How we compiled this
Official pricing pages were re-fetched on 2026-06-18: litmus.com/pricing (shows only Enterprise contact-sales; no self-serve prices published), mailgun.com/pricing/inspect, emailonacid.com/pricing, mailtrap.io/pricing (Email Sandbox section), mailosaur.com/pricing, testi.at/pricing (JavaScript-rendered, not machine-readable), and mailpit.axllent.org plus github.com/axllent/mailpit. Litmus self-serve pricing is no longer displayed on the official pricing page; the $500/mo Core figure is corroborated by Capterra and multiple third-party trackers (xhtmlteam, emailexpert, machinecdn) reporting the Aug 2025 Validity overhaul. Litmus annual discount is reported only vaguely (10-20%) and not published as an exact figure, so it is set null. Mailosaur prices shown are the published annual-billing rates ($20/$50 per month billed annually); the monthly-billing rate is not published, so the draft's $25/$62.50 'monthly' figures were removed as unverifiable inflation. Mailtrap SOC 2 Type 2 is explicitly stated on the pricing/compliance pages. Testi@ prices ($7/2-day, $14/31-day, $50/6-month) are corroborated by saasworthy/spotsaas/G2; the supported-client count is reported as ~50 (not 130+) by those sources, so the inflated count was corrected. accessedAt 2026-06-18.
Last verified 2026-06-18. We re-check published prices and compliance on a recurring cadence and update this page when they change.
