Directory category: Saas. The classification comes from include: mechanisms in the SPF record. It describes observed DNS infrastructure, not a commercial relationship and not the placement of any individual message.
Across 86 distinct TLDs its top three are .com (61.9%), .in (4.7%), .de (2.9%) — together 69.6% of the 720 domains, which makes the footprint moderately concentrated, with a recognisable home market.

Its share of SPF-publishing domains has not moved measurably in 30 days. Directly comparable by the same detection rule: Shopify, Pardot (Salesforce), CodeTwo Email Signatures 365. Ranking between them reflects what is published in DNS, not delivery quality or volume sent. All figures come from a single daily DNS snapshot (2026-07-26); a domain appears here when its published records match the include: mechanisms in the SPF record rule, which is an infrastructure fact, not a commercial relationship.
