<b>Spam-score testing: Mail-Tester vs GlockApps</b>
Before a campaign, you want to know which folder you'll land in. Two tools, two depths.
Mail-Tester is the quick gut-check: send one email to their address, get a /10 score with SpamAssassin breakdown, auth status, and content flags. Free for a few tests/day.
GlockApps is the full lab: send to a seed list across Gmail/Outlook/Yahoo and see actual tab placement (Primary/Promotions/Spam) per provider. Subscription-based.
Pros / Cons
— Mail-Tester: instant, great for content/auth debugging, single-mailbox view
— GlockApps: real per-provider placement, costs money, seed lists aren't your live list
Note: neither predicts placement to a recipient who's never engaged you — that's reputation, not content.
Who it's for: Mail-Tester for fixing a specific email's spam triggers. GlockApps for pre-launch placement across providers.
Verdict: 4.5/5 Mail-Tester for fast debugging, 4/5 GlockApps for provider-level placement. Use Mail-Tester daily, GlockApps before big launches.
