According to Live Direct Marketing's daily Tranco top-1M scan (July 13, 2026), Robin is the SaaS sender for 162 domains — 0.03% of 617,702 SPF-publishing domains. Detection method: include: mechanisms in the SPF record.
Robin is a SaaS platform that sends email on behalf of customer domains. It is identified in internet-wide surveys via its presence in SPF include mechanisms, appearing across a distributed set of smaller organisations rather than consolidating traffic at a few large brands.
Robin's deployment footprint—concentrated in the .nl region and frequently paired with Microsoft 365—reflects the way many smaller organisations build their email infrastructure: layering specialist senders atop a primary email provider to handle transactional, campaign, or compliance-governed sends. For mail administrators and deliverability teams, this pattern underscores the importance of correctly maintaining SPF, DKIM, and DMARC when multiple senders are used, as misconfiguration at this layer is a common source of authentication failure and delivery delays.

Robin's presence in SPF records alongside other senders illustrates a core infrastructure challenge for smaller organisations: when a domain uses both a primary email service and one or more specialist senders, the SPF record must include all of them without exceeding DNS query limits, and each vendor's DKIM records must be correctly configured and reachable. Robin deployments that share a domain with Microsoft 365 must ensure both vendors' DKIM keys are published and that SPF include chains are kept within DNS operational limits; failures here cascade to authentication checks and can degrade inbox placement.

Robin is a SaaS email delivery platform; it is not a separate filtering or reputation system to test against. If your organisation uses Robin or receives mail from domains using Robin, ensure that SPF and DKIM records for both Robin and any other senders on that domain are correctly configured to avoid authentication failures.
162 domains in the Tranco top-1M use Robin as their SaaS sender as of July 13, 2026 (0.03% of SPF-publishing domains), according to Live Direct Marketing's daily DNS scan.
Robin accounts for 0.03% of SPF-publishing domains in the top 1M. Whether you should seed a test mailbox there depends on how much of your audience it represents — the co-usage table above shows the services it appears alongside most.
Robin's largest TLD is .nl (49.4% of its domains); it appears across 17 TLDs in total.
