The blind-sending mistake: no placement test

The blind-sending mistake: no placement test
Framing line: checking your own copy in your own inbox proves nothing — you're whitelisted with yourself. Real placement testing is the fix:

🧪 Tests
— Seed-list vs. panel-data comparison — made the cut for explaining why GlockApps seeds lie a little and Google Postmaster + real-recipient panels lie less.
— The pre-send inbox-placement checklist — picked because catching spam-folder placement before the big send saves the campaign.

🚀 Deliverability
— Tab-placement (Promotions vs. Primary) study — worth it: "inbox" isn't binary; the Promotions tab is its own battle.

📥 Swipe
— The litmus-test send to a fresh cohort — included as the cheap canary before full deployment.

Lesson: if you didn't test placement, you don't know placement.
Saved you ~90 minutes of sending into the void.
