Poor delivery can't be fixed with technical perfection

There are a number of different things delivery experts can do help senders improve their own delivery. Yes, I said it: senders are responsible for their delivery. ESPs, delivery consultants and deliverability experts can’t fix delivery for senders, they can only advise.
In my own work with clients, I usually start with making sure all the technical issues are correct. As almost all spam filtering is score based, and the minor scores given to things like broken authentication and header issues and formatting issues can make the difference between an email that lands in the inbox and one that doesn’t get delivered.
I don’t think I’m alone in this approach, as many of my clients come to me for help with their technical settings. In some cases, though, fixing the technical problems doesn’t fix the delivery issues. No matter how much my clients tweak their settings and attempt to avoid spamfilters by avoiding FREE!! in the subject line, or changing the background, they still can’t get mail in the inbox.
Why not? Because they’re sending mail that the recipients don’t really want, for whatever reason. There are so many ways a sender can collect an email address without actually collecting consent to send mail to that recipient. Many of the “list building” strategies mentioned by a number of experts involve getting a fig leaf of permission from recipients without actually having the recipient agree to receive mail.
Is there really any difference in permission between purchasing a list of “qualified leads” and automatically adding anyone who makes a purchase at a website to marketing lists? From the recipient’s perspective they’re still getting mail they don’t want, and all the technical perfection in the world can’t overcome the negative reputation associated with spamming.
The secret to inbox delivery: don’t send mail that looks like spam. That includes not sending mail to people who have not expressly consented to receive mail.

Buying Lists

One of my email addresses at a client got spammed today offering to sell me appending services. I was going to post the email here and point out all of the problems in how he was advertising it, including violating CAN SPAM.
As I often do, I plugged his phone number into google, only to discover that my blog post from March about this spammer was the 2nd hit for that number. Well, go me.
I can report nothing has changed. He’s still violating CAN SPAM. He’s still claiming I have no right to post, share, spindle, mutilate or fold his spam. Well, in the interest in something, I thought I’d share the whole post this time. Just to warn folks from attempting to purchase services from appendleads.com (nice website, by the way).

Appendleads is not unusual

I called out David Williams from appendleads.com yesterday for his spam. Sure he’s a spammer, his database is full of garbage information and his email violates CAN SPAM but he’s not that unusual in the realm of list sellers. He is very typical of the people I see offering lists for sale.
List sellers are the internet version of used car salesmen. Everyone knows they are slimy sales guys who will do anything to close the sale. They don’t have a real web presence, just visit appendleads.com and see what I mean.
And yet, people still buy lists from them! I have no doubt that my spammer friend has a nice little business selling email addresses. He sends out spam, he gets a few responses, makes a tidy profit and then sends out another spam, hooks a few more people and makes more money.
OK, so not all list sellers are like appendleads. Some of them go so far to build a website. But at the core they’re the same. They are selling data that isn’t clean, it’s not opt-in, it’s not been verified.
This is why so many of us harp on not buying lists. The sales guys talk a great game, but they aren’t selling what purchasers think they’re getting. They also don’t care. They have no incentive to clean up their data. They have no incentive to accurately represent what they’re selling. All of the risk is on the person that sends the email. Once they have their money, the buyer is on their own.
Can you ever successfully purchase a list? I’m sure some senders have. But that experience is closer to winning more than a thousand dollars in the lottery than an actual good business decision.

The view from a blacklist operator

We run top-level DNS servers for several blacklists including the CBL, the blacklist of infected machines that the SpamHaus XBL is based on. We don’t run the CBL blacklist itself (so we aren’t the right people to contact about a CBL listing) we just run some of the DNS servers – but that means that we do get to see how many different ways people mess up their spam filter configurations.
This is what a valid CBL query looks like:
