Cheetahmail on appending

Experian CheetahMail believes that opt-out email appending is no longer an acceptable practice, and that marketers should no longer use of this practice to acquire customer email addresses. EmailResponsibly

In my experience, appending causes major delivery problems. Of course, every time the issue comes up some marketer tells us who think it’s a bad idea that they successfully used appending and it worked and all the delivery problems are a figment.
Maybe the supporters will believe Ben and Experian / CheetahMail that appending is not a good thing to do. After all, Ben was a large proponent of the practice many years ago and Experian still sells appending services in some countries.
Sending mail without permission, which is what appending usually is, will cause delivery problems. Stick to real permission, not vague promises.

Guaranteed email delivery

Ben over at Mailchimp has a good post about his response (and his support staff’s more professional and helpful response) to inquires asking if Mailchimp can guarantee an improvement in delivery.
I sympathize with Ben, and commend his staff. I often get potential clients asking me if I can guarantee I can get their mail to the inbox or get them off a public or private blocklist. And, the answer really is no, I can’t guarantee anything. Much of delivery is solely in the hands of the actual sender. Sure, ESPs can enforce a certain standard of behaviour and they can do all the technical things right. And consultants like me can tell you how ISP spam filters work and explain how some of your choices and processes affect delivery. But none of us can guarantee inbox delivery.
Only one company has tried to guarantee inbox delivery, and they shut down earlier this year because they were non-viable and couldn’t get enough of a recipient userbase to attract customers.
For the rest of us, though, the best we can do is give senders the tools and information they need to succeed in getting mail delivered to the inbox.
