What the app does
Product update emails and transactional email for small SaaS teams. An agent can sign up, connect over MCP, add a sending domain, import opted-in contacts, build a signup form and draft emails on its own. Free to set up and test; sending to subscribers needs a paid plan picked by a human. Billed by emails sent, never by list size.
