Resend is a smaller, developer-first ESP with a modern API, React templates via react.email, and a cleaner deliverability setup flow. SendGrid and Mailgun are older, deeper platforms with more legacy features (advanced routing, XML-era APIs, mature IP management) but also more complexity. Most modern startups pick Resend for greenfield projects because the DX is faster; teams sending tens of millions of messages per month may still prefer SendGrid or Mailgun for the volume tiers and dedicated IP management. Postmark is the closest 'developer-first' peer but focuses only on transactional email.
Yes — Resend maintains react.email, a companion library that lets you write email templates as React components with Tailwind-style styling. Rendering happens on the server, so the template outputs the HTML the SDK sends. This means email templates live in the same monorepo as the rest of your React/Next.js app, share a design system, and get type-checked with the rest of the codebase — a real advantage over hand-maintained HTML tables.
Yes. Broadcasts is Resend's marketing-email product: audience manager, campaign editor, per-recipient tracking, and basic A/B testing in the same product as the transactional API. It's enough for product announcements, newsletters, and simple lifecycle campaigns. It is not as deep as Mailchimp or Klaviyo for advanced segmentation and multi-step drip journeys, so specialist marketing teams may still keep a dedicated ESP alongside.
Free tier: 3,000 emails/month and 100/day with one domain. Pro at $30/month covers 50,000 emails and multiple domains. Scale plans start around $90/month with higher volume and priority support. Enterprise adds SSO, custom SLAs, dedicated IPs, and a security review; pricing is quote-based. For very high volume senders (multi-million per month) it's worth comparing against SendGrid and Postmark since incremental email costs vary.
Official SDKs cover Node, Python, Go, Ruby, PHP, Java, and .NET. First-class integrations exist for Next.js, Cloudflare Workers, Supabase, and Convex, so common full-stack combinations (Next.js on Vercel with Supabase or Convex) work out of the box with generated types and edge-runtime support.
Compare features, test the interface, and see if it fits your workflow.
