A client asked me earlier this week what SLAs ISPs provided for email delivery. The short answer is that there isn’t a SLA and that the only guarantee is that the email will get there when it gets there. But as I was mentioning this to Steve, he pointed out that there was a recent […]
There is a lot of contention between ISPs and senders at the best of times. As we move into the holiday season, retailers are increasing their email marketing, sometimes quite significantly. This causes more delivery issues as recipients and MTAs react to the increased volume. At many non retail companies, however, the pace of work […]
Christopher Penn at What Counts did some testing to see what delivery to Facebook.com addresses looks like. It looks pretty grim.
There’s a great post over on CircleID from John Levine and his experience with a marketer sending mail to a spam trap. Apparently, some time back in 2002 someone opted in an address that didn’t belong to them to a marketing database. It may have been a hard to read scribble that was misread when […]
I’ve been thinking lately that sometimes that what works for marketing doesn’t always work for delivery. For instance in many areas of marketing repetition is key. Repeat a slogan and forge an association between the slogan and the product in the mind of the consumer. More repetition is better. Marketers can even go so far […]
I often get clients and potential clients asking me to tell them what the absolute best ESP is. “You’re an expert in the field, which ESP will give me the best inbox delivery?” The thing is, there isn’t an answer to that question. ESPs have expertise in sending large amounts of mail. All have staff […]
It’s a problem anyone who has done any delivery work has faced. There’s a client who is having blocklist problems or ISP delivery problems and they won’t pay any attention to what you say. They insist that you talk to the blocklist or the ISP or hand over contacts directly so they can “dialog with” […]
In zombie email: part 1 I talked about how email addresses were tightly tied to internet access in the very early years of the internet. We didn’t have to worry about zombie email addresses because when an account was shut down, or ignored for a long time then mail would start bouncing and a sender […]
Our tomcat, Grover, wants to go outside. He wants to go out the side door, so he’s been sitting in front of it, looking at me, then staring at the door. He’s been doing this for about half an hour, intermixed with occasional sad yowling. The back door is open, and he can get from […]
A spam filter looks at many things when it’s deciding whether or not to deliver a message to the recipients inbox, usually divided into two broad categories – the behaviour of the sender and the content of the message. When we talk about sender behaviour we’ll often dive headfirst into the technical details of how […]
