Hints & Tips

Need some advice on writing perfect client birthday wishes? To start on the right foot, check out the hints and tips below.

What's the right way to write client birthday wishes?

What type of client birthday wishes should you write in your customer's birthday card?

Overall, you need to be professional to a certain extent, but you also have to be sincere, striking the perfect balance to write appropriate birthday wishes that make your clients feel special on their big day. 

Writing client birthday wishes is not as simple as it may seem. Even if you write what I call "safe" birthday messages, you may inadvertently offend your customer. So what kind of client birthday wishes should you write?

If your clients expect the personal touch, writing one-size-fits-all client birthday wishes will just seem disingenuous to them. Keep in mind that most clients think they're doing you a favor by giving you business. In turn, many expect some level of gratitude mixed into your client birthday wishes.

To help you write the appropriate choice of words, below are different types of client birthday wishes you should use based on the kind of clients you may have. See a list of the type of clients out there nowadays:

  • The Passive-Aggressive: Write clever, happy or cool client birthday wishes.
  • The Family Friend: Write cute, sentimental or happy client birthday messages.
  • The Under-Valuer: Write happy birthday greetings.
  • The Nit-Picker: Write clever or cool client birthday wishes.
  • The Scornful Saver: Same as above.
  • The “DIYer": Opt for inspirational, funny, cool or clever client birthday wishes.
  • The Control Freak: Take the clever or cool birthday message route.
  • The Dream Client: Go for cute, inspirational, sentimental, funny or happy birthday wishes (any type you want, basically).

The hints and tips above are only suggestions. You know your customers best, so you are the best judge of what's appropriate as client birthday wishes.

Personally, I like client birthday wishes that express a thought that most clients want to hear some (not all) of the time: you are special, not just because you give me business but because you are a great person to work with.

If all else fails, keep this rule of thumb in mind: write client birthday wishes as a concrete, personal (but not too personal) way to express your gratitude for their business.
