Don’t just stamp and hope—outsmart the system. First, use bright red first-class stamps (avoid the old second-class blues) and stick them firmly; festive wine spills happen more often than you think.

Second, check the dimensions. A first-class stamp covers a standard letter up to 100g; anything bigger needs extra postage. Overstuffed cards become “large letters,” which can delay your delivery and frustrate the postman.
Third, write the address clearly in block capitals—cursive love notes are charming, but a read-able “12, Holly Lane” is what gets the job done. And please, include a return address; otherwise, your card might end up in the great postal ghost town.
The Parcel Predicament: Boxes vs. Cards
For packages, the rules get stricter. A first-class small parcel cutoff is often the same date as letters, but larger boxes may need Tracked 24 or Special Delivery. A simple rule: if it wobbles or rattles, use extra padding and pay for tracking.
Pro tip: Post early in the day at your local post office—before 12pm gives staff a chance to sort it for the same-day truck. Afternoon drop-offs sometimes sit until the next morning, which is too risky near the deadline.
Don’t forget overseas friends. The last date for international first-class is often two to three weeks earlier, around November 30th for far-flung places like Australia or South Africa. Check the Royal Mail’s “last posting dates” page as if your social life depends on it—because it does.
