    So backstory first; a client gives me a 100,000 person list he got from people subscribing to the site. I plug it in to constantcontact, they noticed a lot of bad e-mails, do their best to clean it up. They worry it's full of people who will mark it full of spam when we do campaigns.

    Well we send out the first campaign, ConstantContact stopped it at 10,000 e-mails cause 45 reported it as spam and 500 bounces, but they got great results from it.

    SO now I need to take the list, clean it up to get rid of the bad e-mails...
    Any software that removes bad e-mails? any software that sends an e-mail to people that wants to opt-out of the e-mail list?

    Thanks in advanced

    Frankly, there is no way to clean such a database.

    Your best bet would be to send out a new introductory email from your own servers asking people to re-optin and only use the new sanitised database.

    Set the email sender onto a temporary IP address that you can dump once the mailout has finished - as it will almost certainly be blacklisted as a spammer.

    Then reimport the new database and use that instead.

    Typically, an email database will churn about 20% of its userbase per year for active mailing lists anyway as people change email addresses etc.

    Now, the big question is when did the list owner last actually send out emails ?

    I tend to consider emails from a company I haven't dealt with for a year+ as spam as I have probably forgotten that I dealt with them originally.

    If they havent used the database before then frankly - its worthless.

    Best guess, if they have managed to capture the date the email address signed up - then go back a maximum of 3 months.

    Any older and you risk being blocked as a spammer.

    actually there is. You can use PHPList to import the emails, and set it to automatically send a confirmation email to each one

    that will clean out the undeliverables, and make sure people opt in

    PHPlist seems like a good idea, except I don't have the bandwidth or backend to send out all those e-mails on the client's servers..

    Is there a service anybody could recommend that allows me to upload 20k to 100k e-mail list and have them send each e-mail an opt-in comfrimation so I can get a cleaner list?

    Thanks so much everybody here

    constant contact allows that I believe, but it will cost more with a list of that size
