My new partner has an email list with over 1 Million email addresses for targeted traffic (no spam... only genuine subscribers from his last startup )But now I have a problem.. how can I sent an email to all those email addresses ?I can't use my ISP SMTP mailer, they will block me immediately for bulk mailing.I thought of a way to send emails slowly . Like dividing them in sets of few thousands and sending to each set daily .Will it be fine solution ?
How to send thousands of promotional emails to opt in addresses without being blocked

I agree with the other answers, opt in is opt in for a specific purpose.  You need to be very careful about what and how you send...it can be a very expensive mistake if you don't follow all CANN-SPAM regs.But to answer your email question, there are hosted STMP relays that you can purchase access to such as SocketLabs and SMTP.com.  I prefer these to a MailChimp if I'm going to be doing something proprietary and repetitively.  I've had great success re-selling email marketing via Interspire's Email marketer combined with either SocketLabs or my own Co-Lo'ed server doing the routing.Throttling (which is what you describe) is something my company uses to ensure the big three (AOL, Gmail, MSN/Hotmail) don't peg you as a spammer right off the bat...it could be 40% of your list, believe it or not.  I would refrain from using it to trick the server hosts, as they'll eventually catch on and the result usually isn't very much fun.
