Competitor prices from their public pricing pages, checked 7 October 2026. Monthly prices in USD, excluding taxes. Totals with extra emails use each provider’s published overage rate. Each price is the cheapest way to send that many emails a month on the provider’s published plans. Postmark has no 250,000 tier, so its price is for the Basic plan with 300,000 emails.
