The trouble starts with the words "new role." They sound like a step up, so your brain files the card under congratulations and reaches for the promotion drawer. Or they sound like a departure, because the person is leaving the team you share with them, so your brain files it under farewell and reaches for the goodbye drawer. Both drawers are wrong, and the card comes out sounding like it was written for a different occasion than the one actually happening. A new role inside the same company is its own thing. They're walking into work they haven't done yet, with people who don't know them, while everyone who does know them is still right here. The card has to hold both halves: the unknown ahead, and the fact that you haven't actually lost them.
The two cards people accidentally write instead
Watch what happens when a card goes round for an internal move. Roughly half the signers write a goodbye. "So sad to see you go," "the team won't be the same," "keep in touch." These are lovely sentiments for someone emigrating, and faintly absurd for someone moving to the team that sits by the window. The other half write a promotion card. "Congratulations, so well deserved, you earned this!" Which is great if it was a clear step up, and slightly tone-deaf if it was a lateral move, or a function change where the person is about to be the least experienced person in the room again. Neither half is being unkind. They've just grabbed the closest familiar template instead of looking at what's actually in front of them.
The goodbye is the more common mistake, and it's worth refusing out loud. If the person is still in the building, still on Slack, still going to be in the Tuesday all-hands, a teary send-off card reads as either careless or oddly final, like you're mourning someone who's standing right there. I've watched people read these and not know how to react, because the correct response to "we'll miss you" when you're not going anywhere is a confused thank-you. Don't write the goodbye. You'll see them Monday.
Why "congratulations" can land wrong too
The promotion-card reflex is subtler, because sometimes it's right. If your colleague genuinely got bumped up, congratulations is exactly the word, and our guide to what to write in a promotion card handles that version properly: name the work, not the title. But a new role isn't always up. It can be sideways, the same level on a different team. It can be a fresh start after a stretch that didn't go well, the kind of move HR calls "a better fit" and everyone privately understands. It can be a leap into a function the person has never worked in, where the new title comes with a quiet dread about whether they'll be any good at it.
Write "congratulations!" on that last one and you can land slightly wrong, because you're celebrating an arrival they haven't made yet and aren't sure they'll make well. Congratulations looks backward at a thing accomplished. What this person needs is something that looks forward at a thing not yet attempted. That's the gap the right card fills.
The one true line of encouragement
Here's the move underneath the whole card. Find the specific thing about this person that makes you sure they'll be fine in the new role, and say that. Not "you'll do great," which is the empty version everyone writes. The reason you believe they'll do great. "You're the only person on claims who actually reads the policy before arguing about it, and product is going to be very glad of that" goes to exactly one person and answers the exact fear they're carrying into the move. It says: I've watched you, I know what you're good at, and I'm telling you the thing about yourself that's going to carry over.
This works because a person changing roles is mostly worried they're starting from zero. The kindest, most useful thing you can do is point at the part of them that doesn't reset. The skill, the temperament, the way they handle the hard meeting, whatever it is that's portable. Name it, and you've handed them something to hold on the first morning when the new job feels like a foreign country.
A lateral move or a sideways pivot
When there's no "up" to celebrate, drop the celebration entirely and go straight to interest. A sideways move is often a deliberate, smart choice the person made for reasons that have nothing to do with rank, and treating it like a consolation prize insults it. So don't be falsely thrilled, and don't be falsely sympathetic either. Be curious and be backing them.
"A sideways jump takes more nerve than a promotion, because there's no shiny title to justify it to people, and I think you're going to be so much better suited to this" respects the decision. So does the plainer version: "Different team, same you, and the same you is the bit that matters. Go be good over there." You're not marking a rung on a ladder. You're marking that they chose change on purpose, which is its own kind of brave.
A stretch role they're nervous about
Some internal moves are a stretch: more scope, more seniority, a role the person isn't sure they're ready for and definitely won't admit out loud. The card's job here is to be the voice in their corner that they can't be for themselves. Don't reassure them it'll be easy, because they know it won't, and fake reassurance reads as not understanding the size of the thing. Name the nerves and then name the reason the nerves are wrong.
"You're going to spend the first month convinced they made a mistake hiring you for this, and they did not, and I've watched you grow into every job you've ever been scared of" does the real work. It admits the fear instead of papering over it, then points at evidence. If you've actually seen them do this before, say so: "This is the third time I've watched you take a job that looked too big and then quietly turn out to be exactly the right person for it." That's not a pep talk. That's a track record, handed back to someone who's temporarily forgotten they have one.
A fresh start after a rough patch
Not every new role is a win, and the card that assumes triumph can sting. Sometimes the move is a soft landing after a project that went badly, a manager who didn't work out, a year the person would rather not relive. They know the backstory and so do you, and the worst thing you can do is pretend the reset is purely good news with no history behind it. The kindest move is to skip the fanfare and quietly mark that a fresh start is a good thing to have.
You don't have to name the bad bit. "A clean slate suits you, and this team's lucky to be the one getting the next version of you" acknowledges the reset without dragging up what came before. Or, if you're close enough to be honest: "That last stretch was rougher than it should have been, and I'm genuinely glad you're somewhere new now. Go well." A fresh start doesn't want celebration. It wants someone to confirm, gently, that turning the page was the right call.
