Filter complexity

During the Q&A last week, I mentioned an example of a type of filter trying to demonstrate how complex the filters are. There was some confusion about what I was saying, so I thought I’d write a blog post explaining this. Background This story came from another deliverability person, let’s call her ESPer. One of […]

Thanks for the great session

I had a great time answering questions at the 2015 All About eMail Virtual Conference & Expo today. Thanks so much to everyone who participated and asked questions. They were great and I’m sorry we didn’t have more time. I did get some questions on twitter (@wise_laura) afterwards. One was about an example I gave to […]

SPF debugging

Someone mentioned on a mailing list that mail “from” was being filed in the gmail spam folder, with the warning “Our systems couldn’t verify that this message was really sent by“. That warning means that Gmail thinks it may be phishing mail. Given they’re a well-known financial services organization, I’m sure there is a lot […]

July 2015: The Month in Email

Once again, we reviewed some of the ways brands are trying (or might try) to improve engagement with customers. LinkedIn, who frequently top lists of unwanted-but-legitimate email, announced that they’ll be sending less mail. Josh wrote about giving subscribers options for both the type and frequency of messages, and about setting expectations for new subscribers. […]

Thoughts on Gmail filtering

Gmail has some extremely complex filters. They’re machine learning based and measure hundreds of things about incoming mail. The filters are continually adjusting to changes and updating how they treat specific mail. One consequence of continually adjusting machine learning filters is that filtering is not static. What passes to the inbox now, may not pass […]

Mythbusting deliverability and engagement

Yesterday I published an article talking about an engagement webinar hosted by the EEC and DMA. I made a couple predictions about what would be said. ISPs do monitor engagement, even if they do it differently than senders thought. Engagement is important for inbox delivery at some ISPs. Different ISPs have different ways of making […]


Email predictions for 2015

Welcome to a whole new year. It seems the changing of the year brings out people predicting what they think will happen in the coming year. It’s something I’ve indulged in a couple times over my years of blogging, but email is a generally stable technology and it’s kind of boring to predict a new […]

  • Lost in the mists of time

    Over on the Farsight Security blog Joe St. Sauver talks about some of the early days of online abuse, on usenet. Laura and I were on the periphery of early usenet abuse, mostly as users, but Usenet (and IRC) around then were the places we both started with email abuse.No Comments

  • Ongoing Yahoo delays

    I've been hearing from folks over the last few days that they're seeing an uptick in deferrals from Yahoo! The deferrals are not uniform. ESPs report they're seeing some, but not all, customers affected. Other ESPs aren't seeing any changes. It's not just you. But it would be very worthwhile to dig into engagement and other stats. It's possible this is a new normal at Yahoo! and they're tightening filters to catch mail that doesn't fit their standards but was previously difficult to filter.No Comments
