As the UK swelters in temperatures that rival record highs, Christmas might be the last thing on anyone’s mind. But this week marks Leon (Noel spelt  backwards – yes it’s really a thing!) Day – 25 June, exactly six months before Christmas – and for smart organisations, it’s the perfect reminder that festive campaign planning starts now.

While consumers are enjoying the summer, marketers, fundraisers and retailers know that successful Christmas campaigns aren’t created in November. The most effective campaigns are built on early planning, giving teams time to develop creative ideas, refine data, secure production capacity and coordinate activity across channels.

For organisations using the mail, getting ahead is particularly important. Peak season places huge demands on production schedules and delivery networks, and leaving things too late can mean higher costs, reduced flexibility and unnecessary stress.

Early planning also creates opportunities to test messaging, segment audiences and ensure data is up to date before the busiest period of the year. Investing time now pays dividends later.

Christmas remains one of the most important periods in the marketing calendar, and physical channels continue to play a vital role in creating memorable experiences and driving response.

So, while the weather may say summer, Leon Day is a timely reminder that the countdown to Christmas has already begun. The organisations that start planning today will be the ones best placed to deliver standout campaigns when December arrives.

So for help on your Christmas 2026 activity get in touch – it is never too early!
