Purchased Lists and ESPs

After some thought, I’ve decided to remove a few ESPs from this list based on personal experience with them allowing customers to send to purchased lists. If your company has disappeared and you want to come back, you’ll need to actually stop the spam coming from your network. Every company that’s been removed has received a complaint from me specifically mentioning the address was purchased and allowed that same customer to continue spamming the same address. Deal with your spam and we can talk about reinstatement. 

One thing almost every ESP delivery person has dealt with, at one time or another, is a customer complaining about being unable to send to a purchased list. Inevitably, the customer will say “But other-ESP lets us send to purchased lists, why won’t you?” I’ve heard this over and over from many different colleagues.
Of course, the customer is almost always leaving other-ESP because of poor delivery. They think changing ESPs will improve their delivery. The problem is delivery is often poor because the ESP lets customers send to purchased lists. Purchased lists usually perform poorly because many list sellers are not very conscientious about permission.

These are the big ESPs that drive the market and they don’t allow purchased lists. There’s a reason for this. ESPs that allow purchased lists don’t have great delivery. Their customers send a lot of unwanted and unsolicited email and it taints all the mail coming from their space. I’ve done work for a couple ESPs that that had all their client mail, even the permission stuff, going to bulk at places like Yahoo! and Gmail.
Purchased lists drive delivery problems.
What’s more, the ESP reps know when customers say other-esp lets us send to purchased list it may not be true. I’ve heard at least 3 or 4 of the above ESPs listed as allowing purchased lists. But they don’t. Sure, some customers can, and probably do, get away with purchasing lists and mail them off the ESP. But if they get caught they’re either disconnected or they’re told to stop sending to the purchased list.
Many ESPs prohibit the use of purchased address lists and for good reasons.
Note: if you’d like your ESP added to this list, please contact me (email or in the comments) with a link to your published no purchased lists policy and I’ll add you here.

Email verification services

Just yesterday a group of delivery folks were discussing email verification services over IRC. We were talking about the pros and cons, when we’d suggest using them, when we wouldn’t, which ones we’ve worked with and what our experiences have been. I’ve been contemplating writing up some of my thoughts about verification services but it’s a post I wanted to spend some time on to really address the good parts and the bad parts of verification services.
Today, Spamhaus beat me to the punch and posted a long article on how they view email verification services. (I know that some Spamhaus folks are part of that IRC channel, but I don’t think anyone was around for the discussion we had yesterday.)
It’s well worth a read for anyone who wants some insight into how email verification is viewed by Spamhaus. Their viewpoints are pretty consistent with what I’ve heard from various ISP representatives as well.
In terms of my own thoughts on verification services, I think it’s important to remember that the bulk of the verification services only verify that an address is deliverable. The services do not verify that the address belongs to the person who input it into a form. The services do not verify that an address matches a purchased profile. The services do not verify that the recipient wants email from the senders.
Some of the services claim they remove spamtraps, but their knowledge of spamtraps is limited. Yes, stick around this industry long enough and you’ll identify different spamtraps, and even spamtrap domains. I could probably rattle off a few dozen traps if pressed, but that’s not going to be enough to protect any sender from significant problems.
Some services can be used for real time verification, and that is a place where I think verification can be useful. But I also know there are a number of creative ways to do verification that also check things like permission and data validity.
From an ESP perspective, verification services remove bounces. This means that ESPs have less data to apply to compliance decisions. Bounce rate, particularly for new lists, tells the ESP a lot about the health of the mailing list. Without that, they are mostly relying on complaint data to determine if a customer is following the AUP.
Spamhaus talks about what practices verification services should adopt in order to be above board. They mention actions like clearly identifying their IPs and domains, not switching IPs to avoid blocks and not using dozens or hundreds of IPs. I fully support these recommendations.
Email verification services do provide some benefit to some senders. I can’t help feeling, though, that their main benefit is simply lowering bounce rates and not actually improving the quality of their customers’ signup processes.

Email verification – what are we verifying

One of the ongoing discussions in the email space is the one about address verification. Multiple companies have sprung up to do “real time” email address verification. They ensure that addresses collected at the point of sale are valid.
But what does valid mean? In most of these contexts, valid means that the addresses don’t bounce and aren’t spam traps. And that is one part of validating email addresses.
That isn’t the only part, though. In my opinion, an even more important thing to validate is that the email address belongs to the person giving it to you. The Consumerist has had an ongoing series of articles discussing people getting mis-directed email from various companies.
Today the culprit is AT&T, who are sending a lot of personal information to an email address of someone totally unconnected to that account. There are a lot of big problems with this, and it’s not just in the realm of email delivery.
The biggest problem, as I see it, is that AT&T is exposing personally identifiable information (PII) to third parties. What’s even worse, though, is that AT&T has no process in place for the recipient to correct the issue. Even when notified of the problem, support can’t do anything to fix the problem.
