The sledgehammer of confirmed opt-in

We focused Monday on Trend/MAPS blocking fully confirmed opt-in (COI) mail, because that is the Gold Standard for opt-in. It is also Trend/MAPS stated policy that all mail should be COI. There are some problems with this approach. The biggest is that Trend/MAPS is confirming some of the email they receive and then listing COI senders.
The other problem is that typos happen by real people signing up for mail they want. Because MAPS is using typo domains to drive listings, they’re going to see a lot of mail from companies that are doing single opt-in. I realize that there are problems with single opt-in mail, but the problems depends on a lot of factors. Not all single opt-in lists are full of traps and spam and bad data.
In fact, one ESP has a customer with a list of more than 50 million single opt-in email addresses. This sender mails extremely heavily, and yet sees little to no blocking by public or private blocklists.
Trend/MAPS policy is singling out senders that are sending mail people signed up to receive. We know for sure that hard core spammers spend a lot of time and money to identify spamtraps. The typo traps that Trend/MAPS use are pretty easy to find and I have no doubt that the real, problematic spammers are pulling traps out of their lists. Legitimate senders, particularly the ESPs, aren’t going to do that. As one ESP rep commented on yesterday’s post:

I work for an ESP and we don’t suppress domains like this, based on the theory that if a client is hitting spamtraps, we want to know so we can sanction or terminate them. But if Trend are acting in bad faith here, I guess my best bet is just to suppress any domain of theirs I can find (and it took about 30 seconds to find 2700 of them).   Another Anon

That’s a sentiment I heard over and over again from companies listed by Trend/MAPS. The companies are happy to force their customers to clean up their acts.  They want reports of bad behaviour by customers, but Trend/MAPS policy of forcing confirmations is taking a sledgehammer to kill a fly.

I think we have a reputation of being a bit harsh on customers, and we’re honestly a little proud of that. But I’m most proud of the fact that we are always fair and honest, even with the bad people.
We tell people what they need to change. The bad people who won’t take our advice are easy to kick out after that.
In this particular situation, we don’t have any advice to give. We don’t have a way to tell people “go do this.” Because it would be a lie. “Go remove inactives” won’t help. “Go re-confirm inactives” won’t help. Even “Go use double opt-in” won’t help if MAPS is clicking and opening everything.
And because MAPS is who they are, we can’t provide a lot of detail to customers, either.  An ESP Executive

COI is a tool. It is occasionally a good tool for keeping lists clean. But I’ve worked with dozens of senders over the year that aren’t using COI and are still keeping their lists clean because they have other processes in place to do so.

Changes at Gmail

As I’ve said before, I can usually tell when some ISP changes their filtering algorithm because I start getting tons and tons of calls about delivery problems at that ISP. This past month it’s been Gmail.
There have been two symptoms I’ve been hearing about. One is an increase in bulk folder delivery for mail that previously was reliably hitting the inbox. The other is a bit more interesting. I’ve heard of 3 different mailers, with good reputations and very clean lists, that are seeing 4xx delays on some of their mail. The only consistency I, and my colleagues at some ESPs, have identified is that the mail is “bursty.”
The senders affected by this do send out mail daily, but the daily mail is primarily order confirmations or receipts or other transactional mails. They send bi-weekly newsletters, though, exploding their volume from a few tens of thousands up to hundreds of thousands. This seems to trigger Gmail to defer mail. It does get delivered eventually. It’s frustrating to try and deal with because neither side is really doing anything wrong, but good senders are seeing delivery delays.
For the bulk foldering, Bronto has a good blog post talking about the changes and offering some solid suggestions for how to deal with them. I’m also hearing from some folks who are reliable that Gmail may be rolling back some of the bulk foldering changes based on feedback from their users.
So if you’re seeing changes at Gmail, it’s not just you.

Is your mail being bulk foldered?

Daisy at Signup.to posted a list of 11 things to do when mail is going to the bulk folder. Her suggestions are a good start to troubleshooting and fixing persistent bulk foldering of mail.
One thing she doesn’t mention is that while bulk foldering can sometimes be the result of poor content, more often it’s the result of unengaged recipients. Think of bulk foldering this way: the ISP has some subscribers they’re pretty sure want your mail, so they’re not going to block your mail. But they’re pretty sure a lot of subscribers don’t want your mail so they’re not going to deliver it to the inbox.
The trick to getting mail moved out of the bulk folder is to get more people engaged with your email marketing. This is tough to do if they’re not actively checking their bulk folder for mail but there are some ways I’ve helped clients get mail into the inbox.

