According to Live Direct Marketing's daily Tranco top-1M scan (July 13, 2026), Alchemer (SurveyGizmo) is the SaaS sender for 233 domains — 0.04% of 617,702 SPF-publishing domains. Detection method: include: mechanisms in the SPF record.
Alchemer, formerly SurveyGizmo, is a SaaS platform for creating and distributing surveys, forms, and feedback campaigns. Organizations using Alchemer authorize its servers to send email on their behalf by adding Alchemer's SPF include mechanisms to their domain records, which ensures that Alchemer-originated mail authenticates as coming from the client's domain.
Alchemer's footprint in email infrastructure is distinctive: it appears across a long tail of smaller and mid-market organizations rather than concentrated among the largest brands. Its usage is internationally distributed, with .com as the most common TLD, and it frequently coexists with Microsoft 365 in hybrid environments. This pattern means Alchemer-authorized email flows from a highly fragmented base of sender domains, requiring recipient systems to assess Alchemer's reputation without the benefit of clear brand consolidation.

Alchemer's presence spans thousands of smaller organizational domains rather than a concentrated group of major brands, which creates a distinctive reputation landscape. Each organization adds Alchemer's SPF include independently, resulting in Alchemer-authorized mail appearing to come from a highly diverse set of domains with no obvious common identity. Recipient systems cannot easily group Alchemer traffic by recognizing a few major senders; instead, they observe distributed flow from many domains, each with its own sender history and authentication posture. This fragmentation can complicate filtering heuristics and make centralized reputation assessment difficult, potentially leading to inconsistent delivery outcomes across Alchemer's customer base.

Alchemer's SPF include typically persists from earlier platform usage that was never removed, because SPF records are not automatically cleaned up when services are discontinued. If you are not actively using Alchemer, you should remove its SPF include to simplify your authentication posture and reduce potential interactions with the platform.
