IP Address & Email Inbox Deliverability?

Hi,

I have not sent out any spam through my IP address but it seems like customer emails that I send out still get delivered to the customer's spam/junk folder; especially for yahoo/hotmail email addresses.

My IP address is not blacklisted and I've done everything I possibly could to increase "inbox" delivery. I've set up a SPF record, DKIM, Domain Keys, PTR record, joined Bing's SNDS, registered IP with EmailReg.org, registered IP with dnswl.org, etc.

I've done all the above and still yahoo/hotmail/msn emails get delivered to their "spam/junk" folder.

My website has been "live" for about a year now; so I wonder if the reason for this is due to not having a good "email reputation" yet for my IP address?

Does anyone have any other tips/suggestions I can do to get emails sent to yahoo/hotmail/msn delivered to the customer's inbox?

My last resort was to maybe try changing my IP address, but does changing your website IP address cause the same issues to occur again because now the new IP address has to build "email reputation" again?

Thank you!

also forgot to mention it might not be just your IP - it might be "the neighborhood".

have you checked your IP in all the usual places? (SANS ISC, project honeypot, spamhaus, ironport, etc)

Hotmail and Yahoo have very agressive filtering and you still get false positives even if you do everything right. Not to mention the fact that they have the sort of users who click the "spam" button as the easy way to move a newsletter out of the inbox.

do you have reverse dns configured?

A little more detail might be helpful like:

is your server a shared hosting y/n
DNS passes online health checks that test email portions?
Is the IP address on ANY blacklists? see mxtoolbox to check
Is the email server in an IP block marked as 'portable'? (for end user devices)

Yes, I have reverse dns also configured.

No, it's on a dedicated server using a static IP address.
Yes, DNS passes all online checks.
No, it is not listed on any blacklists; I checked on mxtoolbox.

How can I check if the IP block to see if its marked as 'portable'?

I'm looking into signing up with ReturnPath, it looks like if I were to get certified with them I would have a higher level of inbox delivery. I guess its worth a try.
