Resend
Developer-first email API with React email templates and simple SDK.
Overview
Resend is a developer-first email API with React email templates and simple SDK. It handles react email, api-first, webhooks, and analytics, and it's best suited for developers wanting a modern email api. Launched in 2023, it's a relatively recent entrant that's been gaining traction.
The free plan is free for 3k emails/mo — enough for most people to evaluate whether it fits. It's designed for small teams, striking a balance between simplicity and collaboration features.
Strengths
- Includes React Email as a core feature, purpose-built for email marketing workflows
- Includes API-First as a core feature, purpose-built for email marketing workflows
- Free for 3K emails/mo — generous enough for most small teams to get real work done
- Includes webhooks alongside the core feature set — fewer separate tools needed
Weaknesses
- Free plan exists but key features are locked behind the paid upgrade
- Developer-oriented tooling may not suit non-technical team members
- Deliverability depends on your sender reputation, which takes time to build
- Limited team/admin features if your organization eventually scales up
