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 132 distinct TLDs its top three are .com (57.4%), .org (4.7%), .de (4.7%) — together 66.8% of the 1,853 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.
