Resend

Resend is a modern email API built specifically for developers and SaaS founders. It handles both transactional emails (order confirmations, password resets) and marketing campaigns through a unified platform with transparent, usage-based pricing. The free tier gives you 3,000 transactional emails/month and unlimited marketing emails to 1,000 contacts—perfect for early-stage products.\n\nWhat developers love: clean REST API, React Email component library integration, dedicated IPs available, and pricing that scales with actual usage. At $20/month for 50,000 transactional emails plus unlimited marketing emails, it's competitive. The API-first design means you can send emails directly from your Node.js, Python, or JavaScript backend without complex SMTP configuration. Perfect for SaaS founders who want email infrastructure that thinks like a developer.
