How long should my message in a group card be?

One to three sentences covers most relationships and most occasions. Go longer only for sympathy notes from a real friendship, milestone retirements or birthdays where you have known the recipient ten or more years, or close-collaborator farewells. Go very short, or skip signing entirely, for cards where you barely know the recipient. Length should match the actual relationship, not the social pressure to look thoughtful.

What do I write in a group card for someone I barely know?

One short specific honest line. 'Best of luck on the new chapter' with your name is fine. If you want to go slightly warmer, name one real small thing you have noticed about them ('your slides are always the cleanest in the all-hands'). What you do not do is fake closeness; 'we will miss you so much' from somebody who has met them twice reads as performative, and the recipient can tell.

Is it okay to not sign a group card I was invited into?

Yes. A missing signature is almost never noticed by the recipient, and is always better than a fake one. The cards where this comes up most often are the wide-net team or org cards where you got pulled in because somebody invited the whole channel. If you genuinely have nothing to write, just close the tab. The organizer is not tracking who signed.

Should I match the tone of the messages already on the card?

Yes, roughly. Scroll through the first few notes before you write your own. If the existing notes are short and professional, the organizer is going for workplace-warm, and a paragraph from you will look out of place. If the existing notes are longer and warmer, you have room to go longer too. Match the organizer's first message, which is usually the implicit instruction sheet for everyone else.

What is the worst thing to write in a group card?

An undirected greeting with no name and no specific detail ('Happy Birthday!' on a colleague's card). Close runner-up: the corporate kiss-up paragraph that flatters without saying anything specific. Recipients can tell the difference between a message written for them and a message written for any vaguely-warm occasion. The former gets remembered; the latter blurs into the scroll.

Can I write something funny in a group card?

Yes, if the relationship and the occasion support it, and if the joke works without the inside-joke context. Group cards are read out loud at goodbye lunches or shared with the recipient's partner that evening; a joke only you and the recipient understand will make everyone else in the room feel locked out. Keep the warmest inside jokes for a separate one-on-one note. The group card is the public version.

How to Sign a Group Card (+ What to Write)

Daniel Pierce

May 26, 2026

A coworker two desks over named Priya sent me a Slack DM on a Thursday in March asking me to sign a baby-shower card for a woman on the marketing team I had spoken to maybe four times, two of those in a Zoom waiting room. I clicked the link. The card opened. The blank text box stared back at me. I sat on it for ten minutes. I typed 'congrats!' and then deleted it because it felt thin even by my own low standards. I typed 'wishing you and the little one all the best' and deleted that too because it sounded like the bottom of a Hallmark in the grocery checkout. I closed the tab and went to lunch. I came back and signed it with one specific sentence about a meeting where she had asked a question that had saved my team a week of work. It took eight more minutes. This is the experience nobody writes about, because almost every article about group cards is written for the person who built the card, not the person staring at the blank box. This one is for the box-starer.

One thing worth saying up front: your message does not have to be long, and it does not have to be clever. The worst messages in any group card are the ones that could have been written about anybody. 'Wishing you all the best' applied to a baby shower, a farewell, a sympathy moment, and a retirement is the same sentence in four different costumes, and it lands as filler in every one. This guide is about what you actually do with the blank box, broken out by relationship, with examples and a list of the things people put in those boxes that should never have been written.

First, read the room: scroll the card before you write

Almost every group card you sign is going to be partially full when you open it. Three or five or eleven people have already written something. Scroll through what is there before you start drafting your own. Those messages are doing the work of telling you what the register of this specific card is. If the first three notes are two-sentence professional well-wishes with no jokes, the organizer is shooting for a workplace-warm card, and your inside-joke-about-the-trivia-night is going to look out of place. If the first three notes are paragraph-long with crying emojis at the end, you have room to go longer and warmer than you would have otherwise.

The signal I rely on most is the length of the first message, which is usually the organizer's. Organizers sign first. Their message is the example for everyone else. A four-line organizer message means the card is built for the longer warm format; a one-liner from the organizer means the card is built for quick signatures from a crowd. Match the length, more or less. You can be a little longer or a little shorter. Going three times longer than the organizer is the move that makes your message look way out of place compared to everybody else's.

