As part of our ongoing effort to get your emails delivered, we recently upgraded our authentication system to include support for DomainKeys Identified Mail (DKIM). This additional authentication technique is similar to the already supported DomainKeys approach, but is now an IETF standard and is already supported by ISP’s such as Yahoo! and Gmail.

While there are lots of benefits to authenticating your from address, one of the most important is that it’s a requirement for the Yahoo! feedback loop. A feedback loop means that Yahoo! automatically inform Campaign Monitor if any of your subscribers mark any of your emails as spam. This actually has a number of advantages of its own:

  1. Keep your content relevant

    We report on all complaints from ISP’s that support spam complaints (such as Hotmail, AOL and a bunch of others) and collate that into a single report for each campaign. Spam complaints are a fantastic way to gauge the relevance of your campaign. If complaints are low, clearly your subscribers are interested in what you’re sending. If you notice a sudden spike in complaints, it’s more than likely that your content doesn’t match the expectations you set when getting their permission in the first place.


    Using our compare campaigns report (pictured above), you can easily chart the complaint rate for any campaigns you’ve sent, which makes spotting any dramatic increase in complaints a breeze.

  2. Keep your list clean

    Whenever any of your subscribers at Yahoo! mark your email as spam (instead of unsubscribing) we’ll instantly remove that subscriber from your list.

Here’s the best part, you don’t have a to lift a finger to support it. If you’ve already set up DomainKeys for yourself or a client, we’ll automatically start signing all your outgoing emails with a DKIM signature too. We also automatically register any of your authenticated domains with the Yahoo! feedback loop so you can keep an eye on your relevance immediately.

If you haven’t already enabled authentication in your account, here’s a walkthrough of the process, as well as a step-by-step guide for adding authentication records to your DNS.
