The channel you own.
THE ARGUMENT
Search rankings move. Social platforms change their rules and their reach. An email list belongs to you and reaches people directly.
For most small businesses it is the highest-return channel available and the most neglected.
WHAT IT DOES WELL
Reaching people who already know you Bringing customers back Announcing something to people who want to hear it Recovering abandoned carts Following up after a purchase
WHAT IT DOES BADLY
Reaching new people. Email is for people who already gave you their address.
WHY PEOPLE NEGLECT IT
It requires having something to say, consistently, which is harder than posting.
THE REALISTIC EXPECTATION
A list of a few hundred engaged subscribers is worth more than a few thousand who never open anything.
Growth is slow and the value compounds.
WHERE TO START
Collect addresses properly, send something useful monthly, and measure what happens.
That is the whole strategy for the first year.
