Insight into Gmail filtering

Last week I posted a link to an article discussing how Gmail builds defenses to protect their users from malicious mail. One of the things I found very interesting in that article was the discussion about how Gmail deploys many changes at once, to prevent people from figuring out what the change was. Let’s take a […]

Don’t mess with my email

One thing we tell clients is that people consider their mailbox a very personal space. They’re offended when people invade that personal space without permission, sometimes to an extent that doesn’t seem proportional to the scale of the offense. And we advise senders who have been invited into the inbox to treat it with respect. […]

Things you need to read: 2/5/16

Ask the Expert: How Can Email Marketers Stay Out of Gmail Jail and in the Inbox? The expert in question is an old friend of mine, Andrew Barrett. I met Andrew online in the late 90s, and we worked together (briefly) at MAPS. He was out of email for a while, but I’m pleased he came […]

What do you think about these hot button issues?

It’s been one of those weeks where blogging is a challenge. Not because I don’t have much to say, but because I don’t have much constructive to say. Rants can be entertaining, even to write. But they’re not very helpful in terms of what do we need to change and how do we move forward. […]

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” intuit.com was being filed in the gmail spam folder, with the warning “Our systems couldn’t verify that this message was really sent by intuit.com“. 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. […]

Google Postmaster Tools

Earlier this month Google announced a new set of tools for senders at their Postmaster Tools site. To get into the site you need to login to Google, but they also have a handy support page that doesn’t require a login for folks who want to see what the page is about. We did register, but […]

  • HE.net DNS problems

    Hurricane Electric had a significant outage of their authoritative DNS servers this morning, causing them to return valid responses with no results for all(?) queries. This will have caused delivery problems for any mail going to domains using HE.net DNS - which will include some of their colocation customers, as well as users of their free services - but also will have caused reverse DNS to fail for most servers hosted by Hurricane Electric worldwide, so if any of your mail is being sent from HE hosted machines you may have seen problems. (We're HE customers so we noticed. Still happy with them as a vendor.)No Comments


  • 65.0.0.0/8 DNS issues

    If you're sending email from any address beginning with a 65 - in 65.0.0.0/8 - it's possible you'll see some delivery problems. Something appears to be broken with dnssec signatures for the reverse DNS zone, leading queries for reverse DNS to fail for anyone using a dnssec aware DNS resolver (which is almost everyone).1 Comment


  • Our green bar certificate is going away

    Later today we'll be switching from an Extended Validation ("green bar") SSL certificate to a Domain Validation certificate. This isn't exactly a planned change but I'm waiting for responses from Comodo before I go into it too much. I'll share some more details next week.3 Comments
