Best of the inbox: bought-list autopsies
Framing: every link here dissects the same mistake — injecting a purchased or scraped list into a healthy sender. The fixes that earned a spot:

🚀 Deliverability
— The spam-trap density breakdown — picked because it quantifies the risk: even 0.1% recycled traps can flip a domain to junk-only.
— Quarantine-domain strategy — worth your time for the practical move: never mail cold/bought data from your money domain.

🧪 Tests
— Validation-tool bake-off — made the cut for testing ZeroBounce vs. NeverBounce vs. Kickbox on the same dirty file, with catch-rate numbers.

📥 Swipe
— The "how'd we meet" re-permission email — included because re-consenting a sketchy list beats blasting it.

Common thread: consent can't be retrofitted, but damage can be contained.
Saved you ~2 hours and possibly a domain.
