According to Live Direct Marketing's daily Tranco top-1M scan (July 13, 2026), UNAS is the SaaS sender for 184 domains — 0.03% of 617,702 SPF-publishing domains. Detection method: include: mechanisms in the SPF record.
UNAS is a Hungarian-based SaaS platform that sends email on behalf of client domains, integrating with senders' infrastructure via SPF include mechanisms. The platform operates in the email infrastructure layer, handling delivery logistics for organisations that delegate outbound mail to a managed service.
UNAS's footprint concentrates in the long tail—smaller websites rather than the largest international brands—and clusters heavily in the .hu (Hungary) namespace. It frequently appears alongside Self-Hosted sending infrastructure, suggesting it is popular with regional and local businesses that combine managed and on-premises email services. This distribution pattern means that filtering and authentication reputation data for UNAS may reflect primarily regional sender profiles and smaller-scale operations rather than global enterprise benchmarks.

Because UNAS dominates in .hu domains and the smaller-site cohort, its reputation in global filtering lists and recipient ISP databases tends to be driven by the behaviour of Hungarian and regional senders rather than a global average. Organisations sending through UNAS may find that their deliverability varies significantly by geography and recipient ISP: regions and ISPs with heavy Hungarian traffic may treat UNAS-signed mail more favourably, whilst ISPs that do not regularly encounter Hungarian sender patterns may apply generic SaaS provider filtering or require explicit authentication reinforcement (DKIM, DMARC alignment) to establish trust. This regional skew also means that testing email authentication and reputation against global benchmarks may underestimate the real-world reputation of UNAS in its home market.
