## What it does

AhaSend exposes tools for sending messages, diagnosing failed delivery, and checking deliverability. An agent can also work with domains, templates, contacts, lists, campaigns, webhooks, routes, suppressions, SMTP credentials, and sub-accounts.

The server calls the AhaSend v2 API, while the API key scopes control which tools are available. List operations return pages of 20 items and allow up to 100; the returned cursor fetches the next page. You can use an HTTP MCP endpoint or build the Go module with a stdio transport.

Campaign sends require a person’s confirmation. A one-off send above `MaxRecipientsPerSend`, whose default is 50 recipients, is refused, so bulk email goes through a campaign instead.
