What Google Workspace represents in this dataset

Directory category: Mailbox. The classification comes from primary MX record (lowest preference). It describes observed DNS infrastructure, not a commercial relationship and not the placement of any individual message.
What the 2026-09-12 snapshot shows about Google Workspace
Across 640 distinct TLDs its top three are .com (52.3%), .org (4.7%), .net (2.9%) — together 60.0% of the 144,136 domains, which makes the footprint moderately concentrated, with a recognisable home market. The service most often observed on the same domains is Amazon SES (ESP, 14,509 domains, 10.1% of them), followed by SendGrid (Twilio) (8.0%). Its share of domains with MX records has not moved measurably in 30 days. Year-over-year the share is -0.43 pp, so the 30-day move is against the longer trend. Directly comparable by the same detection rule: Self-Hosted, Microsoft 365, Unknown / Other. Ranking between them reflects what is published in DNS, not delivery quality or volume sent. All figures come from a single daily DNS snapshot (2026-09-12); a domain appears here when its published records match the primary MX record (lowest preference) rule, which is an infrastructure fact, not a commercial relationship.
