Tips for signing a group card
- Mention the number if you know it. "Five years" makes a message feel personal in a way "another year" doesn't.
- Point to one concrete contribution from their time here: a project they led, a process they fixed, or a person they trained.
- Keep jokes about how long they've been around light. Tease the job, not the person.
- Share the card a few days before the date so people who are out or remote have time to sign.
Celebrate the milestone with the whole team
Start a card, share one link, and everyone adds a message or a GIF from their own phone or laptop. No account for you or for them.

Celebrate how quickly they found their footing and name something they've already contributed. A line like "One year in and you're already the person people ask" works well.
