Data Mining Software & Mass Emailer (without the recipients knowing)

Hey Guys,

I'm needing to get a list of contacts (email addresses) for as many Tuxedo shops as I can find. Is there an automated way (tool) for this? Once I get this list, I'll want to send out a mass email to all of them but I want each of them thinking I've only sent the email to them and no one else. (Initially I was thinking MailChimp but I think there's a note somewhere in the email that says it was sent as a subscription emailer or something)

Thanks for any tips.
