<b>Inbox-placement testing: the tools that don't lie to you</b>
Seed tests, spam-folder checks, and what each actually measures.

🧪 Tests
— GlockApps seed-list placement — shows tab-by-tab Gmail placement (Primary vs Promotions), which open rate alone hides.
— mail-tester.com — the free pre-flight; catches auth and content red flags before a real send.
— Google Postmaster Tools — the only direct read on how Gmail itself sees you; seed tests are a proxy, this is the source.
— MXToolbox blocklist check — 30-second scan across major blocklists before you panic about a volume drop.

Picked because together they cover the full chain: content, placement, sender reputation, and blocklist status — no single tool does all four.

Saved you ~2 hours of guessing why opens dipped.
