The personalization mistakes that backfire

The personalization mistakes that backfire
Framing line: clumsy merge tags and spun text do more harm than no personalization at all. The fixes worth saving:

📥 Swipe
— Fallback-value checklist — made the cut because "Hi {first_name}|there" leaking raw is an instant trust kill; defaults prevent it.
— The over-personalization creep teardown — picked for showing where "I saw you're from [City]" tips into creepy and spikes complaints.

🧪 Tests
— Spintax-heavy vs. clean-copy placement — worth it: aggressive spinning tripped content filters more than the duplicate-content it was avoiding.

🚀 Deliverability
— Merge-tag QA preflight doc — included to catch broken tags before send, not after.

Lesson: relevance beats trickery; test every fallback.
