About
Resend is an email platform for developers that helps teams send transactional and marketing email at scale. It provides a modern API-first workflow with SDKs, SMTP, REST access, and React Email support so developers can integrate email delivery directly into their applications.
The platform includes tools for sending, receiving, tracking, and managing email programs, along with deliverability features such as domain authentication, suppression handling, webhooks, and regional sending. It is designed to give engineering teams a streamlined experience for building, testing, and operating email infrastructure.

Free Tier Value
The pricing page shows a Free plan at $0/mo with capped recurring limits: 3,000 emails/month and 100/day, plus 10,000 automation runs and 5 AI credits/month. The cheapest paid plan is Pro at $20/mo for 50,000 emails/month, so the free-tier value is conservatively $0 because this is a capped free tier and the prompt’s rule says to value it by the lowest paid plan that exceeds the cap, prorated only when computing a recurring equivalent; here the free plan itself is already priced at $0 and no separate credit/trial applies. Feature parity is about 50% because core sending/API features are included, but higher-tier benefits like more domains, higher AI credits, and no daily limit are gated.
