Email marketing works by turning permission and attention into repeated opportunities to educate, remind, help, and occasionally promote.

The core idea

Email marketing works by turning permission and attention into repeated opportunities to educate, remind, help, and occasionally promote.

A simple framework

• Acquire subscribers responsibly.
• Deliver value before and around promotions.
• Use sequences and broadcasts intentionally.

What to measure

Use outcomes that match your goal: qualified replies, clicks, conversions, sales, revenue per subscriber, unsubscribes, complaints, or customer value. Avoid optimizing a vanity metric in isolation.
