You can send an unlimited number of eCards per day; however, there is a limit to the number of recipients you can include in each eCard. When you select to send your eCard to a "Group" of contacts you have created in your address book, you can send your eCard to up to 2,500 recipients with a single click.
When you manually enter/paste/select addresses, either from a list or your address book, you can send your eCard to up to 250 recipients. If you have a bigger list then simply copy the eCard you just sent and send the copy to the next 250 people on your list. You can do this as many times as you like until all your recipients' eCards have been sent. (We make it easy by giving you the option to "copy card" after each one is sent.)
