"Reminder sent to" means people in those countries get a notification at 10:00 local time on the holiday. Anyone, anywhere, can earn the stamp.
How to get one
- Send one letter in the window — a floated letter, a reply or an intro letter all count.
- Wait about 10 minutes — stamps are added every 10 minutes. There's no separate notification.
- Put it on a letter — choose the stamp for your next letter. Letters take 1–24 hours to arrive depending on distance, so to have a letter arrive on Christmas, send it around Christmas Eve.
Good to know
- Picture stamps show as pictures in app version 2.0.18 and later; older versions show the season stamp.
- Collect three different holiday stamps to earn the "Holiday Collector" passport title.
- Other ways to collect stamps are in Lettie stamps.
Dates are the server settings as of October 18, 2026; the World Post Day count is Lettie's own.
