Email remains the highest-ROI channel for most UK small businesses — typically £40+ back per £1 spent. Here's how to build a newsletter people open, click and buy from.

List growth that compounds

One opt-in offer (a genuinely useful PDF, checklist, or discount), one homepage signup, one footer signup, one popup. Beyond that, growth comes from content distribution, not popups.

Cadence and content mix

Weekly beats monthly for engagement. 80% useful content, 20% offers. The "useful" half can be one insight, one story and one link.

Deliverability fundamentals

Set up DMARC, SPF and DKIM. Clean inactive subscribers every 90 days. Use a real reply-to address. Most UK small businesses lose 20–30% of opens to inbox-tab placement they could fix in an afternoon.

Tools

Mailchimp for general, Klaviyo for ecommerce, Buttondown or beehiiv for creators.