A Disturbing Trend

Over the last year or so we’ve been hearing some concerns about some of the blacklisting policies and decisions at Trend Micro / MAPS.
One common thread is that the ESP customers being listed aren’t the sort of sender who you’d expect to be a significant source of abuse. Real companies, gathering addresses from signup forms on their website. Not spammers who buy lists, or who harvest addresses, or who are generating high levels of complaints – rather legitimate senders who are, at worst, being a bit sloppy with their data management. When Trend blacklist an IP address due to a spamtrap hit from one of these customers the actions they are demanding before delisting seem out of proportion to the actual level of abuse seen – often requiring that the ESP terminate the customer or have the customer reconfirm the entire list.
“Reconfirming” means sending an opt-in challenge to every existing subscriber, and dropping any subscriber who doesn’t click on the confirmation link. It’s a very blunt tool. It will annoy the existing recipients and will usually lead to a lot of otherwise happy, engaged subscribers being removed from the mailing list. While reconfirmation can be a useful tool in cleaning up senders who have serious data integrity problems, it’s an overreaction in the case of a sender who doesn’t have any serious problems. “Proportionate punishment” issues aside, it often won’t do anything to improve the state of the email ecosystem. Rather than staying with their current ESP and doing some data hygiene work to fix their real problems, if any, they’re more likely to just move elsewhere. The ESP loses a customer, the sender keeps sending the same email.
If this were all that was going on, it would just mean that the MAPS blacklists are likely to block mail from senders who are sending mostly wanted email.
It’s worse than that, though.
The other thread is that we’re being told that Trend/MAPS are blocking IP addresses that only send confirmed, closed-loop opt-in email, due to spamtrap hits – and they’re not doing so accidentally, as they’re not removing those listings when told that those addresses only emit COI email. That’s something it’s hard to believe a serious blacklist would do, so we decided to dig down and look at what’s going on.
Trend/MAPS have registered upwards of 5,000 domains for use as spamtraps. Some of them are the sort of “fake” domain that people enter into a web form when they want a fake email address (“fakeaddressforyourlist.com”, “nonofyourbussiness.com”, “noneatall.com”). Some of them are the sort of domains that people will accidentally typo when entering an email address (“netvigattor.com”, “lettterbox.com”, “ahoo.es”). Some of them look like they were created automatically by flaky software or were taken from people obfuscating their email addresses to avoid spam (“notmenetvigator.com”, “nofuckinspamhotmail.com”, “nospamsprintnet.com”). And some are real domains that were used for real websites and email in the past, then acquired by Trend/MAPS (“networkembroidery.com”, “omeganetworking.com”, “sheratonforms.com”). And some are just inscrutable (“5b727e6575b89c827e8c9756076e9163.com” – it’s probably an MD5 hash of something, and is exactly the sort of domain you’d use when you wanted to be able to prove ownership after the fact, by knowing what it’s an MD5 hash of).
Some of these are good traps for detecting mail sent to old lists, but many of them (typos, fake addresses) are good traps for detecting mail sent to email addresses entered into web forms – in other words, for the sort of mail typically sent by opt-in mailers.
How are they listing sources of pure COI email, though? That’s simple – Trend/MAPS are taking email sent to the trap domains they own, then they’re clicking on the confirmation links in the email.
Yes. Really.
So if someone typos their email address in your signup form (“steve@netvigattor.com” instead of “steve@netvigator.com”) you’ll send a confirmation email to that address. Trend/MAPS will get that misdirected email, and may click on the confirmation link, and then you’ll “know” that it’s a legitimate, confirmed signup – because Trend/MAPS did confirm they wanted the email. Then at some later date, you’ll end up being blacklisted for sending that 100% COI email to a “MAPS spamtrap”. Then Trend/MAPS require you to reconfirm your entire list to get removed from their blacklist – despite the fact that it’s already COI email, and risking that Trend/MAPS may click on the confirmation links in that reconfirmation run, and blacklist you again based on the same “spamtrap hit” in the future.