Name the relationship before you write a word

Most bad group-card messages come from people who did not stop to ask themselves which relationship they are actually writing from. The answer is rarely 'we are close', because if you were close, you would be sending a one-on-one card. As a quick aside on length: one to three sentences covers most of these, and the only times you should be writing a full paragraph are a sympathy note from a real friendship, a milestone retirement after ten-plus years together, or a close-collaborator farewell where you have actual stories. Everywhere else, three sentences is plenty. Anyway, the tier you are usually picking from is one of these:

Close coworker or close friend. You have actually worked on real things together, or spent hours together outside of work. You can name specific moments. Write two to four sentences, mention a real one, sign off warmly.
Friendly acquaintance. One or two sentences, one specific detail.
Barely know them. You are in the channel, you know their name, you have maybe nodded at them in the office kitchen. Write one short specific line about something real, even if small, and sign off briefly. Do not pretend to a closeness that is not there.
Total stranger who got pulled in by accident. The card got sent to a wider list than the organizer intended and you happen to be on it. You can either decline to sign (totally fine, no message is better than a fake one), or write a one-line good wish that is honest about not knowing them well. 'Best of luck on the new chapter, even though we have not gotten to work together yet' is fine. 'I will miss you so much' from somebody who has never met them is not.

Pick which one you are before you draft anything. The line you would write for a close friend reads slightly insulting on a card for somebody you barely know, because they are going to feel the gap between the warmth in the words and the absence of warmth in the actual relationship. I will admit I have signed cards with 'Best!' and my name more times than I want to count, including twice in the same week last fall on cards for people I actually do know reasonably well, so the advice in this article is more aspirational than I would like.

What to Write: Examples Across Registers

What follows are real-shaped messages, grouped by relationship type. Steal directly, adapt freely, or use them as a starting point and write your own. None of these are filler.

For a close coworker (you have actually worked with them)

Going to miss you.
Working on the Q3 release with you was the most fun I have had on a project in two years. Going to miss the daily standup chaos. Take care of yourself out there.
You taught me how to push back in a one-on-one without burning the relationship, and the specific moment I remember was that thing in late February where you let me sit in the room and watch you do it with the VP (and then debriefed me afterwards over coffee, even though you had a 2pm) — I am going to keep using that skill for the rest of my career. Happy birthday.
Thanks for staying late on the night of the launch in March and rewriting the deployment script after I broke it. I never properly said it then. Saying it now. Have a great last day.
You ran point on the messiest project of last year and somehow made it look not-messy. The team noticed. I noticed. Congratulations on the promotion.

For a friendly acquaintance (you know each other, not closely)

Best of luck.
Glad we got to work on the strategy doc together back in February. Have a great new chapter, whatever it ends up being.
You always asked the question in the all-hands that the rest of us were too polite to ask, and I want to specifically call out the one in October where you pushed back on the roadmap slide that nobody else was going to push back on (which I think genuinely changed the direction of the next quarter, or at least changed the conversation about it) — we need more of that. Best of luck on the next thing.
Happy birthday from the desk three rows over. Hope today involves cake and zero meetings.
Welcome to the team. I have heard good things from your old manager. Looking forward to working together.

For a coworker you barely know

Good luck out there.
Best of luck on the new role. Hope the new team realizes what they got.
We have not gotten to work together much, but I have heard from people I trust on the team that you are the kind of person whose calendar is worth fighting to get on, and I am sort of kicking myself for not engineering more excuses to grab coffee while you were here (next time, maybe — assuming there is a next time, which the way things go in this industry, who knows). Good luck with the move.
I do not know you well, but your work on the onboarding doc made my first month here a lot less terrifying. Thanks for that.
Congratulations. I hope the new chapter is everything you hoped it would be when you decided to make the jump.

For sympathy or hard moments

I am so sorry.
Thinking of you and your family this week. No need to reply. Just wanted you to know.
I do not have the right words. I just wanted to add my name to this card so you know I am thinking of you.
I lost my dad three years ago and the only thing anybody said that helped was 'this is not going to feel okay for a long time, and that is the right response, and we are here when you want company.' I am passing the line along because it was the only one that landed for me in the first few weeks, and not the eight or nine other very kind notes I got that meant well but did not have anywhere for me to put them. I am here when you want company.

For a baby shower, wedding, or other 'congrats' moment

So happy for you.
Congratulations to both of you. Wishing you all the chaos and joy and zero-sleep nights you signed up for.
Welcome to the parent club. Nobody knows what they are doing. You will be fine.
The way you light up when you talk about the wedding plans has been the best part of the team off-sites for the last six or seven months, and I am not the only one who has noticed (the running joke in our 1:1s with your manager is that the wedding-planning Q4 OKR was secretly the most ambitious one on the team). So happy for you. Have a real party.
Congrats on the engagement. Calling it now: you are going to have a great party and a great rest-of-your-life.

The things people write that should not be written

These are real categories of bad group-card messages, observed across roughly a hundred cards I have read in the last few years as both organizer and signer. Avoid all of them. If your draft looks like one of these, rewrite it.

The undirected greeting. 'Happy Birthday!' with no name, no detail, and no sign-off. It looks like you were tagged in a group photo and signed a school yearbook on the way past. The recipient will read it and forget it inside ten seconds. If you genuinely do not know them well enough to write a real sentence, write the one short specific honest line from the barely-know-them tier above. Or, honestly, do not sign. A missing signature beats a placeholder signature.

