Call it the Galentine’s Day revolution, but in a word, “No.” It’s not creepy to send work-appropriate Valentine’s Day greetings to customers and employees. The key is that the card must be focused on customer or employee appreciation. The focus should be on “we love having you as a customer,” or an appreciation message with no mention of Valentine’s Day, but with a design that is appropriate for February. For some companies, not mentioning Valentine’s Day directly is what makes this feel right.
