I’ve been doing a lot of my question answering over on the Email Geeks slack and have decided to bring some of the answers over here. Today’s question: My ESP provides a dashboard of spam complaints. How should I be looking at the data? Are some complaints more important than others? The spam complaint dashboard is a record of the feed back loop messages (FBLs) that an ESP has...
Just a very, very short post with links to the Yahoo and Google requirements FAQs. Given I can’t ever remember them I’m guessing lots of y’all can’t either.

Another day, another ESP telling a client to publish a SPF include for the wrong domain. It shouldn’t annoy me, really. It’s mostly harmless and it’s just an extra DNS look up for most companies. Heck, we followed Mailchimp’s advice and added their include to our bare root domain and it’s not really a huge deal for companies with only a couple SaaS providers. Still...
(Copied and lightly edited from a Facebook post) It occurred to me as I was commenting elsewhere that there is a lot of confusion about domains / subdomains and where they’re used in emails.I get confused when people talk about ‘domain reputation’ because I have at least 4 distinct places where domains show up in an email that heavily influence delivery. But a lot of other folks...
A few weeks ago I was on an industry call. We were discussing some changes coming down the pike at the ISPs and filter providers. These changes are going to cause some headache at ESPs and other places that do email but don’t provide mailboxes. During the call I ended up explaining why what the ISPs were doing made sense and how it fit in with their mission and customer needs. At one point...
It’s been a light blogging month. We’ve been dancing around getting the final plans, financing, and contractors set up for the work we’re doing on the Dublin house and then heading off for our first actual vacation in almost 5 years. But, I wrote half of this answering a question on mailop, so I may as well polish and publish. What is FCrDNS FCrDNS stands for Full Circle reverse...
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...
A couple folks have asked me recently about MX records that they don’t understand. These records consist of a single . or they contain localhost or they are 127.0.0.1. In all cases, the domain owners use these records to signal that the domains don’t accept email. What do these records look like? Why do domains do this? In all cases it’s because the domain owners want to signal...
A question came up on the email geeks slack channel about empty from addresses. I asked if they meant the 5321 or 5322 from address which prompted a question about if you could even have a null 5321 from. Yes, you can and it’s commonly used for some types of email. 5321.from is the bounce address, and the domain used in SPF authentication. Null addresses, literally <>, are used for email...
