Organizational security and doxxing

The security risks of organizational doxxing. 
These are risks every email marketer needs to understand. As collectors of data they are a major target for hackers and other bad people. Even worse, many marketers don’t collect valid data and risk implicating the wrong people if their data is ever stolen. I have repeatedly talked about incidents where people get mail not intended for them. I’ve talked about this before, in a number of posts talking about misdirected email. Consumerist, as well, has documented many incidents of companies mailing the wrong person with PII. Many of these stories end with the company not allowing the recipient to remove the address on the account because the user can’t prove they own the account.
I generally focus on the benefits to the company to verify addresses. There are definite deliverability advantages to making sure email address belongs to the account owner. But there’s also the PR benefits of not revealing PII attached to the wrong email address. With Ashley Madison nearly every article mentioned that the email address was never confirmed. But how many other companies don’t verify email addresses and risk losing personally damaging data belonging to non customers.
Data verification is so important. So very, very important. We’ve gone beyond the point where any big sender should just believe that the addresses users give them are accurate. They need to do it for their own business reasons and they need to do it to prevent incorrect PII from being leaked and shared.

Yes, Virginia, there is list churn

Yesterday I talked about how data collection, management, and maintenance play a crucial role in deliverability.  I mentioned, briefly, the idea that bad data can accumulate on a list that isn’t well managed. Today I’d like to dig into that a little more and talk about the non-permanence of email addresses.
A common statistic used to describe list churn is that 30% of addresses become invalid in a year.  This was research done by Return Path back in the early 2000’s. The actual research report is hard to find, but I found a couple articles and press releases discussing the info.

It's not about the spamtraps

I’ve talked about spamtraps in the past but they keep coming up in so many different discussions I have with people about delivery that I feel the need to write another blog post about them.
Spamtraps are …
… addresses that did not or could not sign up to receive mail from a sender.
… often mistakenly entered into signup forms (typos or people who don’t know their email addresses).
… often found on older lists.
… sometimes scraped off websites and sold by list brokers.
… sometimes caused by terrible bounce management.
… only a symptom …

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.
