Yes. The sender can delete a card they've sent, and once deleted it disappears for everyone, including the person it was sent to.
To find it:
- Open You (on a phone, at the bottom of the screen) or your name at the top (on a computer), then go to Cards.
- Find the card you sent in the list of your cards, which shows both sent and received cards.
- Use Delete on that card.
If you can't see a Delete option on the card, the Cards page is the place to check, and you can send the question through Feedback (the link at the bottom of every page) for the exact steps on your version of the site.
