Resend
Marketing · resend.com
Overview
Resend is an email platform built for developers, offering a REST API, SMTP relay and official SDKs for sending transactional and marketing email, with React Email for building templates as React components. Alongside the API it ships Broadcasts, a no-code campaign editor with Audiences, Contacts, Segments and Topics, plus event-triggered Automations for lifecycle sequences. It came out of Y Combinator's W23 batch and raised an $18M Series A in December 2024.
The problem Resend solves
Teams sending both product email and marketing email usually run two systems — an API for password resets and receipts, and a separate campaign tool for newsletters and drips — which splits sending reputation, duplicates contact data and forces marketers to file tickets with engineering for every template change. Resend puts both on one sending domain: engineers get a REST API, SMTP relay and React-based templates, while marketers get Broadcasts, a no-code editor over the same Audiences, Segments and Topics. It fits best at SaaS startups where a small marketing team and a small engineering team share one email pipeline.

How to evaluate Resend
A listing helps create a shortlist; a trial with the team’s real workflow decides whether the tool fits. Use this reading with the structured facts and confirm changes with the vendor.
Workflow fit
The record describes it as a fit for Developers and product teams sending transactional/marketing email or building AI agents that send email. Check that this context matches the volume, roles, and processes your team needs it to support.
Pilot questions
- Can Resend complete the critical workflow without manual work outside the product?
- Do the recorded connections (React Email, Cursor, Claude (MCP), Node.js) support the sync direction, permissions, and volume we need?
- What user, usage, storage, support, or security limits appear after the headline starting price?
Evidence and freshness
