What copywriting techniques work well in email?

Classic copywriting techniques translate well to email with adaptation for the medium. AIDA (Attention, Interest, Desire, Action) maps to subject line → opening → body → CTA. PAS (Problem, Agitation, Solution) works for pain-point marketing. Before/After/Bridge shows transformation.

Email-specific techniques: The curiosity gap (open loops that require opening to close). Social proof integration (testimonials, user counts, reviews). Deadline scarcity (genuine urgency drives action). Personalization as proof (\"Based on your purchase of X\"). The PS (often the most-read line after the subject).

Technique serves strategy, not the reverse. Don't apply formulas mechanically. Understand why they work (psychology, persuasion principles) and adapt to your context. A technique that feels forced hurts more than helps. And remember: the best \"technique\" is genuine value. No copywriting trick compensates for an offer people don't want.
