Ladies and gents, let me introduce you to a classy site for sending invitations and greeting cards over the Internet. Of course, nothing beats sending mail the old fashioned way (by snail!), but this is a lovely alternative when you absolutely must correspond technologically.
Just look at these lovely invitation designs:
I needed to put together an email invitation recently and wanted something classier than the old Evite sites that I'm used to using. Paperless Post has been a breeze to use and it is dutifully keeping track of all the accepts and regrets for me like a loyal personal assistant. You have to have "stamps" to send the cards, which you can earn for free or purchase at extremely low rates. Plus, you get 25 stamps just for signing up. Hooray for pretty technology!
