Choosing and sending this card
An 18th is a big one. Send the link as soon as you know the date, not the week before, so everyone has time to sign.
If the group is large, add a note saying who the card is for. Not everyone will recognise the name from a link alone.
Check the opening date when you set up the card. It should open the morning of the birthday, not the day after.
How it works
One card, one link, opens on the day.
- 01
Set the date.

Send the link.
Friends, family, old teachers. Each person signs once, from any browser.
- 03
They open it on the day.
Every name and every 18th birthday message, theirs to keep.
Questions
Can I send an 18th birthday card from a group?
Yes. On tbf you create one card and share a link. Everyone signs in their own time and it arrives on the day.
When should I set up the group card?
A week before is plenty. Earlier is better if the group is large or scattered.
What if I miss the birthday?
You can still send it. A late card with twenty names on it lands better than nothing.
Somebody has a day coming up.
