Can I check the open rate for a specific email using the agent?

Yes! Use the `get_email_analytics` tool with the Email ID. Your agent will fetch the detailed statistics, including deliveries, opens, and clicks, directly from Buttondown.

How do I add a new subscriber with a specific tag?

Simply ask the agent to `create_subscriber` and provide the email address and a JSON array of tags, for example: `["customer", "api-lead"]`. The subscriber will be added to Buttondown instantly.

Does the integration allow creating a new draft email?

Yes. Use the `create_email` action and set the status to `draft`. You can provide the subject and the body in markdown format, and it will appear in your Buttondown account ready for review.
