About Resend
Overview
Resend is an email delivery platform built specifically for developers. It handles both transactional and marketing emails, giving teams a single API and SDK to send messages that land in inboxes instead of spam folders.
Companies of all sizes use Resend to deliver important emails. The platform offers SDKs for Node.js, Python, Ruby, Go, Rust, Java, PHP, Elixir, .NET, and frameworks like Next.js, Remix, Nuxt, Express, Hono, Redwood, Bun, and Astro.
Key Benefits
- Start sending emails in minutes with SDKs for 14 programming languages and frameworks.
- Test mode simulates email events without risking delivery to real recipients during development.
- Modular webhooks send real-time notifications for deliveries, opens, bounces, and link clicks directly to your server.
- Built-in contact management lets you import lists of any size and track individual contact attributes.
- Broadcast analytics provide insights into how audiences interact with marketing email campaigns.
- React Email integration enables creating email templates without writing table-based HTML layouts.
How It Works
You sign up, grab an API key, and call the Resend SDK from your codebase — a single send() method with from, to, subject, and html parameters returns a JSON response with the email ID. For marketing campaigns, you use the visual editor or React Email to design templates, then send broadcasts through the dashboard with built-in analytics and contact management.
Use Cases
- Backend engineers integrating transactional emails like password resets, order confirmations, and welcome sequences into web applications.
- DevOps teams setting up automated notification pipelines with webhook-driven alerting for system events.
- SaaS founders sending product onboarding sequences and account-related transactional communications at scale.
- Marketing teams at developer-first companies sending broadcast newsletters and campaigns with contact segmentation and deliverability tracking.
- API-first product teams that need SMTP relay alongside RESTful API access for hybrid email workflows.
Why Choose This Product
Resend is best suited for engineering teams who want an email API that feels like a modern developer tool — clear SDKs, React component support, real-time webhooks, and a test mode for safe iteration. The free tier handles up to 3,000 emails per month, making it accessible for small projects, while the Pro, Scale, and Enterprise tiers serve growing and high-volume senders. Standard plans retain data for 30 days; longer retention requires an Enterprise plan.
