Have a client I am email marketing for. My send IP Addresses have been whitelisted by the receiving client.

EDIT: What other precautions can I make to ensure this official business email is received enterprise-wide?

there's no way to guarantee 100% delivery – Dagon Feb 23 '11 at 3:48
Why would this be voted down? How about an edit to ask "what other precautions can I take to increase delivery rate after the ip addresses have been whitelisted?" – Christopher Ickes Feb 23 '11 at 3:58
i didn't vote it it down, but some people think all email marketing as spam, there are a lot of resources on what you should do with mail headers etc, all over the web. – Dagon Feb 23 '11 at 4:06

It depends on the receiving side. You can check the pages provided by Yahoo, AOL and Hotmail to the postmasters of other email services but it usually involve following best practices and good behaviour with the receiving side along with setting up some technologies like DKIM or SPF.

Thanks. DKIM and SPF helps. Also found this link – csi Feb 24 '11 at 15:50

You also need to look at the various feedback loops like AOL's SCOMP, Hotmail's SNDS, and make sure that you deal with any abuse reports immediately. Make sure that your mail system handles bounces and unsubscribe requests correctly.

If your unsubscribe system requires anything more than replying to the mail with "unsubscribe" as the subject, or clicking on a single link, you're doing it wrong.

However, as already pointed out by Dagon, there's absolutely no way to guarantee 100% delivery.

Thanks. Do a great job of handling bounces and unsubscribes but can do a better job with email size and the amount of emails "delivered" at once. – csi Feb 24 '11 at 15:52
