For AI builders
Give your agent a way to send.
Your app or agent sends through the same API as everything else. Add our MCP server to put a person in front of every send.
3,000 free emails every month. The MCP server is in private preview and not yet published to npm or a public directory.

- From
- hello@updates.example.com
- To
- maya@example.com
- Subject
- Welcome to Example
- Message
- Hi Maya, thanks for signing up. Your workspace is ready whenever you are.
Sending requires a client that supports approval prompts.
How it works
From prompt to inbox, with you in the loop.
- 01
Connect your workspace
Verify a sending domain and create an API key with only the scopes your agent needs.
- 02
Review before sending
The MCP server shows the full email in your client and waits for you to approve it.
- 03
Follow the outcome
Read the status and events for each email. Accepted for processing is not the same as delivered.
MCP tools
Three tools. No surprises.
The server runs on your machine with your own scoped key and talks only to the Sendaro API.
- Every send needs your approval for the exact message.
- An approval works once and expires after ten minutes.
- Your API key stays in local config, never in a tool call.
- Retries reuse an idempotency key, so nothing sends twice.
sendaro_send_emailAsks you to approve the complete message, then sends it.
sendaro_get_emailReads one email and its delivery events.
sendaro_list_emailsLists recent emails in the workspace.
The API is ready when you are.
