This might work, but the people getting the message need that value communicated. Cute dinosaur emails do not say 'I'm throwing money around'. The site would need a complete redo.
On the other hand the cute dinosaurs are very appealing right now. And this service is likely really cheap to run, and collects the names and emails of people, new parents, who will be purchasing lot of stuff right now... That's valuable and I think that's the revenue stream I'd go after.
