Cost Scale Analysis: When to choose Resend over Stytch
Both Resend and Stytch rely on identical hybrid flat-step pricing curves in this simulator. At equivalent workloads (free tier up to 10,000 MAUs, followed by a flat $25/mo up to 50,000 MAUs), their price trajectories align exactly, meaning the commercial decision pivots strictly on technical fit and compliance footprint.
Notably, Stytch supports a broader compliance footprint (HIPAA, BAA) compared to Resend (None), representing a critical differentiator for security audits.
