Email Marketing Software

My email list is very large and would take forever to remove people who have requested to be removed. what can I do?

I’d like something that anyone can subscribe or unsubscribe, all members can post but all post are moderated, and messages can be distributed in a digest.

I run a website and collect email addresses from different websites and forums in order to do marketing of my products. So in other words, i maintain a huge email list of my own.

I am looking for a tool or a software that can maintain email list for me so that i can send email to all the emails at once rather than using free emails for this purpose and send limited number of email per day.

Some tool that will sort out duplicate addresses and extract email from other email applications as well.

your help will be highly appreciated.

my list is over 16,000.. i want to be able to sent 2 mass email out a month.. so thats about 32,000 emails a month.. as cheap as possible.. ive been looking for like a week lol no luck.. thanks in advance

i have a mailing list and my website wont import them as they are not seperated by commas and there is way too many to do it manually, wondered if anyone knew any software that could extract the email address and save it again with commas in between?
