Tell me about your business model

I posted Friday about how most deliverability folks roll their eyes when a sender starts talking about their business model. The irony is that one of the first things I do with a client is ask them to tell me about their business model and how email fits into their business plan. Once I know […]

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 […]

Deliverability at Yahoo

We have multiple measures of deliverability. Ones that we don’t even let in the door, and then we have ones that customers indicated that they don’t want to be delivered.  – Jeff Bonforte, Senior VP Communications, Yahoo Mail Read a little more about Yahoo and spam over at Tech Insider, or listen to the podcast at […]

IPv6 and authentication

I just saw a post over on the mailop mailing list where someone had been bitten by some of the IPv6 email issues I discussed a couple of months ago. They have dual-stack smarthosts – meaning that their smarthosts have both IPv4 and IPv6 addresses, and will choose one or the other to send mail over. […]

Outrunning the Bear

You’ve started to notice that your campaigns aren’t working as well as they used to. Your metrics suggest fewer people are clicking through, perhaps because more of your mail is ending up in junk folders. Maybe your outbound queues are bigger than they used to be. You’ve not changed anything – you’re doing what’s worked […]

The holiday mailing season

We’re half way through September and it seems way too early to start thinking about the holidays. But for marketers, even email marketers, planning should be starting now. This planning shouldn’t just be about content and targeting and segmentation, but should also cover deliverability. Most retailers use email marketing to drive traffic to their websites […]


Reputation is about behavior

Reputation is calculated based on actions. Send mail people want and like and interact with and get a good reputation. Send mail people don’t want and don’t like and don’t interact with and get a bad reputation.   Reputation is not … about who the sender is. … about legitimacy. … about speech. … about message. […]

Deliverability strategy to reach the inbox

I wrote a piece for the Only Influencers special Holiday Preparations edition about deliverability and the holiday email rush. One thing I like about the chance to write for other publications is the process often leads me down thought pathways and generate some new ideas. One thing this post helped crystalize in my mind is […]

Continuous Testing

HubSpot recently posted an blog article comparing which was better for engagement, plain text emails or HTML emails. In a survey they sent out in 2014, 64% of the responses said they preferred the HTML and image-based emails. It seems pretty straight forward, recipients say they want HTML emails over text based emails but through […]

  • 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
