Warmy.io

API and webhooks

Warmy has an API, with documentation on its site, and the vendor says it supports automation through platforms such as n8n. Check the API reference for the individual endpoints you need.

An idea: when a new sending domain is created in your stack, add it to Warmy through the API and hold campaigns until placement looks healthy.

Native integrations

Warmy says it works with any email service provider and lists many on its site, including HubSpot, Mailchimp and Brevo. It also integrates with Google Postmaster.

An idea: connect Google Postmaster so domain reputation sits in the same view as warm-up progress, and check it before every large send.

MCP server

The vendor's own blog says it has no MCP server today, so an AI assistant cannot call Warmy directly yet. The API is the route to automation for now.
