Configure email-capable multi-agent workflows in AutoGen Studio's visual builder — with MultiMail's oversight modes providing safety by default.
AutoGen Studio provides a no-code UI for building and testing multi-agent workflows based on Microsoft's AutoGen framework. By connecting it to MultiMail, you can create email-capable agent teams without writing code — while MultiMail's built-in oversight ensures safety for users who may not understand email automation risks.
The visual builder lets you configure agents, assign skills (tools), and set up group chats. Adding MultiMail email capabilities means defining skills that call the REST API, which your agents can then invoke during conversations. The default gated_send mode queues all outbound emails for human approval.
This combination is particularly powerful for teams that want email automation but lack the engineering resources to build custom integrations from scratch.
AutoGen Studio makes multi-agent systems accessible to non-developers who may not understand email safety risks. MultiMail's gated_send mode provides guardrails automatically — no technical configuration required.
Define MultiMail API calls as skills in AutoGen Studio's UI. Agents can invoke send_email, check_inbox, and reply_email without writing custom code — just configure the HTTP endpoints and authentication.
AutoGen Studio's group chat feature lets multiple agents discuss before sending email. One agent drafts, another reviews, and a third sends — all coordinated visually with MultiMail handling the actual delivery.
Create reusable email workflow templates in AutoGen Studio's gallery. Teams can deploy pre-built email agent configurations that include MultiMail integration and appropriate oversight settings.

}Configure an agent in AutoGen Studio with email skills and appropriate system message.
Sign up at multimail.dev, create a mailbox, and generate an API key from your dashboard. Your key will start with mm_live_.
Install AutoGen Studio and launch the web interface.
pip install autogenstudio && autogenstudio uiIn the AutoGen Studio UI, go to the Skills panel and paste the send_email, check_inbox, and reply_to_email skill functions. Update the API key with your MultiMail key.
Create a new agent in the Agents panel with the email skills attached. Set the system message to explain the oversight mode and email guidelines.
Run a test workflow in AutoGen Studio. Check the MultiMail dashboard for any pending emails generated by the agent and approve or reject them.
