Staring at a blank thank you card, unsure what to write, is one of life's small recurring stresses. The trick is that a thank you note doesn't need to be long or clever — it needs to be specific and sincere. In fact, there's a simple formula that etiquette writers have used for generations, and once you know it you'll never be stuck for words again. Here's what to write in a thank you note, line by line, with wording ideas and examples.
A short, well-judged note usually has four moves:
Four sentences. That's a complete, heartfelt thank you note.
For a gift "Thank you for the [gift] — it was such a thoughtful choice, and I'll think of you every time I use it."
For hospitality "Thank you for having us for dinner. The food was wonderful, but it was the company that made the evening."
For a kind gesture "Thank you for [what they did]. It made a real difference at exactly the right moment, and I'm so grateful."
For a wedding or big event "Thank you so much for celebrating with us and for your generous gift. It means the world to have had you there."
Be specific. "Thanks for the gift" could go to anyone; "thank you for the hand-painted mug — it's on my desk and it makes me smile every morning" could only go to one person. Naming the gift and saying one true thing about it is the difference between a note that feels dutiful and one that feels warm.
Follow the four-line formula: thank them for the specific thing, say something nice about it, add a personal or forward-looking line, and close warmly. Four sincere sentences are plenty.
A note is short and casual — usually a card — and perfect for gifts and social occasions. A letter is longer and more structured, better suited to interviews or formal gratitude. For the longer version, see our guide on how to write a thank you letter.
Almost never. Aim for within a week or two, but if more time has passed, send it anyway with a brief, honest acknowledgment. People are far happier to receive a late note than none at all.
For personal occasions, handwriting adds warmth and is well worth the effort. That said, a cleanly printed note is completely appropriate — especially if your handwriting is hard to read or you're sending several at once.
With the four-line formula and a specific, sincere touch, "what do I write?" stops being a problem. If you'd like your notes to look as thoughtful as they read, the Letter app lets you format and print a clean thank you note from your phone or computer — so you can send genuine gratitude without hunting for the right card.
