Resend

The best way to reach humans instead of spam folders. Deliver transactional and marketing emails at scale.

Resend is for developers, founders, startups, SaaS companies, and product teams that need reliable email infrastructure inside their apps. It is especially useful for teams building web apps, B2B SaaS products, developer tools, marketplaces, AI products, or platforms that need to send transactional email, product notifications, lifecycle messages, newsletters, or marketing broadcasts. The ideal user is a technical builder or engineering team that wants a clean API, strong documentation, modern templates, visibility into email events, and better deliverability without managing a complicated email stack.

Resend helps developers send transactional and marketing emails without dealing with clunky email tooling, poor developer experience, or deliverability problems. Products need to send important emails like signups, password resets, onboarding messages, notifications, receipts, broadcasts, and lifecycle emails. Resend gives teams a modern email platform with APIs, SDKs, SMTP support, webhooks, React email templates, analytics, contact management, domain authentication, and deliverability tools so important emails are more likely to reach inboxes instead of spam folders.

Resend is listed in Developer Tools. Pricing is listed as Free.
