Mailgun

Sim's Mailgun integration adds 8 Mailgun tools to the AI agents you build in Sim's visual workflow builder — no code required. Send emails and manage mailing lists with Mailgun. Teams often pair Mailgun with Rippling and Linear in the same agent.

You can send Message, get Message, list Messages, create Mailing List, and get Mailing List with Mailgun in Sim, plus 3 more Mailgun tools listed on this page. Each runs as a tool inside an AI agent block, so an agent can chain Mailgun with services like Rippling and Linear and apply LLM reasoning between steps.

Connecting Mailgun takes about five minutes: (1) Create a free account at sim.ai. (2) Create an agent in your workspace. (3) Drag a Mailgun block onto the workflow builder. (4) Paste your Mailgun API key to authenticate — you can find it in your Mailgun account settings. (5) Pick a tool such as "Send Message", wire up its inputs, and click Run — your agent is live.

Add a Mailgun block to your agent and select "Send Message" as the tool. Send an email using Mailgun API. Fill in the required fields — inputs can reference outputs from earlier steps, such as text generated by an AI block or data fetched from another integration. No code is required.
