An E-Card is a digital greeting card that can be sent via email or shared on social media. These cards often feature colorful designs, animations, and personalized messages, making them a popular choice for special occasions like birthdays, holidays, and anniversaries. E-Cards can be created using various online platforms, allowing users to customize their cards with images, text, and music. Unlike traditional paper cards, E-Cards are environmentally friendly and can be delivered instantly, making them convenient for last-minute greetings. Many websites offer free E-Cards, while others provide premium options for a fee. Popular E-Card services include American Greetings and Blue Mountain.
