compatible with any LlamaIndex agent.
