About Resend

## Intro Resend is an email API built for developers. You use it to send the emails your app needs, such as welcome messages, password resets and receipts, and it also supports marketing broadcasts to a contact list. It has become a favorite with startups and AI app builders because setup is quick, the documentation is clear and the dashboard is easy to read. If your app needs to send email and you do not want to wrestle with an older provider, Resend is usually the first name builders mention. ## Key features - **React Email templates.** Build emails with React components instead of hand-coding old table layouts. Resend maintains react-email, an open source component library for this, with examples like welcome, password reset and weekly digest emails. - **SDKs and SMTP.** Official SDKs cover Node.js, Python, Ruby, PHP, Go, Rust, Java, Elixir and .NET, plus a REST API and SMTP. There are integrations for frameworks like Next.js, Remix, Nuxt and Astro. A test mode lets you simulate deliveries, opens, clicks, bounces and complaints without sending real email, so you can test your app's email logic safely before launch. - **Broadcasts, audiences and automations.** An editor for writing and sending marketing emails, contact management with custom attributes, and analytics on how people engage with each broadcast. Paid plans include 10,000 automation runs, then charge $0.0015 per run, which is handy for simple triggered sequences without another tool. - **Deliverability tools.** DKIM, SPF and DMARC setup, blocklist monitoring, a suppression list for unsubscribes, regional sending and optional dedicated IPs, plus webhooks for delivery, open, click and bounce events. ## Best for Resend is best for founders building apps in code, or with AI coding tools, who need reliable transactional email without fighting a complicated dashboard. It also works well for simple product updates and newsletters sent to your users. Non-technical marketers who want visual automations, landing pages and forms will be happier with a dedicated platform like MailerLite or Brevo. It is a particularly good match if you build with Next.js or an AI coding assistant, since sending your first email takes only a few lines of code. ## Pricing summary The free plan includes 3,000 emails per month with a 100 per day limit and up to 3 domains. Pro is $20 per month for 50,000 emails, and Scale is $90 per month for 100,000 emails. Extra emails on paid plans cost $0.90 per 1,000. Pro and Scale remove the daily sending limit. Dedicated IPs are a $30 per month add-on for higher-volume senders. ## Quick verdict Resend is the easiest modern email API to start with, and the free plan covers most early-stage apps. Its marketing features are still lighter than dedicated email marketing platforms, so treat it as your app's email engine first and a newsletter tool second. If you are starting a new app today, it is hard to find a simpler email setup.
