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?
