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 15 distinct TLDs its top three are .com (75.3%), .org (16.5%), .ca (3.6%) — together 95.3% of the 558 domains, which makes the footprint narrow — three TLDs cover most of it, which is typical of a regional or single-market operator. The service most often observed on the same domains is Microsoft 365 (Mailbox, 283 domains, 50.7% of them), followed by Mimecast (18.3%). 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.
