Connect Superagent's managed AI assistants to MultiMail for sending, reading, and managing email — with human oversight for production-deployed agents.
Superagent is a platform for building and deploying AI assistants with tool use, memory, and RAG capabilities. MultiMail provides the email infrastructure layer that gives Superagent assistants the ability to send, receive, and manage email on behalf of users in production environments.
When agents run in production without direct developer supervision, email oversight becomes critical. MultiMail's default gated_send mode ensures every email drafted by a Superagent assistant requires human approval before delivery, providing the safety layer that production-deployed agents need.
Connect Superagent to MultiMail by configuring MultiMail API endpoints as custom tools in your Superagent assistant. The REST API approach works with Superagent's tool registration system, giving your assistant structured email capabilities.
Superagent assistants run in production without direct supervision. MultiMail's oversight modes provide the email safety layer that production agents need — from human approval for every send to fully autonomous operation.
Superagent supports custom tools that call external APIs. Register MultiMail's send_email, check_inbox, and reply_email as tools in your assistant for structured email capabilities.
Start with gated_send (assistant composes, human approves) and progress to autonomous as your Superagent assistant proves reliable. MultiMail's five oversight modes let you scale agent autonomy safely.
Superagent's built-in observability shows you how your assistant uses tools. Combined with MultiMail's audit logs, you get full visibility into every email action your agent takes.
Superagent supports multiple LLM providers. Your MultiMail email tools work the same regardless of which model powers your assistant, so you can switch providers without changing the email integration.
No code, no dashboard. Paste this to your AI agent — it connects MultiMail, creates an inbox, and builds the flow for you.
Sign up at multimail.dev, create a mailbox, and generate an API key from your dashboard. Your key will start with mm_live_.
Sign up for Superagent and obtain your API key. You can use the hosted platform or self-host the open-source version.
Create custom tools in Superagent that map to MultiMail's API endpoints — send_email, check_inbox, reply_email, and others.
Create a Superagent assistant with a system prompt that explains email oversight modes. Attach the MultiMail tools to the assistant.
If your mailbox uses gated_send mode (the default), review and approve pending emails in the MultiMail dashboard before they are delivered.
