The core idea

Email marketing is the disciplined process of sending useful, relevant messages to an audience that can reasonably expect to hear from you.

A simple framework

• Set expectations.
• Write for one reader.
• Match the message to intent.
• Measure opens, clicks, replies, conversions, and unsubscribes.

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.
