How to write a thank-you note

Almost nobody sends these any more, which is exactly why they land. A thank-you note is four sentences long and takes three minutes, and the two reasons people fail at it are both about delay: they wait until they can write something impressive, and then they are too embarrassed by the delay to write at all.

Send the short one now.

The four sentences

1. Thank them for the specific thing. Not "everything" — the thing.
2. Say what it meant or what you did with it. This is the sentence that separates a real note from a formality.
3. Something personal. A line about them, or a forward look.
4. Close warmly.

Dear Aunty Bisi,

Thank you for the cookbook — I have already made the jollof twice and the second one was almost right. It was so thoughtful of you to remember I had been trying to learn. I hope we can cook something together when I am next in Ibadan.

With love, Chidera

Four sentences. Nothing clever. It works because of "the second one was almost right" — the specific detail proves the gift was used and the note is not a template.

By situation

After a job interview. Email, within 24 hours, to everyone who interviewed you. Thank them, name one specific thing from the conversation, restate your interest in one line, keep it under 150 words. Do not use it to add arguments you forgot to make. Send separate notes if there were several interviewers, and make them different — they compare.

For a gift. Within a week if you can. Name the gift. Say what you will do with it or have done with it. Never mention exchanging or returning it. For money, name the amount only if that is your family's convention, and say what it is going towards.

For hospitality. Within a few days. Mention something specific about the evening or the stay. This is the one where a physical card still has real effect.

For help or a favour. Immediately, and tell them the outcome. Someone who introduced you to a contact very much wants to know whether it worked out — and almost nobody tells them.

For a reference. Twice: once when they agree, and again when you know the result, whichever way it went. This is how people stay willing to be your referee.

For condolences you received. Whenever you are able. Weeks or months late is completely fine, and everyone understands.

Handwritten or email

Handwritten for gifts, hospitality, weddings, condolences, and anything from an older relative. Email for interviews, professional favours and anything where speed matters more than ceremony. When in doubt: email now, and post a card as well if it warrants one. Sent beats perfect.

Common mistakes

Waiting so long that the note becomes an apology. "Thank you for everything" — for what? Writing the same note to five people who will see each other. Turning an interview thank-you into a second pitch. Mentioning that you might exchange the gift. Typing a note that should have been handwritten. Never sending one at all because you could not think of anything good enough.

Practical tips

• Keep cards and stamps in a drawer. The friction is the whole reason people do not send them.
• Write it the same day you think of it.
• One specific detail is the entire difference between a real note and a form letter.
• Late is fine. Say "I have been meaning to write since March" and carry on — do not spend three sentences apologising.
