It's the middle of December, your inbox is a disaster zone of "Last Chance" sales, and you’re probably running on three hours of sleep and a lukewarm peppermint mocha. You’ve got a stack of cards on the kitchen counter that you’ve been staring at for four days. Most people think saying thank you and merry christmas is just a polite formality, something we do because our parents drilled it into us or because it's "the season."
But honestly? It’s more than that.
If you look at the psychological data—and I’m talking about actual peer-reviewed stuff from places like the Greater Good Science Center at UC Berkeley—expressing gratitude during high-stress periods like the holidays actually rewires your brain’s reward system. It's not just fluff. When you combine a genuine "thank you" for someone's support throughout the year with the warmth of a "merry christmas," you aren't just sending a greeting. You're reinforcing a social bond that usually frays under the pressure of year-end deadlines and family drama.
The Science of Saying Thank You and Merry Christmas
We’ve all been there. You get a generic text that says "Merry Xmas!" and you barely register it. It’s white noise. However, when someone takes the time to say thank you and merry christmas while referencing a specific moment—maybe that time you helped them finish a project or just listened to them vent—it triggers a dopamine hit for both of you.
Robert Emmons, perhaps the world’s leading scientific expert on gratitude, has spent decades studying this. His research shows that people who practice "active gratitude" report fewer physical symptoms of illness and more optimism. Think about that. A simple phrase can actually make you feel less like you’re coming down with a cold.
It’s weirdly powerful.
The "Merry Christmas" part adds a layer of cultural and emotional tradition. Regardless of your specific religious leanings, the phrase has become a universal shorthand for "I wish you peace and a break from the grind." In a world that is increasingly digital and distant, these five words are a bridge.
Why Specificity Beats Genericity Every Single Time
If you want to actually move the needle in your relationships, stop sending the same "thank you and merry christmas" template to everyone in your contacts list.
People can smell a copy-paste job from a mile away. It feels hollow. Instead, try mentioning one specific thing. "Hey Sarah, thank you for being the only person who kept me sane during the June merger, and merry christmas to you and the kids." See the difference? That’s human. That’s real.

The Harvard Business Review once touched on this in an article about workplace appreciation. They found that employees who received specific, personalized gratitude were significantly more motivated than those who got a generic "Good job, team" email. Apply that to your personal life. Your mail carrier, your barista, your annoying-but-loyal cousin—they all want to be seen, not just "greeted."
The Etiquette of the Modern Holiday Message
Is it "Merry Christmas" or "Happy Holidays"?
Look, this debate gets tired every year. But if you know someone celebrates Christmas, saying thank you and merry christmas is a direct hit of personalization. If you aren't sure, "Happy Holidays" is a safe bet, but the "thank you" part remains the most critical ingredient.
The timing matters too.
Don't wait until 11:58 PM on Christmas Eve. That looks like an afterthought. The "sweet spot" is usually between December 15th and the 22nd. This is when people are still checking their messages but starting to wind down. It's the period of anticipation.
What Most People Get Wrong About Business Greetings
In a professional setting, people often get stiff. They write things like "We appreciate your patronage and wish you a festive season."
Yuck.
That sounds like a robot wrote it in 1995. Even in business, people buy from people. Use a voice. Use a personality. If you’re a freelancer, tell your client, "Honestly, I loved working on that branding project with you this year. Thank you and merry christmas—I hope you actually get some time away from your laptop!"

Digital vs. Physical: Does the Medium Change the Message?
A handwritten note is the gold standard. It always has been, and in 2026, it’s even more precious because nobody does it anymore. When you see a hand-addressed envelope in a pile of bills and junk mail, your heart rate actually changes. You feel important.
But let’s be real: you’re busy.
If you can’t do a physical card, a voice memo is the next best thing. Sending a quick 20-second audio clip saying thank you and merry christmas captures the tone of your voice, the sincerity, and the warmth that text lacks. It’s hard to fake a smile in your voice. Your friends will notice.
The Power of the "Unexpected" Thank You
We usually thank people who did something big. But what about the people who are just there?
- The coworker who always makes a fresh pot of coffee.
- The neighbor who grabbed your trash can when it blew into the street.
- The friend who sends you dumb memes when they know you’re stressed.
Christmas is the perfect "social excuse" to thank these people without it feeling awkward or out of the blue. It’s the one time of year where being "mushy" is socially acceptable. Use that. Lean into it.
Handling the "Hard" Years
Sometimes, "Merry Christmas" feels like a lie. If you’re talking to someone who lost a loved one this year or went through a rough divorce, a standard greeting might sting.
In these cases, the "thank you" part becomes your anchor.

"I know this year has been incredibly tough for you, but I wanted to say thank you for still being such a great friend through it all. I’m thinking of you this Christmas."
That acknowledges their reality while still offering the warmth of the season. It’s empathetic. It shows you’re paying attention. Real expert-level communication isn't about following a script; it's about reading the room and responding with genuine human emotion.
Real Examples of Impactful Messages
Let’s look at a few ways to structure this. Again, no perfect lists here, just some ways you might actually say it.
If you're talking to a mentor: "I was looking back at my notes from our meeting in April. Your advice really changed how I handled the rest of the year. Thank you and merry christmas to you and your family."
If it's for a service provider: "Thanks for always being so reliable with the lawn care this year. One less thing for me to worry about! Have a great Christmas."
If it's a long-distance friend: "I know we haven't talked in a few months, but I was just thinking about that trip we took. Thanks for the memories, and merry christmas!"
Actionable Steps for Your Holiday Outreach
Don't just read this and go back to scrolling. If you want to actually improve your relationships and your own mental state this month, do this:
- Identify five people who made your life easier or better this year in a way that went unacknowledged.
- Pick your medium. If they are over 50, send a physical card or a phone call. If they are under 40, a voice memo or a personalized text is usually better.
- Use the "Specific + Season" formula. Mention one thing you are grateful for, then add your "Merry Christmas" or holiday wish.
- Do it now. Don't wait for the "perfect" moment. The best time to say thank you and merry christmas is the moment you think of it.
- Let go of the response. Sometimes people don't reply because they’re overwhelmed. That’s okay. The act of giving the thanks is where the psychological benefit for you lies.
By focusing on the "thank you" as much as the "Merry Christmas," you transform a seasonal cliche into a powerful tool for connection. It’s the difference between being a name on a screen and being a person who truly matters in someone else's life.
Go make someone's day. It'll probably make yours, too.
