Common questions

Is it appropriate to send a funny birthday card to a client?

Generally, yes, if you know your client well and have a friendly rapport. Gauge their personality—if they've shared jokes or casual banter before, a light-hearted, professional funny wish is a great choice. Avoid anything offensive or overly personal. When in doubt, lean slightly more professional than risky.

What should I avoid in a funny birthday message for a client?

Avoid jokes about age (if they might be sensitive), anything related to work performance or deadlines in a negative way, sarcasm that could be misread, and overly informal slang. The humor should be warm, inclusive, and celebrate them—not make them the butt of the joke. Keep it clean and positive.

Should I handwrite the card or send an e-card?

A handwritten card in the mail often has a more personal, thoughtful impact and shows extra effort. An e-card is perfectly acceptable, especially for last-minute wishes or if you only have an email address. Choose based on your relationship and timing. The key is the message itself—make it genuine and tailored.
