Podia has scraped the Word to the Wise blog and I’m currently receiving an ongoing drip campaign from them absolutely begging me to mention them in my blog post on cold emails. I get maybe a dozen of this style of email a week. It’s pretty annoying but whatever. I delete them, blog about them or, very occasionally, share them with some folks who might have a big bigger of a stick to...
Yesterday I learned that some ESPs don’t support the reply to: address. I asked around to discover which ESPs did. Here’s what I learned.

As I continue to think about how people troubleshoot email delivery I keep finding other things to talk about. Today we’re going to talk about the question most folks start with when troubleshooting delivery. “Did ISP change something?” At least once a week I check some delivery or email fora and some form of the question is sitting there. “Did X change something? We...
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 that by default. It is possible to...
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 script classifies domains hosted by Google apps as a separate filter...
In my previous career I was a molecular biologist. Much of my work was done on bacteria but after I left grad school, I ended up working in a developmental biology lab. Bacteria were (mostly) simple: just about every trait was controlled by a single gene. We could study what that gene did by removing it from the bacteria or adding it to a well characterised bacteria. When I moved to developmental...
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...
There’s a lot of my education in the sciences that focused on how to get a statistically accurate sample. There’s a lot of math involved to pick the right sample size. Then there’s an equal amount of math involved to figure out the right statistical tests to analyse the data. One of the lessons of grad school was: the university has statistics experts, use them when designing...
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 is: “open rates are falling...
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 for intermediaries such as CRM systems or...
