Google Workspace (formerly G Suite) — corporate mail backed by Gmail. Dominant for SMB and mid-market globally.
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.
Across 638 distinct TLDs its top three are .com (52.6%), .org (4.9%), .net (3.0%) — together 60.5% of the 145,836 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, 14,534 domains, 10.0% of them), followed by SendGrid (Twilio) (8.1%). Its share of domains with MX records moved +0.24 pp in 30 days, a change larger than list churn alone explains. Year-over-year the share is -0.21 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 (2026-07-26); 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.
