New-user source: SEO (Non-brand search). Similarweb 2026-09: direct 34.1%, organic search 49.4%, referrals 9.9%; 96% of keyword traffic is organic, and many of the terms are long-tail terms tied to email/account logins like 'gmx', 'noreply', 'que significa el status full en verificacion de correo', and 'twitter video downloader'; the blog is updated almost daily (Gmail/GMX/WEB.DE login, temp mail comparisons, ZoomInfo, etc.), which is clearly programmatic SEO. Referrals are only scattered sites such as techbullion and medium, and the only social channel is Reddit; the founder filled in no channels on TrustMRR. Note that TrustMRR's revenue data stops at 2026-04-06 (the Stripe key expired), so the current MRR is unknown.
