About MailDay
Kids deserve to be
MailDay is a children's pen pal membership built by a homeschool mom who stayed up too late one night and couldn't let an idea go. Here's the whole story.

How this started
I was scrolling TikTok — I know, I know — when I came across a post from a mom. Her third grade daughter was an old soul being bullied by her classmates and her teacher. She was asking the comment section whether to go to the school administration.
And then in the comments, something happened that I couldn't stop thinking about. One mom offered her own daughter as a pen pal for this little girl. Then another. Then another. The comment section just kept going — hundreds of moms trying to find this child a real friend. Strangers on the internet, collectively doing the most human thing they could think of. They couldn't fix the bullying. But they could give her someone to write to.
I have a son just like her. An old soul. The kind of kid who notices what everyone else walks past, who feels things a beat deeper, who's more interested in a real conversation than a crowd. He sees the world a little differently — and it's one of my favorite things about him. That one landed in my chest.
I put my phone down. Fed my daughter. Put my boys to bed. Came back downstairs and opened my laptop.
It was midnight. I was feeding my daughter. I put my phone down and opened my laptop.
"The comment section was full of strangers trying to help one little girl feel less alone. I just thought — why is this so hard to do on purpose?"
I had been running a systems and operations business for eight years — building ClickUp and Slack solutions for remote companies. Good work. Work I was good at. But I had closed it in November when I was pregnant with my third baby because I needed something that felt like an extension of my life rather than a competition with it. I had been looking for what came next.
That night I figured it out.
MailDay is new. I have three children under five, a husband who is a retired boxer from Moldova, and a business I built in the gaps between bedtimes and naps and 2am feeds. It is the most certain I have felt about anything I have ever built.

Kids today are more connected than any generation before them. They are also genuinely known by fewer people than they should be. They have followers and group chats and reaction emojis. What they often don't have is a friend somewhere else in the country who is waiting to hear from them specifically — whose day is a little better because a letter arrived.
A handwritten letter is one of the most quietly countercultural things a child can do in 2026. It requires patience. It requires actually thinking about another person — what they'd want to know, what would make them laugh, what question would make them write back. It is slow by design. The wait is not a bug. The wait is part of it.
MailDay exists because that little girl in the TikTok comment section deserved a friend who'd actually write back — not a comment section full of kind strangers.
We match the kids. We give them everything they need to write. Then we get out of the way and let the friendship happen.
Real connection. Not the simulated kind.

Meet Poppy
Poppy Post is a curious, adventure-hungry red fox who has made it her life's mission to prove that the best things in life arrive in an envelope. Every month she sets off somewhere new — climbing lighthouses, mapping tide pools, befriending a very serious goose — and writes back to her pen pal friends about everything she discovers.
She notices what other people walk past. She's warm, a little dramatic, and never, ever talks down to a child — the kind of character kids genuinely want to be friends with. You'll know her by the oversized scarf and the well-worn leather satchel; she's never without either.
Poppy is not a brand mascot. She is a character with a world. She signs every letter Yours by post, Poppy, and she never breaks character. Every monthly pack centers on her latest adventure — the letter in her voice, the conversation prompts, the drawing prompt, the cutout sheet. She's the thread that holds the whole thing together.
She also has strong opinions about which kids should write to each other. She keeps a clipboard. She takes matching very seriously.
The fox who believes in the mail.
Three years of adventures. Planned from the start.
Poppy's adventures are mapped out three years in advance — a complete arc that grows alongside the children who read them. This is not a subscription that runs out of ideas. Poppy knows exactly where she is going.
Year 1
The World Outside
Poppy explores the big wide world — tide pools and ancient forests and the arctic tundra and the space between stars. Each month connects to a core feeling. By the end of Year 1, your child has traveled to twelve places and felt twelve things, through letters.

The founder
I'm a homeschool mom of three living in Wyoming with my husband, Lazar. We're a multicultural family — two cultures, three languages — which makes our house loud in the best way and never, ever boring.
Before MailDay, I ran SystemsUp for eight years — building ClickUp and Slack systems for remote companies. I closed it in November 2025 when I was pregnant with our third child, because I needed work that felt like an extension of my life rather than something fighting against it.
I homeschool my kids and I think about what it means to raise children who are present, curious, and connected to real people in the real world. MailDay came out of that. Not as a philosophy but as a practical problem with a practical solution: I went looking for a pen pal service for my own kids and couldn't find one I'd actually trust. So I built the one I was looking for.
I am the visible face of MailDay. I believe in building in public and being honest about where things are. Right now MailDay is new and I am one person. That is fine. The best things usually start small.

What we believe
The things we actually stand for.
Real beats fast.
A letter that takes a week to arrive and three days to write is worth more than a message that sends in half a second. We are not optimizing for speed. We are optimizing for meaning. Those are different goals and they produce different outcomes.
The wait is the point.
Anticipation is a feeling children are losing access to. Checking the mailbox every day because something might be there — that is its own kind of good. We did not make the postal service slow. We just think slow is worth defending.
Kids deserve to be known.
Not followed. Not reacted to. Known — by a real person somewhere else in the world who reads their letters and writes back and looks forward to hearing from them. That specific thing. Not a proxy for it.
Analog is a choice, not nostalgia.
We are not trying to go back to anything. We are making a deliberate choice about what kind of childhood we want kids to have access to. A handwritten letter in 2026 is countercultural by default. We think that is exactly right.
That's the whole thing. There is a child somewhere in this country who is curious about your child specifically — who will read their letters carefully and write back something real. We find them for you. You handle the stamps. They handle everything else.
Your kid's pen pal is out there.
