According to Live Direct Marketing's daily Tranco top-1M scan (July 12, 2026), Autodoc is the SaaS sender for 154 domains — 0.02% of 617,244 SPF-publishing domains. Detection method: include: mechanisms in the SPF record.
Autodoc is a SaaS platform that sends email on behalf of client domains. It provides outbound email infrastructure for organisations seeking to outsource mail delivery, and is typically identified in email authentication records through SPF includes that reference Autodoc's sending infrastructure.
Autodoc's user base is concentrated in the long tail of smaller and mid-market organisations rather than large enterprises, with particularly strong presence across Spanish domains and other European territories. For anyone auditing email practices or evaluating sender authentication, Autodoc's appearance in an SPF record signals the use of third-party email infrastructure—a configuration that demands proper DKIM and DMARC alignment to authenticate messages and preserve sender reputation.

Organisations using Autodoc must declare the service's sending infrastructure in their SPF record, but SPF alone cannot secure email authenticity. DKIM signing must be configured for Autodoc-routed messages, and a DMARC policy should align with Autodoc's authentication path to prevent spoofing and allow receivers to verify that messages genuinely originate from the sending domain. For smaller organisations using Autodoc, which typically lack the accumulated sender reputation of established brands, correct authentication configuration is the primary determinant of inbox placement.

That organisation uses Autodoc as an outsourced email delivery service. To verify the message is authentic, the sending domain should also publish aligned DKIM and DMARC records covering Autodoc's delivery infrastructure.
