According to Live Direct Marketing's daily Tranco top-1M scan (July 13, 2026), UKG / UltiPro is the SaaS sender for 543 domains — 0.09% of 617,702 SPF-publishing domains. Detection method: include: mechanisms in the SPF record.
UltiPro is a cloud-based human capital management platform operated by UKG (Ultimate Software Group) that includes email capabilities for transactional and internal communications. When organisations send email through UltiPro, they authenticate those messages via SPF records that reference UltiPro's mail infrastructure.
UltiPro's presence in SPF records across the web is concentrated in the long tail of smaller organisations and mid-market businesses, particularly within the .com domain space. Its frequent co-appearance with Microsoft 365 SPF entries indicates a typical customer profile: businesses that have adopted Microsoft cloud services and then integrated UltiPro for HR workflows and employee communications. For email senders and deliverability engineers, this footprint pattern means UltiPro is a niche infrastructure provider, but proper SPF configuration remains essential for organisations using it.

Organisations that run both Microsoft 365 and UltiPro in their email stack must ensure their SPF record authorises mail from both infrastructures without exceeding DNS lookup limits. Misconfiguration — such as redundant include mechanisms or excessive SPF entries — can cause SPF failures that harm deliverability. Senders and IT administrators should audit their SPF records to confirm UltiPro's mail servers are explicitly listed without duplication, particularly when Microsoft 365 entries are also present.
