Resend wins on developer experience — cleaner API, better documentation, React email template support, and a modern dashboard.

For high-volume production email with advanced deliverability needs, SendGrid is safer.
Yes, SendGrid offers 100 emails/day on the free plan with no expiration. This includes API access, basic analytics, and the event webhook. For development and small-scale production, this is sufficient. No credit card required for signup.
