How to personalize a congratulations card for client
Name the achievement specifically. "Congrats on the promotion" is fine; "Congrats on the senior PM role — you've been working toward this for two years" is better. If you played a small part — a recommendation letter, a referral — don't claim credit; let the win be theirs.
When you're writing to client in particular, lean on shared history — a memory you can name, a habit you've watched them keep, a moment you'd both remember. The relationship deserves a sentence the rest of the world couldn't write.
What to avoid
Don't undercut the achievement with a backhanded compliment or a joke about how easy it must have been. Don't pivot the card to your own news. Don't speculate about what they should have asked for instead.
