SendWaves email infrastructure API connecting agents and automations to domains, mailboxes, monitoring, and deliverability

Trusted by cold email operators, agencies, and high-volume outbound teams managing hundreds to thousands of inboxes

One API for the entire sending layer

SendWaves is the sending backend
for your agent

Provision domains, spin up mailboxes, authenticate DNS, and monitor health with a few API calls or an MCP tool.

Your agent focuses on the conversation. We handle every piece of infrastructure that makes the send land.

Deliverability health scoring and automated mailbox rotation

Deliverability built into the API

Every mailbox is provisioned with hardened DNS, sending limits, and reputation monitoring. Pull a health score on any inbox and let your agent automatically pause, rotate, or replace before deliverability degrades.

REST API, MCP server, webhooks, and SDKs for LangGraph, n8n, Make, Node, and Python agents

REST API, MCP server, webhooks, and SDKs. Wire SendWaves into your LangGraph, n8n, Make, custom Node, or Python agent in minutes — no console clicking, no manual exports.
