We designed and built an ecard creator for charity Clic Sargent, finishing it in October 2010. See it here.
We were looking into the stats for it today, and have discovered that it has been extremely well received. It has been used by 1212 users, to send just over 74,000 e-cards. This has induced donations to the charity which have so far covered approximately half the build budget, in only 3 or so months!
This is only set to build as the word spreads.
We designed and built the e-card creator to make it easy and fun to create cards, with the card building itself live on screen as the user adds content. It is possible to preview the card, easily add recipients, or even multiple recipients from a spreadsheet meaning it becomes an ideal tool for corporate uses such as Christmas cards.
We worked hard to make the system easy to use, and it is very satisfying to see that this has had a direct impact on the uptake, and the resulting return on investment for the client.
