Belated birthday letter for clients

Dear Sam,

Some birthday cards arrive on time. This one arrives with an apology. Your birthday passed last week, and it was only when we were going through our notes that we realized we had missed it. We are truly sorry.

You have been a client of ours for nearly a decade, and in that time you have become part of our story. You were there when we moved into our first proper office. You were patient through a difficult year when our team was stretched thin. And you have always greeted us with warmth, even on the days when we brought bad news about a delay.

That loyalty is something we never want to take for granted, which is why missing your birthday stung.

The letter

Dear {firstname},

Some birthday cards arrive on time. This one arrives with an apology. Your birthday passed last week, and it was only when we were going through our notes that we realized we had missed it. We are truly sorry.

You have been a client of ours for nearly a decade, and in that time you have become part of our story. You were there when we moved into our first proper office. You were patient through a difficult year when our team was stretched thin. And you have always greeted us with warmth, even on the days when we brought bad news about a delay.

That loyalty is something we never want to take for granted, which is why missing your birthday stung.

Your birthday treat is still waiting for you: please enjoy a complimentary session with our compliments, whenever suits you best. We hope your day was wonderful, and we are grateful to have you with us.

With heartfelt thanks,

Make it personal

  1. 1

    Keep the apology light. “A little late, but sincerely meant” is enough. Clients do not need to hear about your busy week.

  2. 2

    Thank them for something real. How long they have been with you, a project you did together, a referral they sent. Specific thanks feels personal, not automated.

  3. 3

    Offer a late treat if it fits. A birthday discount or gift that is still waiting for them makes the message feel intentional, not like damage control.
