Formula: plan base + max(0, emails − 10,000) × overage per 1k + optional dedicated IP. Free $0: 100 emails/mo, no overage. Basic $15 / Pro $16.50 / Platform $18 — each includes 10,000 emails; overage $1.80 / $1.30 / $1.20 per 1,000. Dedicated IP from $50/mo on Pro or Platform, typically gated at 300,000+ emails/mo. “Auto” picks the cheapest paid plan including overage. Examples: Basic 10k → $15; Basic 30k → $15 + 20 × $1.80 = $51; Pro 30k → $16.50 + 20 × $1.30 = $42.50.

Estimates only. Official list prices as of 2026-11-04 (Asia/Shanghai); the provider's pricing page prevails. Sources: Postmark pricing
