I e-mailed H to ask him if he sent me the e-card. I included a link to the one I found at bluemountain and told him how sweet I thought he was for sending it. When we were both home from work tonight, he showed me the flowers he bought me. He said he hadn't sent the e-card and it made him feel guilty.
I guess the card was spam or phish. Oh well, it got me some more flowers.
