Email Text Ads

Hello Everybody,

I'd like to hear some opinions.

Let me take http://contactify.com for example. It is a contact form service.

Let us imagine that it starts selling Text link ads at the bottom of every email being sent.

What would be the possible price that advertisers would agree to pay ?

Like $XX/mail etc..

 

i think thats depends upon how much users you have and how much mails daily sending...
