Worked example: 30k emails → SES à la carte ≈ $3.12, Resend Pro $20, Mailgun Auto → Foundation $35, Postmark Basic $51 / Pro $42.50 / Platform $42. Mailgun is now listed; SendGrid and Brevo are still skipped because their official pages were not cleanly re-readable. Deep-dive: Mailgun calculator · Postmark calculator.
