Electronic cards, or ecards, allow you to send virtual birthday cards to anyone with an email address for free. Most of these cards can be personalized in some way, and some include music or animation as an added feature.
Ecards are an inexpensive, often free, alternative to sending paper birthday cards. The electronic greeting cards are available in several different formats, including those that feature music, animation and the ability to include a photograph of the recipient (or any photo) in the card's design.
American Greetings, one of the largest retailers of traditional paper birthday cards, offers free electronic birthday cards on its website for a limited time period. They offer a paid service that gives subscribers unlimited access to all of their ecards and lets them print at home cards for a monthly fee. As of May 2015, the monthly fee is $3.99. There is a free seven-day trial period in which users can send as many free ecards as they like. If the service is cancelled before the end of the trial period, there is no charge for the cards.
For free printable birthday cards, sites such as GreetingsIsland.com allow users to customize and print birthday and other greeting cards for free. Technically, these cards aren't free, because the cost of paper, ink and a stamped envelope (to mail to the card) must be taken into consideration.
