Most business Christmas cards are opened, glanced at and put on a shelf. A few are actually read, and occasionally one is kept. The difference is rarely the design or the paper. It is almost always the words inside. Here is how to write a card that a client will remember for the right reasons.
Why the message matters more than the card
A printed greeting with a company signature says “we have a mailing list”. A few handwritten lines that refer to something you did together say “we noticed you”. Clients receive many cards in December, and the ones that stand out tend to share three qualities: they are personal, they are specific and they are short.
You do not need to be a natural writer to manage this. You need a little structure and a willingness to write one card at a time rather than copying the same paragraph forty times.
A simple structure that works
Most memorable client messages follow the same four-part shape. Each part can be a single sentence.
- A warm opening. Use their name, and keep it natural: “Dear Aoife” or simply “Hi Tomás”.
- One specific memory from the year. A project you finished, a problem you solved together, a meeting that went well, a moment that made you laugh.
- A genuine thank-you. Say what you appreciated about working with them, not just that you appreciated it.
- A light look ahead. Something you are looking forward to in the new year, without turning it into a sales pitch.
Then sign off with your own name, written by hand, even if the company name is printed below.

Find the specific detail
The specific memory is what makes a card memorable, and it is also the hardest part to write in a hurry. Give yourself a head start by keeping a short note through the year, or by spending ten minutes looking back through your calendar and project notes before you start writing.
Prompts that help
- What did we work on together this year, and how did it turn out?
- Was there a moment where they made our job easier?
- Did they share news, such as a new office, a team change or a milestone?
- Is there a phrase or joke from a meeting that we both remember?
Even one small detail, such as “thank you for your patience while we reworked the spring brochure”, is more memorable than a full paragraph of general good wishes.
Example messages you can adapt
These are starting points, not scripts. Change the details so they are true for your relationship.
For a long-standing client
“Dear Niamh, another year together, and the autumn launch was a highlight for our whole team. Thank you for trusting us with it and for always being so clear about what you needed. We are looking forward to the plans you mentioned for next year. Wishing you a restful Christmas, Mark.”
For a new client
“Hi Daniel, it has been a real pleasure getting to know your team since September. Thank you for making the onboarding so straightforward. Here is to a good first full year working together. Happy Christmas, Sarah.”
After a difficult year
“Dear Ruth, I know this year asked a lot of everyone. Thank you for your honesty and patience when timelines moved. We learned a great deal working alongside you. Wishing you a peaceful break, James.”
Common mistakes to avoid
- Selling in the card. A festive card is not the place for a new-service announcement or a discount code. Keep it about thanks.
- Copying the same text for everyone. Clients talk to each other, and a repeated line is easy to spot.
- Being too long. Three to five sentences is usually enough. If you need more, it probably belongs in a separate letter.
- Assuming everyone celebrates Christmas. If you are not sure, “Season’s greetings” or “Wishing you a restful end to the year” is warm and inclusive.
- Getting names wrong. Double-check spellings, especially for names with fadas or other accents. It matters to people.
One true sentence about your year together is worth more than a page of seasonal wishes.
Practical details: handwriting, timing and sending
Handwriting is not essential, but it does change how a card feels. If you have many cards to write, split them across the team so each client hears from the person who knows them best. Write in batches of ten or so, with a short break between batches, so the later cards are as fresh as the first.
Aim to have cards in the post at the start of December. That avoids the last-minute rush and means your card arrives while people still have time to read it. For international clients, allow more time and check posting dates with your carrier.
Finally, keep a simple list of who you wrote to and what you said. Next year, it will help you avoid repeating yourself and remind you of the story so far.
Pairing a card with a small gift
For your closest clients, a card can travel with a small gift. The card should still do the emotional work; the gift is a supporting gesture. Something modest and useful, such as a candle, a mug or a tree decoration with a discreet logo, fits naturally alongside a handwritten note. If you are considering this, the Branded Christmas Gifts range from Brandit, an Irish online store, is one place to browse festive items that can be personalised. Prices there are shown without VAT and quotes are prepared on enquiry, so check current details directly.
Takeaway. Use their name, mention one specific moment from the year, say thank you in concrete terms, look ahead lightly and sign it yourself. That simple pattern is what turns a routine card into one a client remembers.
