Birthday Wishes for Your Cousin
Birthday messages for your cousin: the one you grew up with at every holiday, the one you've lost touch with, and the one who's basically a sibling. Short texts, card notes and plenty of family jokes.
Save their birthday and Greetigo emails you the day before, with a message ready.
Use the family history
Cousins have a particular kind of shared memory: the kids' table, the summer at Grandma's, the cousin who always got everyone in trouble. One of those details makes a birthday message feel like it could only come from you.
- 1.Happy birthday, with their name or the family nickname.
- 2.One memory from growing up, or from the last family get-together.
- 3.A plan, or a promise to see each other at the next gathering.
For example: "Happy birthday, Nina. I still think about the summer we built a raft at the lake and it sank in four minutes. Best four minutes of our childhood. See you at Thanksgiving."

"Happy birthday, [name]. I know this year has been hard. I'm here whenever you need to talk, and I mean that."
"Happy birthday. We're grown adults and they still seat us at the kids' table every Thanksgiving. Honestly, it's the best table."
"Happy birthday to the cousin who always got me in trouble and then looked completely innocent. Teach me that face."
"Happy birthday. I found the photo of us in matching outfits at [aunt]'s wedding. I'm keeping it for leverage."
"Happy birthday to Grandma's favorite grandchild. Second favorite. After me."
"Happy belated birthday, cuz. I'm a day late, which is still earlier than you showed up to the last family reunion."
"Happy belated birthday, [name]. I missed the day, but I didn't forget you. Let's get the cousins together soon and celebrate properly."
Text, call or the family chat
For most cousins, a text on the day is right. If your family has a group chat, a message there is nice, but a private text says more. For a cousin you were close to growing up, a call is worth it, even a short one.
If you only see each other at family events
Many cousins drift apart as adults, and a birthday message is an easy way back. Keep it light, mention one memory and suggest one small thing, like a coffee next time you're in the same town.
What to leave out
- Old family arguments, or who said what at the last gathering.
- Comparisons between your parents, or between your kids.
- Embarrassing childhood photos in a public post, unless they'd laugh.

Never miss their next birthday
Cousins share a history nobody outside the family would understand. Use one piece of it in your message, and save their birthday so Greetigo emails you the day before.
Save the date and Greetigo emails you before it. Then pick a free template or, on Plus and Premium, start from an AI-written draft. Send it by email from Greetigo, or copy it into WhatsApp, a text or your own email app. It works in any browser.
