What you can do with MailerSend

Each of these is one operation on one endpoint, available both as a workflow step and as a tool an AI agent can call on its own. Nothing bundles several operations into one action, so what a run did stays readable afterwards.

Most endpoints run on the free plan. A few, mainly the ones that publish on your behalf, need a paid plan.

Use MailerSend from Claude Code, Cursor or Codex

Connect MailerSend in LiveContext, create an API key in Settings, then add the LiveContext MCP server to your client. Its MailerSend operations become tools the client can call, next to every other integration you connected.

Claude Code
