According to Live Direct Marketing's daily Tranco top-1M scan (July 13, 2026), Hornetsecurity (AntispamEurope) is the mailbox provider for 207 domains — 0.03% of 658,711 domains with MX records. Detection method: primary MX record (lowest preference).
Hornetsecurity, also known as AntispamEurope, is a German-based email hosting and filtering service that provides mailbox services and anti-spam protection, primarily for organisations throughout Central Europe. It operates independently from the larger global email providers and serves a substantial base of smaller to medium-sized businesses and domains.
For email practitioners, Hornetsecurity's presence in the long tail of European email infrastructure — particularly concentrated in the German .de domain space — signals that regional and geographic variations in email policy matter. Senders targeting European recipients should account for its filtering rules as a distinct layer in their deliverability testing; receiving organisations using Hornetsecurity need to understand how its policies shape inbound mail handling and filtering behaviour.

Hornetsecurity's strong footprint in Germany and the German-speaking region, combined with its long-tail positioning away from dominant global brands, means that email campaigns and infrastructure built solely around North American or United Kingdom ISP standards will encounter gaps in Central European markets. Deliverability practitioners should treat Hornetsecurity as a distinct test case when recipients include German organisations, as its filtering rules, authentication expectations, and sender-reputation thresholds often differ from larger international providers.
