How to write it

A birthday message for a coworker should be friendly and appropriate, and these examples are both. Most coworker cards fall flat because they are too generic. "Have a great day" could be from anyone in the building. A sentence about the project you finished together, or the way they make Monday meetings bearable, tells them you noticed, and that you cared enough to say so.

Keep the tone suited to your office. A light joke can be fine on a casual team. In a more formal one, a short, sincere line is safer. Pick a message below and add one detail from your actual work together, so it does not read like it came off a pile of cards. Your message prints on a postcard in a handwriting-style font, and we mail it for you.

Mention one concrete thing they did, such as a project, a favor, or a good call. Specifics sound sincere.
Avoid jokes about age, appearance, or personal life. Aim for a compliment you would be comfortable saying out loud in the hallway.
Keep it to two or three sentences. A longer note can feel like too much for a work relationship.
If the card is from a team, have everyone add a line to one message instead of mailing several.
Mail it to their home if you are sending a card to someone remote or on leave. It feels more thoughtful.
