Behind the envelope
How Emerald Diary works
Every month, a beautifully crafted letter arrives at your door. Here is everything that goes into it.
Three simple steps
You subscribe
Sign up at emeralddiary.com. Tell us your child's name, age, and your delivery address. That's it — we handle everything else.
Wren prepares
Each month, our team researches and writes a new letter from a carefully chosen destination. Every letter is personalised with your child's name.
It arrives in the post
Posted via An Post on the 1st of each month. Your child finds a real letter addressed to them in the post — which is, frankly, magical.
What's inside each delivery
The Letter
1–2 pages written by Wren, personalised with your child's name throughout. Warm, funny, and full of wonder — age-appropriate prose about the destination's culture, geography, and wonders.
World Stamp Card
A collectible illustrated stamp card, one per month. Children build a growing passport collection — each stamp different, each one a keepsake.
A sample letter
Maasai Mara, Kenya — March 2026
Dear [Child's Name],
I'm writing to you from the edge of the Maasai Mara in Kenya, where the grass is as tall as your dad and the sunsets turn the whole sky orange. I arrived yesterday on a tiny plane that bounced three times when it landed (I gripped my seat very tightly, I'll tell you that much).

Until next adventure, Wren 🍀
Each letter is written personally to your child, with their name woven throughout.
Delivery
Letters are posted via An Post on the 1st of each month. They typically arrive within 2–5 working days anywhere in Ireland.
New subscribers receive their first letter within 5 working days of signing up, no matter when during the month they join.
Age guide
Read-aloud
4–6 years
Parents read the letter aloud together — children love listening and looking at the illustrations. The activity is simple and hands-on.
Independent readers
7–9 years
The sweet spot. Children this age can read the letter themselves and are old enough to appreciate the facts and stories.
Deeper content
10–12 years
Letters for older children include richer historical context, more complex geography, and longer activities — challenging without being dry.