When you're staying behind on the old team
If you're the one not moving, there's a small risk your card tips into farewell out of pure habit, because from where you sit the day-to-day really is ending. Catch yourself before you write "we'll miss you," because you won't, exactly. You'll see them constantly. What you'll actually miss is them being on your team specifically, which is a narrower and more honest thing to say.
"It's going to be strange not having you across the aisle, but I'm weirdly pleased I'll still get to wave at you in the kitchen" lands true where a goodbye lands false. Name the specific thing that's changing, not the relationship, which isn't. And then the line people forget, the one that does the most work: make it explicit that you're still around. "Come back down and complain to me whenever the new lot drive you mad" tells them the door didn't close. That matters more than people think, which is the whole next section.
You're their old manager
If you managed this person and they're moving to another team, your card carries weight and needs a steady hand. You're proud, you're a little reluctant to let them go, and you may have had a hand in the move yourself. Don't make it a leaving speech and don't make it a performance review. The best version names one specific thing you watched them become, and makes clear you're still in their corner across the org chart.
"Watching you go from the person who needed every decision checked to the person other people check their decisions with has been the best part of my year, and you're going to be wasted on me anyway" tells them the arc you saw. Then leave the door open, because a manager who stays a reference and a sounding board is worth more than one who waves them off: "You're not my report anymore, but I'm a Slack message away for as long as you need one." For the broader version of writing across that gap, what to write in a card for your manager works the same problem from the other direction.
You're the new team welcoming them in
From the other side, you're not saying goodbye at all. You're saying hello, and a welcome card to someone joining from elsewhere in the company is its own small art. They're not a fresh hire who needs the whole orientation, but they're also not a stranger you can assume already knows your team's particular weirdness. Be warm, be practical, and make the unfamiliar feel survivable.
"Glad it's you we got. The coffee machine hates everyone equally, ask me anything for the first month, and don't believe a word Dev tells you about the staging server" welcomes without ceremony. If you know why they came over, nod to it: "Heard you're the person who's going to fix our reporting, and honestly, thank god." For the fuller treatment of bringing someone aboard, our notes on welcome to the team messages cover the version where the person is brand new to the company too.
The group card when half the signers barely know them
When the card goes round a whole floor, a chunk of the signers will have spoken to this person twice. They shouldn't fake depth, and the organiser shouldn't expect it. One specific, warm line beats a paragraph of manufactured fondness wedged between eleven signatures. From someone who barely knows them, "Good luck on the new team, hope it's everything you wanted" is honest and plenty. From someone who does, that's where the real line goes.
If you're organising it, the first line you write sets the register for everyone after you, so resist the autopilot "good luck!!" and put down something that points forward rather than backward. And gently steer the goodbye-writers away from the platform-waving register; a quick note at the top that says "she's staying with the company, just moving teams" saves half the floor from writing a farewell to someone they'll see at lunch. Our notes on group card etiquette cover the awkward parts, like the people who only sign their name, and how to make a group card everyone signs walks through getting people to actually contribute.
Short, textable, and the "I'm still here" line
Not every one of these needs a paragraph. Sometimes the best version fits in a text the hour you hear. "New role, same desk-neighbour energy. Go get 'em. Lunch this week to debrief?" does the whole job: forward-looking, warm, and it builds the bridge back to you in one line. Keep a few of these in your pocket. "So pleased for you and slightly jealous of your new view." "Onwards. I'll keep your old chair warm in case it goes sideways, which it won't."
Whatever length you land on, the single line people most often leave out is the one that says the relationship survives the move. "Still here" in some form. "You're a floor away, not a world away." "Don't think this gets you out of our Friday coffees." People forget it because the new role feels like the headline, but for the person walking into the unknown, the most reassuring thing on the card is often the proof that not everything is changing at once. Say it plainly and you've written the part most of the card misses.
Turn it into a group card
An internal move scatters the people who'd want to wish someone well in a slightly odd way: the team they're leaving, the team they're joining, the people from across the company who worked with them on one good project years ago and still think of them fondly. A paper card only ever reaches the old team. A single card everyone adds a line to reaches all three groups, which for an internal move is exactly the point, because half the goodwill lives outside the room they're leaving.
A group card online with multiple signatures handles that without a paper card doing laps of one floor. One link goes to everyone, old team and new, each person writes their own line on their own time, and you can create a card online in a few minutes, add a cover photo, and schedule it to land on their first morning in the new seat. The free congratulations ecards page is the quick route if the move genuinely is a step up, and for gathering both teams in one place there's the group card with multiple signers setup. If the move was really a jump to a different company rather than a different team, our guide to what to write in a new job card fits that leap better.
Mireille, for what it's worth, did fine on product. Better than fine. About four months in she sent the whole old claims team a box of those terrible cinnamon bears from the gas station near the office, with a note that said "thank you for the worst card of my life, it taught me a lot." She still parks in the same spot. I bumped into her in the stairwell the week before my contract ended, going up while I was going down, and she just said "told you," which I have thought about more than once since, usually when I'm the one walking into something I'm not sure I can do.
