Does anyone know how to advertise on yahoo mail with those banner ads?
Thank you all for the time!

Currently , Even i want to know it , i think that option is not available and so i would suggest that you can contact yahoo directly about this , their customer care is good.

Um.....
.....if you google "advertise on yahoo mail" the first listing is
"Advertising Opportunities on Yahoo Mail."

And I bet they didn't even have to submit any articles or use Xrumer to get the listing
