About

Resend is a developer-first email platform that has quickly become the default choice for AI-native companies, SaaS startups, and modern teams who need email that just works. Founded by the team behind React Email, Resend treats email sending as a first-class developer experience: a clean REST API, typed SDKs in every major language, React-based email templates that compose like components, built-in deliverability monitoring, and first-class support for both transactional emails (signup confirmations, password resets, receipts) and marketing broadcasts (newsletters, product updates, audience campaigns) — without forcing teams onto two separate tools. Under the hood, Resend handles the operational complexity that kills most email projects: domain verification with DKIM, SPF, and DMARC set up in minutes; dedicated IPs with automatic warm-up; bounce and complaint handling; inbox-level deliverability analytics; and a webhooks event stream that makes it easy to react to opens, clicks, bounces, and deliveries in real time. The free tier includes 3,000 emails per month with full API access, making it accessible to side projects and early-stage startups; Pro and higher tiers add larger volumes, dedicated IPs, priority support, and advanced analytics. For any team building an AI product that needs to send notifications, magic links, digests, or campaigns, Resend removes the email infrastructure problem in an afternoon.
