Everything you need to write the perfect arrival letter, including three ready-to-use templates for different ages.

The morning your elf arrives is the one children remember. Up here at the workshop we send hundreds of scout elves out every year, and the families who make the biggest impression all do the same thing: they send a letter along.
An arrival letter does more than announce your elf. It sets the rules, explains why the elf is there, and gives your child something to hold on to. Here is how to write one, with three templates you can copy straight out.
A good arrival letter covers four things, and it does not need to be long. Children are far more impressed by a short note that sounds like it came from the North Pole than by three paragraphs of careful prose.
Write it by hand if you can. Slightly wobbly handwriting reads as magical rather than sloppy, and it does not look like anything else in the house.
Hello! My name is [elf name] and Santa sent me all the way from the North Pole to stay with you until Christmas Eve. I am very small so please do not pick me up, or my magic goes fuzzy. I will find a new spot to sit every morning. See if you can find me! Love, [elf name].
Short sentences, one instruction, and a game to play. That is all a three-year-old needs.
Dear [child name], Santa asked me to come and stay with your family this Christmas. My name is [elf name] and I have worked in the wrapping department for 112 years. Every night I fly back to the North Pole to tell Santa how things are going here, and every morning I come back and find somewhere new to sit. There is one rule: elf magic does not survive being touched, so please look but do not hold me. I am staying until Christmas Eve, when I fly home with Santa. I am very glad to be here. Your friend, [elf name].
Older children enjoy detail. A job title and a number of years give the elf a history, and history makes a character feel real.
Surprise! Santa decided one elf was not enough for a family this busy. My name is [elf name] and I am here to help [first elf name] keep up. We do not always agree on where to sit, so do not be surprised if things get a little silly. Same rules as before: no touching, and no telling anyone at school that we move. See you in the morning! [elf name].
Let the child name the elf if they are old enough to want to. An elf called Bob because your four-year-old likes the name Bob will be loved far more than one you named yourself. If they are stuck, the classic North Pole naming pattern is a Christmas noun plus a soft ending: Tinsel, Sparkle, Cocoa, Pepper, Jingle.
Somewhere it will be found without being searched for. Taped to the elf, propped against the cereal box, or sitting on the child's usual chair all work. Under a door or inside a drawer means a letter discovered three days late, when the moment has passed.
This is the part parents get wrong most often, and it is worth being honest about. Whatever the letter promises, you have to deliver every single morning for weeks. If the letter says the elf gets up to mischief, you have committed to mischief.
Write a letter that promises a new hiding spot and nothing more. You can always add extra later. Scaling back is what children notice.
Some families pair the arrival letter with a message from Santa himself, so the elf is introduced by the person who sent them. A short video call where Santa mentions the elf by name lands very well with children who are starting to ask questions, because it puts two pieces of the story together.
If you would like Santa to introduce your elf personally, you can arrange that through Chats with Santa.
The arrival letter is the smallest amount of effort for the biggest return in the entire elf tradition. Ten minutes with a pen buys you weeks of a child who believes something extraordinary is living in their house.
Keep it short, keep the promises small, and let the wobbly handwriting do the work.
