Social reach is rented and shrinking; your email list is owned and portable. Pound for pound, email still out-earns every other digital channel - yet most small businesses either send nothing or a guilty newsletter twice a year. Here is the starter version done right.
Permission first - UK GDPR is not optional, and bought lists poison your sender reputation anyway. Earn addresses: a discount on first order, a genuinely useful guide, early access for regulars. Collect at the till, on the website, at the point of quoting. A hundred real local customers beat ten thousand strangers.
Monthly is plenty to start. The formula that works: one useful thing (a tip, a how-to, an answer to a common question), one human thing (new team member, behind the scenes), one commercial thing (offer, new product). Subject lines win or lose the open - specific beats clever.
A welcome email when someone joins (highest open rate you will ever get - use it well) and, for shops, the abandoned-basket reminder, which quietly recovers real revenue every week. Both are set-and-forget. Our e-commerce platform includes them out of the box, and we set up email capture on every site we build.
