Resend is positioning itself as email infrastructure for developers and agents, expanding from transactional sends into marketing automation and shared inboxes. Its growing GTM presence centers on builders assembling their own systems from APIs and developer tools. Practitioner conversation covers transactional email inside custom applications, agents running newsletters, and the practical cost of operating a small company's stack. It also appears alongside database, hosting, and messaging tools in implementation discussions. Recent inbox launch coverage adds receiving and managing email to a conversation previously centered on sending.

Business Profile
Resend grew from an open source email-template project in 2022 into a sending platform launched through Y Combinator in 2023. Its [company history](https://resend.com/about) centers on developer experience and getting messages delivered. The independent business has $21M in recorded funding and a team of about 74, with customers spanning established brands and developer software companies. Its product expansion now covers marketing automation, shared inboxes, and its own sending infrastructure, extending the business beyond its original transactional-email entry point.
Agent Readiness
Measures how easily your agents can build on it — API, MCP, CLI, SDK, docs depth. Methodology →
Resend makes its email platform callable through an API, SDKs, CLI, and a [hosted MCP server](https://resend.com/changelog/remote-mcp-server) with OAuth authentication. Plugins and skills bring those capabilities into coding agents. The October [Inboxes launch](https://resend.com/blog/announcing-inboxes) extends that approach into receiving, organizing, and replying to email, with people and agents sharing conversations through the same underlying platform.
