WiseStamp — cloud email-signature management with a server-side stamping and relay service.
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 16 distinct TLDs its top three are .com (71.3%), .org (10.9%), .io (5.0%) — together 87.1% of the 101 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 Google Workspace (Mailbox, 44 domains, 43.6% of them), followed by Microsoft 365 (36.6%). 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 (2026-07-25); 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.
