There are many free ones MOST of which contain, at the least, tracking cookies. Tne one that I have used for years without any problems is Hallmark, the regular card people. They have popups but are a fairly trustworthy company. This link is for the Free E-cards. You MAY have to join the website, I don't remember because I have already been a free member for more years than I wish to say. LOL.
Can you give me a couple of links for free ecard websites please.
I'm not too sure what is safe to send.
What i'm looking for, if possible is animated musical Christmas cards, nice, unusual, whatever is available i'll be happy with.
