Usually when you send an ecard, the company providing it can collect not only your email address, but that of the person you are sending to as well.
Sometimes you even pay to send an ecard. Not here. The ecards are free. There is no registration required, and you send it yourself by email using the form
I provide. The only way I get an email address is if your recipient or you
opt in to my email list.
As I come up with new email cards they will be announced in that opt-in list.
