Resend
Email & MarketingModern transactional email API built by former Vercel engineers with React Email templates, excellent DX, and reliable deliverability.
Resend is a modern email API platform built by former Vercel engineers for developers who need reliable transactional and marketing email delivery, with clean APIs, SDKs for Node.js, Ruby, Python, PHP, and Go, and seamless React Email integration for building templates as React components. The platform includes REST API and SMTP relay support, batch sending, scheduling, open/link tracking, webhooks, and deliverability optimization with DKIM/SPF/DMARC authentication, backed by SOC 2 Type II certification. It offers a generous free tier of 3,000 emails/month and a Pro plan at $20/month for 50,000 emails, though as a newer platform it may feel limited compared to established providers for high-volume enterprise senders.
