The Card Genie Pro is an optional subscription for people who send a lot of cards. You do not need it to use the site - paying per card is the normal way, and there is no subscription required.
Pro adds:
- A discount on every card you make.
- Earlier reminders so you are never caught out by an occasion.
- Scheduled sending - set a card to send itself on a future date (a birthday morning, an anniversary), so you can make it now and forget about it.
You can cancel anytime, and you manage it from your account page.
Current Pro prices are on the Pricing page, which is always the up-to-date source.
