According to Live Direct Marketing's daily Tranco top-1M scan (July 13, 2026), SecuTix is the SaaS sender for 108 domains — 0.02% of 617,702 SPF-publishing domains. Detection method: include: mechanisms in the SPF record.
SecuTix is a SaaS email-sending platform that enables organizations to transmit messages on behalf of their own domains. It is authorized by senders via SPF include mechanisms, placing it in the category of established email service providers and outbound mail carriers.
SecuTix's footprint is concentrated in smaller and mid-market websites rather than enterprise-scale brands, distributed internationally across numerous TLDs with a plurality on .com domains. This pattern is significant for both senders and receivers: senders should recognize it as a legitimate carrier for transactional and campaign mail, authorized via SPF, whilst receivers treating it as infrastructure can calibrate their filtering accordingly. Its frequent co-occurrence with Microsoft 365 suggests a hybrid-deployment pattern, where organizations use M365 for corporate email and SecuTix for customer-facing or bulk traffic.

SecuTix operates as an authorized third-party sender; its presence in SPF records indicates the sending domain has deliberately delegated authority for outbound mail. Recipient mailboxes evaluate SecuTix as infrastructure rather than as a sender identity, meaning filtering decisions are based on SecuTix's sending patterns as a carrier and the domain's own sending practices, rather than on domain reputation alone.
