Never send an 11 pm birthday text again

The second you think of someone, write their birthday letter and schedule it, up to a year ahead. On the day it lands on their phone at 6 am, the envelope tears open, the confetti falls and your voice plays.

No app for them, no account. 3 free letters every month.

It is 11:58 pm and you just remembered. Again.

A rushed "hbd!!" says you almost forgot, because you did. A letter that has been waiting for their morning, with a photo and your off-key singing, says you thought about them weeks ago.

Birthday letter for a best friend

Happy birthday to my favorite person to laugh with. Another year of late-night talks, terrible karaoke and cake for dinner. I hope today is as loud and as fun as you are.

Birthday letter for mom

Happy birthday, Mom. Thank you for every packed lunch, every late-night phone call and every time you believed in me before I did. I love you more than I say.

Birthday letter for dad

Happy birthday, Dad. You taught me how to fix things, how to tell a joke and how to show up for people. I hope today you get to put your feet up.

Birthday letter for a partner

Happy birthday, love. Another year of you is the best gift I could ask for. Tonight, dinner is on me and you do not have to choose the restaurant.

Big birthday letter

Happy fortieth! Forty looks fantastic on you. Here is to the decade where you finally do all the things you keep talking about. I will be right there with you.

Birthday letter for a grandparent

Happy birthday, Grandma! The kids made you a card, but we wanted you to hear their voices too, so press play. We cannot wait to see you this summer.
