The Site Diary — one useful email a week
One construction concept explained properly, one template you can use on Monday, and one free tool. No spam, no daily digest, no growth-hacking. Unsubscribe in one click.
What arrives
- One concept, explained. Lap length, bulking of sand, why a BOQ rate is front-loaded — the formula, then a worked example.
- One template. A checklist, register or certificate you can put to work the same week.
- One tool. Usually one of our free browser calculators, occasionally something we did not build.
What does not arrive
- Daily emails. It is weekly, and only when there is something worth sending.
- Your address in anyone else's hands. We do not sell, rent or share subscriber lists.
- Dark patterns. The unsubscribe link is in every email and it works immediately.
See our privacy policy for how subscriber data is handled.
