Changing my homepage from what I wanted it to be is not going to make me try your product. Quite the opposite.
Trying to installing Google Chrome and Toolbar when I update something else will not encourage me to use it.
I never buy anything from an unsolicited email. I do not buy anything from cold callers on principle. I encourage everyone reading to do the same and perhaps this whole obnoxious industry will wither and die.
Sending me junk mail will not achieve anything positive. You are just wasting trees. Sending me a pension plan for the over-50s when I was only 43 ensures that I will never, ever deal with that company (Sun Life), ever!
Junk mail with prepaid envelopes does offer some amusement. If you send them back the company has to pay, I believe. Stuff your prepaid envelope with any other junk mail you got. I am sure the man trying to sell you overpriced aluminium windows needs a pension plan.
