According to Live Direct Marketing's daily Tranco top-1M scan (July 13, 2026), Logix InfoSec is the email service provider (ESP) for 118 domains — 0.02% of 617,702 SPF-publishing domains. Detection method: include: mechanisms in the SPF record.
Logix InfoSec is an email service provider (ESP) that publishes SPF include mechanisms used by smaller and mid-market organisations to authorise outbound email sending. The service is found predominantly across the .com namespace and in the long tail of domain adoption rather than among the largest commercial brands.
Because Logix InfoSec's footprint is concentrated among smaller sites, it is unlikely to be a primary testing priority for major senders. However, anyone receiving email from smaller commercial domains, or conducting comprehensive infrastructure audits of sender authentication, may encounter its SPF records and should be able to assess whether its includes are correctly configured.

Logix InfoSec publishes an SPF include mechanism that smaller domains use to authorise mail sent through its infrastructure. When properly configured, the domain's SPF record contains Logix InfoSec's designated include string, which resolves to authorised IP ranges for outbound mail. Misconfigured or missing SPF includes—or includes that fail to resolve—can result in mail being rejected or flagged as unauthorised, even if the underlying sending infrastructure is legitimate. Verifying correct SPF syntax and include resolution is essential when auditing sender authentication for domains using Logix InfoSec.
