There is no governing body of card etiquette. There is no test you have to pass. The rules people seem to agree on are mostly inherited from grandparents who learned them from their grandparents, and most of them are sensible — but the ones that have actually survived are sensible because they help the card land. That is the whole job. The card should land.
What follows is the modern, pragmatic version of card etiquette as we have come to understand it after writing several thousand cards and listening to people talk about which ones they kept. It is not exhaustive. It is the part you need.
The four rules that matter
- Use their name. The card opens with their name and ends with yours. Both are non-negotiable.
- Say one specific thing. A memory, a detail, a thank-you for something they did. The card needs at least one sentence that only you could have written.
- Send it. The unsent card is worse than the imperfect one. By a lot.
- Keep it short. A great card is three to five sentences. A page-long card is for a small handful of relationships.
Everything else in this guide is a refinement of those four. If you only remember the four, you will write a better card than 90% of what arrives in mailboxes.
How long after the event should you send a card?
The conventional rule is that you have a window. The window is more permissive than people think. Here is the version that works:
Birthday cards
Aim to arrive a day or two early. Most birthday email and DMs come on the day, so a card sitting on the kitchen counter the night before lands harder. If you miss the day, send it within two weeks. After two weeks, the card becomes a 'just because' card with the birthday acknowledged in passing — that's still good, but the framing changes.
Wedding cards
Traditional etiquette says you have a year. Modern reality is that one to three months feels right. The couple is opening their cards in batches, often when they finally have a Saturday afternoon to themselves. There is no penalty for arriving in week eight. There is a small penalty for not sending one at all.
Sympathy cards
Send it as soon as you hear, but understand that there is no expiration. A card a month later, after the casseroles have stopped and the calls have tapered off, can be the one that lands the hardest. The grieving person is often loneliest in week three. A card in week three says 'I'm still thinking of you' more loudly than one in week one.
Thank you cards
Two weeks is the rough deadline. Inside two weeks, the gift or favor is still warm in the giver's mind, and your gratitude lands as freshly meant. After a month, the thank-you starts to feel obligatory. Still better than not sending one — but the freshness is the reason to be quick.
Get well cards
Send it within the first few days. Recovery is long, but the cards that arrive in the first week are the ones taped to the wall.
Holiday cards
Aim for the first half of December. A card that arrives the day before Christmas competes with twenty other cards. A card that arrives on December 8 has the mantel to itself.
Handwritten vs. typed
The default is handwritten. The exceptions are: very long thank-you notes for a wedding (handwritten still beats typed, but typed is acceptable for the volume), professional cards going to clients in bulk, and people whose handwriting is illegible enough that the recipient won't be able to read it.
If your handwriting is bad, write slowly. Slow handwriting is always better than typed. The bad handwriting is part of what makes it a real letter.
Digital cards: when they work
A digital card is a real card if it is composed with the same care. The medium isn't the issue; the care is. A thoughtful, three-paragraph email on someone's anniversary is a real card. A free Hallmark e-card with a generic preset is not.
Digital cards work especially well for: long-distance friends in different time zones, occasions where the timing matters down to the day, and second cards (the printed one is in the mail; this is a placeholder so you don't miss the moment).
What never to write
There is a short list of phrases that have been written in cards so often that they have lost their meaning. Avoid them when you can:
- 'Sorry for your loss.' It is fine. It is also a phrase the grieving person has now read forty times. If you can replace it with the dead person's name and one specific thing about them, do.
- 'Hope this finds you well.' A card is not an email. Skip the housekeeping intro and just say what you want to say.
- 'Many happy returns.' Unless you are over seventy, this is your grandmother's voice talking, not yours.
- 'Wishing you all the best.' The card will not feel like a card. It will feel like a sign-off in a corporate email.
- 'Best wishes' or 'Best regards' as a sign-off. A card sign-off is a verb. 'Love you,' 'thinking of you,' 'cheering for you,' 'so glad you exist.' Pick one.
How to sign a card
Sign with a verb and your name. 'Love, Ian.' 'Cheering for you, Sam.' 'With love, Mom and Dad.' 'Thinking of you both, Maya.' The verb is the small part of the card that does the most emotional work.
If the card is going to multiple people in a household, list the household: 'Love, the Lindstroms.' If it's a card that only you contributed to, sign only your name. Don't sign your partner's name without checking with them — they may have wanted to add their own line.
Address the envelope properly
Use first and last names. If it's a couple, use both names — 'Sarah and Theo Lindstrom' is more correct, and more modern, than 'Mr. and Mrs. Theo Lindstrom.' If you don't know last names, just first names work for personal cards.
Handwrite the address if you can. A printed label on a handwritten card is fine, but a handwritten address is a small additional kindness.
When you don't know what to write
Stop trying to write. Open a draft and put down two true sentences. They don't have to be good sentences. They just have to be true. Walk away. Come back the next morning, edit them. A card written in two passes is almost always better than a card written in one.
When you forget
You will forget. Everyone forgets. The right move is to send a great card, late, with no apology beyond a single sentence. 'I'm late and I'm sorry — I should have written the day of, but I am thinking of you now and meant every word of this.' Then write the rest of the card as if it were on time. Don't spend three sentences apologizing. The card itself is the apology.
The whole point
Card etiquette is, at its core, a way to make sure your care arrives without being mistaken for performance. The rules aren't there to make you look polished. They're there because, after a few generations of trial and error, certain habits — using their name, being specific, being short, being on time — happen to make care land.
Everything else is style. Your name, your handwriting, your habit of putting a heart at the end. The unique parts are what make the card feel like you. The etiquette is what makes sure the message gets through.
