We have many designs that are free, if sent without any premium options added. You can send a free card to up 2,000 email addresses.
When you’re browsing card designs, look for the "Free" filter on the left hand side of the page, or above the first card result. The pricing of each card is also listed once you click into its thumbnail. If the card is free to send, it will say "Starting at Free."
Any card design that is advertised as free will not have a coin cost to send, but you may need to remove Premium defaults (like envelopes or backdrops) from your Customize page once you get started.
