FAQ about opens and Gmail caching

I had hoped to blog about something else today, but this still seems to be a big concern for a number of people. There are a lot of questions running around, some of which we don’t have answers to, others of which we have answers based on some evidence. It’s important to remember that we’ve […]

Gmail deploys image proxy servers

This afternoon Justin Foster of LiveClicker posted to the OnlyInfluencers list asking about Gmail rewriting links. Sometime very recently (last 24-48 hours), we are seeing that Google made a change to Gmail such that all image URLs in the email content are replaced by a call to Google’s content caching service googleusercontent.com. For example, an […]

Tor cleans up their lists

Recently I got an email from Tor. Apparently they’re watching their opens and clicks and they noticed I hadn’t loaded any images recently. We notice you haven’t opened the Tor.com newsletter in a while, and that’s okay: we know you’re busy. That’s why we create our newsletter from scratch each week, to highlight the articles […]

Meaningless metrics

I’ve been having some conversations with fellow delivery folks about metrics and delivery and bad practices. Sometimes, a sender will have what appear to be good metrics, but really aren’t getting them through any good practices. They’re managing to avoid the clear indicators of bad practices (complaints, SBL listings, blocks, etc), but only because the […]

Subject lines

There has been a lot of discussion in various places recently about subject line length and how it affects email marketing. There have been multiple studies done on how the subject line affects opens and clicks. (Mailchimp, Alchemy Worx, Mailer Mailer, Adestra). The discussion has even spilled over into Ken Magill’s newsletter today. I’ve had […]

Reporting email disposition

Most regular readers know I think open and click through rates are actually proxy measurements. That is they measure things that correlate with reading and interacting with an email and can be used to estimate how much an email is wanted by the recipients. The holy grail is, of course, having ISPs report back exact […]

Forcing those opens

Most email marketers want to see their open rates go up. This particular marketer has come up with a new way to force recipients to load their mail. I’m not sure how successful this approach is going to be. I can see how this might increase open rate, as people who are interested in registering […]

What email metrics do you use?

Vertical Response talks about email metrics that are useful on a dashboard. Metrics are an ongoing challenge for all marketers. The underlying need for metrics is to evaluate how effective a particular marketing program is. Picking metrics involves understanding what the goal is for a particular program. If your goal is brand recognition then perhaps […]

Don’t take my subscribers away!

Tom Sather has a good summary of the problems with inactive email addresses and why data hygiene is critical to maintain high deliverability. These recommendations are some of the most difficult to convince people to implement. Some of my clients even show me numbers that show that a recipient that hadn’t opened or read and […]

  • AOL problems

    Lots of people are reporting ongoing (RTR:GE) messages from AOL today.  This indicates the AOL mail servers are having problems and can't accept mail. This has nothing to do with spam, filtering or malicious email. This is simply their servers aren't functioning as well as they should be and so AOL can't accept all the mail thrown at them. These types of blocks resolve themselves. 1 Comment


  • Fixing discussion lists to work with new Yahoo policy

    Al has some really good advice on how to fix discussion lists to work with the new Yahoo policy. One thing I would add is the suggestion to actually check dmarc records before assuming policy. This will not only mean you're not having to rewrite things that don't need to be rewritten, but it will also mean you won't be caught flat footed if (when?) other free mail providers start publishing p=reject.No Comments


  • Sendgrid's open letter to Gmail

    Paul Kincaid-Smith wrote an open letter to Gmail about their experiences with the Gmail FBL and how the data from Gmail helped Sendgrid find problem customers. I know a lot of folks are frustrated with Gmail not returning more than statistics, but there is a place for this type of feedback within a comprehensive compliance desk.No Comments
