What about the email client?

what-about-the-email-client?

There are a lot of folks in the email industry that take issue with my stance that DMARC is not a viable solution to phishing. DMARC, at it’s absolute best, addresses one tiny, TINY piece of phishing. Look at this message I received today. My mail client presents this as from Quickbooks and hides the actual from email address from me. Most mail clients do…

Same MX, different filters

same-mx,-different-filters

One of the things I do for clients is look at who is really handling mail for their subscribers. Steve’s written a nifty tool that does a MX lookup for a list of domains. Then I have a SQL script that takes the raw MX lookup and categorizes not by the domain or even the MX, but by the underlying mail filter. Part of that…

Bad marketing automation, part deux

bad-marketing-automation,-part-deux

Back in April I wrote about some poor marketing automation that ended up spamming me with ‘cart abandonment’ emails when the issue was the company’s credit card processing went down. That post has now been scraped by the spammers Moosend and they keep sending me… poorly targeted automated spam. So, yes, Moosend (who are prolific and annoying spammers) are sending me spam about a blog…

Troubleshooting: the questions

troubleshooting:-the-questions

In my post earlier this week, katie asks: what do you do next when the problem statement is as non-specific as “open rates are falling”? how would you go about getting from there to that next level of marketing email from our ESP goes to bulk? That’s a great question, and will help me explain pieces I didn’t in the initial post. The observation here…

Cost of authentication

cost-of-authentication

At the end of last year, Steve wrote a post about the different types of authentication. I thought I’d build on that and write about the costs associated with each type. While I know a lot of my readers are actually on the sending side, I’m also going to talk about the costs associated with the receiving side and a little bit about the costs…

Troubleshooting delivery problems

troubleshooting-delivery-problems

Everyone has their own way of troubleshooting problems. I thought I would list out the steps I take when I’m trying to troubleshoot them. Clarify the problem. As a consultant, folks come to me asking me to help them solve their delivery problems. My first step is to get them to clarify what symptoms they’re seeing. Something happened to make them contact me, and that’s…

Happy New Year

happy-new-year

Well, it’s 2020. The start of a new year and a new decade, or not depending on what number theory you use to count decades. Personally, I think we, as pattern loving humans, just happen to love numbers that end with 0 and we’re going to consider it special whether or not it’s the actual end or start of a decade. This is the point…

Authentication

authentication

Some notes on some of the different protocols used for authentication and authentication-adjacent things in email. Some of this is oral history, and some of it may be contradicted by later or more public historical revision. SPF Associates an email with a domain that takes responsibility for it. Originally Sender Permitted From, now Sender Policy Framework. It allows a domain owner to announce which IP…

Google IP reputation bad

google-ip-reputation-bad

This morning hundreds of delivery folks logged into their Google Postmaster Tools account to see their IP reputation was bad. Even one of my client’s that is using a major ESP shared pools is seeing bad IP reputation on December 10, 2019. The good news is this doesn’t seem to be affecting delivery. Most folks are reporting no delivery issues at Gmail and no change…

It’s not marketing… it’s harassment

it’s-not-marketing…-it’s-harassment

Many years ago, we bought a VMWare license to manage the various virtual machines running our business infrastructure. As part of our move to Dublin, we decommissioned our cabinet and moved all of services into various bits of the cloud. This meant that when our VMWare support contract came up for renewal we declined the renewal. Despite no longer being customers and unsubscribing from email,…

It’s the email time of year…

it’s-the-email-time-of-year…

I’m basically waiting for the various ESPs to announce Just How Much Mail they’ve sent over the last 4 days. Early information from one ESP shows a hefty percentage over the amount they sent last year, and that amount had many, many, many zeros in it. In terms of best practices and ongoing advice: you can never put too many lights on a Christmas tree.

There’s something about bounces

there’s-something-about-bounces

I’ve shared a version of this image repeatedly. I think it was only my Facebook friends that got the stick figure screaming in frustration, though. The reality is bounce handling is one of the most frustrating pieces of email delivery. Not only that, many people in the email space treat it as a simple process. It’s really not as simple as we’d like it to…

Phishing evolves beyond DMARC

phishing-evolves-beyond-dmarc

The phishing attack against Sendgrid is still going on. Most of the mail and the websites are being hosted on Linode. I’ve still not gotten to see what one of the sites looks like, as Linode is getting the sites down before I click on the links. Everyone here is doing the Right Things(tm) in order to address the problem. Sendgrid has a p=reject message…

Myths about spamtraps

myths-about-spamtraps

The nice folks at Kickbox asked me what I thought the biggest myths about spamtraps were. I said: I think the biggest misconception is that spamtraps are the reason for delivery failures, whether blocking or spamfoldering. When the article came out, I was highly amused to see that John from Campaign Monitor said the same thing in his first sentence, too. A common misconception is that spamtraps are…

ESP being phished is a Black Friday cataclysm

esp-being-phished-is-a-black-friday-cataclysm

There is currently a phishing attack against a major ESP. The mail came through what I presume was a compromised account hosted at one of the providers. It’s just as possible this was a domain set up for the sole purpose of phishing, though. The underlying attack is pretty good. They took the ESP compliance notification email and changed a couple of the links to…
