What to write in a birthday card for your girlfriend
Copy one, mix a few, or let Envelopop draft one from details you share. You can edit every word.
“Happy birthday to the girl who makes my heart do cartwheels.”
“You make every day better just by being in it. Happy birthday!”
“I'm so lucky I get to celebrate you today and every day.”
“Happy birthday, gorgeous. Ready for the best year yet?”
“To my favorite person: may your birthday be as amazing as you are.”

Questions, answered
Can I put their age on the card?
Yes. Add the age they're turning and it appears in the title, like “Happy 75th Birthday, Rose!”. You can edit the title and message any time before you send it.
Can I send it on their actual birthday?
Make it early and set a “Don't open until” date. They'll see a countdown on the envelope until the big day, then it unlocks.
Do they need an app or an account?
Nope. They tap the link and the envelope opens right in their browser, on any phone or computer.
Can I text it or post it?
Yes. Every card can be saved as a GIF or a video, so you can drop it in a group chat, WhatsApp or your stories.
What photos work best?
Clear faces, decent light and one to four people. Old prints work too: snap them with your phone and we'll bring them to life.
