An e-card is an electronic greeting card sent through the Internet. People send e-cards, often featuring animation and music, to friends, family, and business associates. A person who would like to send an e-card merely has to visit a website that offers a selection of electronic greeting cards. The person chooses a card and is allowed to personalize it by writing a message.

The card can be sent to one person or several. Once an e-card is sent, the recipient opens the email and clicks on a link in order to view the electronic card. She then has the option of choosing an e-card in response to the sender's message. Sending an e-card is an environmentally friendly way to send greeting cards to people because no paper is used during the process.
