Gmail - charge the sender or sell the customer! (Score 1)

Don't be too quick in telling your newsletter subscribers to move to Gmail, because while Google doesn't charge the sender on the inbound, they do however sell your customer out to the highest bidder. So, if you're sending a newsletter on custom auto-parts (hoping to possibly attract your reader to your website to purchase product) don't be surprised when Gmail hijacks your customer with a highly targeted ad from one of your competitors placed just to the right or your news letter copy.

Gmail Prediction - I'll tell you something Gmail will introduce someday, paid protection! - per email paid advertisement protection so your competitors ads can't bid on your customers. And I'm sure Google will optimize the fee by basing your protection fee based on the current market price of those bidding on the keywords within your message.
