Glockapps vs.
Postmastery in 2026

In GlockApps, Microsoft 365 and Google Workspace authenticated cleanly after DNS verification, and the platform separated those streams from SendGrid and Mailchimp once daily aggregate reports arrived. The unknown support desk sender stayed in the unknown bucket until we matched the return-path domain and IP ownership ourselves, which made the source view useful but not fully prescriptive. The SPF pass with visible From mismatch was visible in drilldowns, though deciding whether to approve it still needed operator judgment.

Postmastery gave us fewer adjacent deliverability tools, but its DMARC workflow made the Microsoft 365, Google Workspace, SendGrid, and Mailchimp ownership trail easier to document for stakeholders. The unknown sender classification took longer, but the notes around whether it was an approved support desk path were better for handoff. In the forwarded mail case with SPF failure, Postmastery was clearer about why DKIM domain matching mattered more than the failed SPF hop.

We added the primary corporate domain, marketing subdomain, and parked domain in GlockApps with a short DNS setup path and saw aggregate traffic settle into views by source. Finding the unknown sender required opening IP-level drilldowns and comparing it with the support desk sender, which was workable but repetitive. The forwarded mail SPF failure was shown correctly, but the interface did not turn that edge case into a ready explanation for a nontechnical owner.

Postmastery felt slower during onboarding because the setup path asked us to define domain purpose, expected senders, and ownership before the reports became useful. Once that work was done, the unknown sender review felt more structured, with better notes for whether the source belonged to support or spoofing. The forwarded mail SPF failure was easier to explain because the workflow kept the DKIM result and forwarding context near the recommendation.

GlockApps gave us enough setup help to publish the rua record, verify the three domains, and connect approved senders without a call. The DNS handoff became weaker when the parked domain needed a strict policy plan and when the support desk sender needed owner confirmation. Escalation felt like a product-support motion rather than a guided enforcement program.

Postmastery had the stronger support expectation for enterprise onboarding because the workflow centered owner notes, DNS approval, and change sequencing. The Microsoft 365 and Google Workspace setup needed more up-front conversation, but the support handoff was clearer once SendGrid, Mailchimp, and the support desk sender were documented. Escalation felt slower than GlockApps self-service, but more suitable for teams with formal approval paths.

GlockApps handled the primary domain and marketing subdomain well for an SMB or marketing team, especially where recurring reporting went to the same owner. Account separation was usable but not as clean for MSP-style client work, and the parked domain created extra manual notes because it had no expected legitimate traffic. For enterprise use, the product worked best when an internal owner could translate alerts into DNS tickets.

Postmastery fit enterprise and agency operating models better because it pushed us to group domains by purpose and document source ownership before policy movement. Client handoff was stronger when we needed to explain why SendGrid was approved for the marketing subdomain and why the unknown sender stayed blocked. For SMBs, the same process felt heavier because pricing was not public and recurring reporting assumed more operational involvement.