The message that sounds like a LinkedIn comment. 'It has been such an honor and a privilege to be your colleague and to learn so much from your leadership.' This is what people write when they are signing a card for somebody two levels up that they do not actually know and they are afraid of being too informal. The reader knows. The reader can always tell. Recipients of these messages, in my experience, read them and feel slightly insulted by the implication that they are the kind of person who wants to be flattered by strangers. Pick one specific thing instead, even small. 'I appreciated the way you ran the all-hands in February without slide thirty-six' beats 'It has been a privilege to learn from your leadership' on every dimension a recipient cares about.

The inside joke nobody else gets. Group cards are read by groups. The recipient often reads them out loud at a goodbye lunch or shares them with their partner that evening. An inside joke that only the two of you understand makes everybody else in the room feel locked out, and makes the recipient feel slightly weird about being the only one in on it. If the joke is essential to the relationship, send it in a separate one-on-one note. The group card is not the place. The group card is the public version.

The reused message you already wrote on the last card. If the recipient is on your team and you have signed three group cards for the team in the last six months, please do not write the same fundamental message four times. Recipients compare, sometimes. So do the other signers, sometimes (especially if the organizer is going to print the group card as a keepsake, in which case the recycled message is literally going to be paper next to the original). Recycled paragraphs read as low effort even when the original was good.

The unsolicited career advice. Especially on a farewell card. The leaving person does not want, on their last day at their old job, your three paragraph thoughts on what they should look for in their next role. They want to be sent off warmly (if you want a longer reference for warm-but-not-career-advice farewell lines, the piece on farewell messages for a coworker has a few dozen organized by relationship). Save the advice for the LinkedIn message you can send them in three months once they have settled in.

The 'we will miss you' from somebody who will not. If you barely know them, do not claim to. 'We are going to miss you so much' written by somebody who has met the recipient twice sounds fake, and the recipient will know you do not actually know them. The relationship-appropriate version is 'Best of luck on the new chapter; sorry we did not get to work together more directly.' Both honest and warm.

When you genuinely do not know what to write

This happens. You got pulled into a card for somebody two teams over because their manager invited the whole org and you do not actually have a single specific thing to say about them. The honest play, in descending order of preference:

Decline gracefully. Do not sign. Nobody is going to scroll through and notice you specifically did not. A missing signature beats a fake one every time.
If you feel social pressure to sign anyway, write the one short specific honest line from the barely-know-them tier. 'Best of luck on the next chapter' with your name is fine. It is honest. It is brief. It does not pretend to a relationship that is not there.
If you really want to add something warmer, name one thing you have actually noticed about them, even if small. 'Your slides are always the cleanest in the company-wide all-hands; that is a real skill' is a specific honest compliment from a near-stranger, and it lands warmer than a paragraph of fake closeness would.

The thing that almost never works: copying a message somebody else wrote, with the names changed. The recipient reads them in sequence and the duplicate stands out. The other signer notices. Just pick one of the three options above and use it.

Turn it into a group card you would actually want to receive

If you are the one organizing the card, the single best thing you can do for your signers is write a first message that sets the register clearly and gives them a specific moment to model. Your message is the example for everyone else; vague openers get vague responses. A group card online with multiple signatures works as a coordination tool only if the organizer treats the first message as the example, not the throwaway.

You can create a card online in a couple of minutes, and for workplace farewells specifically a virtual farewell card in board layout holds twenty or thirty signers gracefully.

If you are on the organizer side and want the longer walkthrough of the build, the piece on how to make a group card everyone signs covers the PIN mechanic, the channel-selection question, and the chasing-non-responders policy. And if you are signing a card for somebody leaving and want a longer reference of register-appropriate lines, what to write in a goodbye card is the one I send to people who DM me asking for help.

One last thing, unrelated and probably only useful to me. I noticed last weekend, going through a shoebox in the closet at my parents' house, that my handwriting changed sometime around 2018 or 2019 and I have absolutely no idea why. There is a birthday card I wrote to my grandmother in maybe 2014 where the cursive looks like it belongs to a teenager who is trying — the letters are taller, the loops are bigger, the 'g' has this weird curl at the bottom. By the time I am writing in 2020 it has gotten smaller and more sort of cramped, less performance, more shorthand. Probably this is because I stopped writing physical cards more or less entirely around the time everybody else did. I cannot remember the last time I sent a handwritten letter. The thing I found weirdest in the shoebox was a card from a coworker I worked with in 2007, a guy named Ted, who I cannot place at all. The card says 'best of luck on the move!' in pen, signed with his full name, and I have no recollection of leaving any job in 2007 or of knowing a Ted. My mother has kept this for almost twenty years. I am going to ask her about it the next time I am over. Anyway. Sign your cards.
