Step one: Stop lying to yourself. You are not going to mail it “next week.” You will mail it at 4:59 PM on the last day, sprinting to the post office in sweatpants. Step two: Write the date down now. On your phone. On your fridge. On your arm if you’re desperate. Step three: Consider using First Class if it’s important. But if you must use Second Class, pretend the last posting date is three days earlier than it actually is.
Also, here’s a pro tip from someone who’s been burned: avoid the December rush. That’s when the postal system goes into “I’m a angry bear” mode. The last posting date for Second Class during the holidays is a myth—it’s more like a suggestion. Mail your Christmas cards in November. You’ll feel smug. Your relatives will be confused but pleased.

But what if I miss it?
Relax. You won’t be fined. You won’t go to mail jail. (Though there should be a court for chronically late mailers—I’d be the judge.) Your letter will just go on a vacation.
It’ll sit in a sorting facility, flirt with a package from Ohio, and then show up a week later with a “Sorry we took so long” sticker. Honestly? That sticker is more sincere than half the cards I send.
