    Because of web based email programs I think a plain text newsletter is the most effective. Don’t get me wrong. I love HTML emails but I have noticed a better response on just plain text email.

    I am with Thomas here, I send out primarily text based emails and avoid any problems. I find that many people actually like a no frills text email, and then a link to either see a pretty html page or to the actual product.

    Great Information Here!

    Thanks for the stats.
    We usually get better response on plain text emails.

    Interesting article. I’m pleased that my first aweber.com autoresponse didn’t get filtered to my Yahoo spam bin, but the same autoresponse from another leading autoresponder service DID go to my spam folder.

    I’m pleased to have it confirmed WHY my E-mails never seem to get through to my friends using NTL. Are they REALLY that bad?

    I thought AOL was bad. I’m always getting ‘good’ E-mails trashed.
    Many that I know have been sent, don’t even get that far.

    Ultimately that’s something you should test to see what your own subscribers prefer. We have a lot of users who send plain text-only messages as well as a lot who send text/HTML, and it’s impossible to say that one is definitively better than the other for everybody.

    Placing an HTML version of the message on your website and then including a link to that page in your message is an oft-used way of driving subscribers back to your site. If you prefer to send plain text-only messages, it’s something you may want to try out.

    I think the sorting isn’t quite correct on those stats. Not like it’s statistically significant, but e.g. yahoo.ca at 0.64% should be above rediffmail.com at 0.60%, and so on.

    There is another level of filtering taking place that might not be so obvious, but is very damaging to deliverability as I have discovered, and is indpendant of ISP’s.

    The Microsoft Outlook client filters incoming messages that it considers as spam directly to the junk box.

    The definition of spam is not configured by the user apparently, but by Microsoft through the default filters, and the filter updates it presumably gets through the "Update" utility.

    This is an insidious filtering because it is recorded as delivered bt AWeber, but is then trashed by the mail client before the User sees it. All my messages sent through AWeber are being filtered and junked in this way, so the only deliverables are the ones where the recipient does not use Outlook. I do not know whether this applies to Outlook Express – if it doesn’t it probably will sooner or later.

    I suggest that AWeber needs to approach Microsoft to whitelist AWeber sent messages either by default, and/or through the Update program that updates the filters.

    Failing to do this will mean that deliverability numbers are meaningless and much lower than indicated.

    While content filtering does affect email deliverability, it’s by no means unique to the Microsoft Outlook email client, and is a manageable challenge.

    The filtering that you refer to is not a result of you sending your email through AWeber. It’s a matter of what content appears in your messages.

    There are things you can do to get more of your email to the inbox, and they apply to Outlook as well as to major webmail clients. One of the most important ones is to have subscribers add you to their address books.

    With respect to Outlook 2007, Microsoft says:

    "You can specify a list of e-mail addresses or domains whose messages should always be treated as junk; you can also specify a list that should never be treated as junk."

    Major webmail clients such as Yahoo, Hotmail, AOL, Gmail work in much the same way.

    Providing whitelisting instructions to your subscribers (on your Thank-You page, for example) can help your messages reach the inbox.
