Editorial Policy

Review criteria

• Feature scope — what the tool covers (testing, warmup, DMARC, monitoring)
• Provider coverage — which mailbox providers are tested
• Pricing transparency — whether pricing is published and clear
• Free tier — what you get without paying
• User consensus — aggregated reviews on G2, Capterra, Trustpilot

What we do NOT test

We do not run independent accuracy benchmarks, stress-test support SLAs, or personally verify enterprise-tier features. Our reviews are based on public data. Every commercial page includes an evidence block stating exactly what was and was not checked.

Updates

We review content regularly and update pages when features, pricing or market conditions change. Each page shows a "Last reviewed" date.
