Seed-list placement tests vs reputation monitors

Seed-list placement tests vs reputation monitors

Two different ways to answer 'am I inboxing?' — and people confuse them.

Seed-list tools (GlockApps, Mailreach inbox placement)
— Pros: send to a panel of real Gmail/Outlook/Yahoo seeds, show exact folder per provider
— Cons: seed accounts have no real engagement, so results skew optimistic vs your actual list

Reputation monitors (Google Postmaster Tools, free)
— Pros: real domain/IP reputation from Google's own data, spam-rate trend
— Cons: Gmail-only, needs DMARC + volume to populate, lagging indicator

The honest workflow: use Postmaster Tools as your ground truth for Gmail reputation, run a GlockApps seed test before launching a new domain or after a placement scare, and never trust a single test as gospel.

GlockApps
— Pros: multi-provider folder breakdown, blacklist + auth check bundled
— Cons: per-test pricing, optimistic seeds

Verdict: 5/5 Google Postmaster (free, real data) + 4/5 GlockApps for spot-checks.

Who it's for: senders who want to know placement before the campaign tells them.
