    Why is your email not being delivered?

    What you were doing before to get you email delivered probably worked, well those days are over and what you did in the past will probably make it worse today. We both face a real challenge getting out email into the inbox. This is especially true for larger ISPs like Hotmail, AOL and Yahoo.

    Many other factors can drag down the good reputation of your email IP address, increasing the chances of your email going to the spam folder (or being blocked outright).

    You have got to learn all you can about email reputation and permission. If you don’t, you will find yourself trapped in a deliverability disaster that you can’t easily fix!
    Many corporate networks run basic spam filters and throttles at the network edge, because if they can reject spam there, it frees up their server load and saves bandwidth, processing and storage.

    Always remember that ISPs have to buy Internet backbone access from upstream ISPs and that costs money. At the very core spam filters are about money. Your email is filtered not to reduce spam at the inbox, but to save ISPs and corporations money.


    It is only a matter of time, email authentication will become more important and when it is feasible ISPs will stop delivering email if you do not have authentication in place. In fact, it is a known fact and Yahoo has admitted that with out DomainKeys or DKIM in place you WILL face additional filtering.
    If you are not already authenticating with a SPF, Domain Keys, Sender ID and DKIM, now is the time. If you start now, you can be in good standing with the major ISPs by the next holiday season.


    Whereas Microsoft demands Sender ID, many others advocate a combination of SPF, DomainKeys and DKIM.
    You should have the proper authentication records in place to give the ISPs a fighting chance to identify senders and use reputation data to make delivery decisions. However, an incorrect record can do much more damage than not having one. Consider that authentication identifies where the message is coming from. When you fail the authentication check, you've just told the ISP, "This email didn't come from me. So don't deliver it."

    Awesome post!

    question...

    one of the ESPs we use to inbox YAHOO only uses SPF and we had been seen decent inbox rates for a while but lately it has been going down.

    How important is it for YAHOO to have more than this ( Domain Keys, etc )


    gracias and congrats on your coronation!

    use DKIM too

    I'd really like to get a few other guys like SG, Roundy, DG or maybe crackp0t to chime in here as well but the way I see it is using DKIM is one more way for you to identify yourself as a legetinate sender to Yahoo recipients. If you're using an ESP I'm going to guess that they're WL'd or at least they should be. As such there's a certain amount of reputation there and if you can enhance it, why not? The following is an excerp from the Yahoo postmaster's suggestions on delivering inito Yahoo more effectively:
    If they're telling you to use it, I say use it. We do. Also, and I'm hoping that your ESP has done this for you or you did, make damn sure you register your domain/IPs for their FBL. Another quote from the postmaster:

    I noticed big differences after doing this so I know it all makes a difference, and when used in combination you stand a better chance of delivery success. But even with all of this, Yahoo likes to change shit up regularly so expect fluxuations no matter what you do. Also, be preparred for a big change as they roll over to their new platform with increased security (insert: changes in their algorithm) which will fuck everything up!

    on a side note: it looks like someone started playing with forum font sizes, no?

    y muchas gracias por su comentario sobre mi coronacion mi amigo
