1001 Postcards has a huge selection of cards, a few animations, and some unusual topics like you can send a weather forecast (Wish you were here. Get it?). Easy to navigate. Creativity is rampant on this site. Relies heavily on public YouTube animations.

Regards - has a nice selection of pictures and has some multimedia cards. The site relies on Flash - just saying.

RiverSongs - has a large selection of completely free ecards including animation and music although I couldn't get the site to work the last time I tried???.

Ladydi Postcards - very HUGE list of links to e-cards. Their listings indicate if a site has music and/or animation. Hard to find anything useful due to the broken links and junk.

JustWink lets you add your own picture and signature (you actually sign the card with by using your mouse) to their non-animated cards but you have to get a free account.

CardSpot has e-cards. Nice selection of pictures and pre-authored sentiment - good art - no music. Couldn't get it to work last time I tried???

Some Ecards - requires a Chrome plugin but the cards are very creative and snarky.

Disney Greetings by Pansoph Post has nice photos of DisneyWorld.

Blue Mountain $$$ - pretty good but you have to pay for a subscription.

American Greetings - $$$ subscription only

Free Postcards - a handful of links to ecard sites with short descriptions

10 Ecard Sites Most of these sites either require that sign up for an account or that you download a plugin for your browser - neither is a good idea.
