Low complaint rates are not always good

Digging another old blog post out of the archives. In November 2011, I talked about how part of the Holomaxx complaint against Microsoft and Yahoo said that their complaint rates were below 0.5% and 0.1%. The argument was that if their complaint rates were low, then the mail must not be spam.

Specifically, HolomaXx alleges, its Microsoft complaint rates have been consistently at or below 0.5 percent and its Yahoo complaint rates have been at or below 0.1 percent.
Spam-complaint rates are a significant metric ISPs use to determine if incoming email is wanted by recipients or not.

Senders still seem to focus on the complaint rate. The problem is they don’t understand how ISPs measure the complaint rate. First off 0.5% is actually a high complaint rate. More importantly ISPs only allow complaints for mail that makes it to the inbox. If mail is blocked during the SMTP transaction or filtered into the bulk folder, users cannot complain.
I’ll say it again, because it is critically important to understand.
Bad senders who do not get email to the inbox have very low complaint rates.
Why? ISPs measure complaints as a percentage of the emails that make it to the inbox. If mail is not hitting the inbox then the complaint rates are zero.
I understand this is a bit of a catch 22, in that to get a good reputation you need to get mail to the inbox and to get mail to the inbox you need a good reputation. But I hear a lot of spammers tell me they absolutely can’t be sending spam because their complaint rates are so low and it’s just not true.

How useful are feedback loops

Things are extremely busy here and blogging is going to be light for a few weeks. I’ll be reposting some older blog posts that are still relevant for today’s email senders.
Today’s post is a repost from November 2008. I look at the whys and hows of FBLs, address some of the objections people had to them and discuss how senders should deal with FBL mail.
There has been a very long, ongoing discussion on one of my mailing lists about whether or not feedback loops are a net good or a net harm. I believe, overall, they are a net good, but there are people who believe they are not. The biggest objection is that the lawyer mandated redaction of the To: address combined with the fact that some users use the “this is spam” button to delete unwanted email, makes it difficult for some FBL recipients to sort out the real issues from the cruft.
Redaction can be a problem for some senders, particularly for the small mailing list hosted as a hobby or contribution to the community. In order to effectively deal with FBL emails, a sender needs to have tools on the email sending side and on the FBL receiving side. This is often more overhead than the volunteer list maintainer wants to handle. Unfortunately, these senders are a minority and therefore their issues are often not addressed by the ISPs.
Some of the objections and complaints about “broken” or “useless” FBLs come from people who do not really have any history for the FBLs, where they are, what they were designed for and who their target audience is. A bit of history may help explain why things are how they are.
The First FBL
The “this is spam” button evolved from the “notify AOL” button. This button was a way email recipients could notify AOL staff about any number of problems, including threats, viruses and other unwanted emails. As time went on, this was changed to “this is spam” to encourage users to report more spam so the AOL would have the data to make delivery decisions. Eventually, AOL made the decision to share that data with some senders and ISPs. The lawyers made the decision to redact the “To:” address, but not make any other changes to the message because they believe they should not be sharing subscriber email addresses with third parties. As some people correctly point out, the lawyers are not interested in hearing from non lawyers about changing this. It is possible that another lawyer may be able to put together a position paper and convince them this stance is overly cautious. I am pretty sure, though, that no one without a legal degree will be given any audience from them.
Given the success of the AOL FBL and the demand from both ESPs and ISPs for FBLs, other ISPs started offering FBLs as well. Many of them also redacted the To: address, either just following AOL’s lead or under advice of their own counsel.
That means, as senders, we are in a situation where we really cannot make the ISPs change what they’re doing. We can either adapt our own mailing practices to cope with them or we can forego the data provided by the FBL. One of the challenges in choosing to shun the whitelist at AOL that in order to qualify for whitelisting, you have to accept a FBL. For ISPs, who want to whitelist their outgoing MTAs, but have customers sending mail, maybe running small mailing lists, or who are forwarding mail to their ISP account, this can be a problem. However, any ISP needs some sort of abuse desk automation, and this automation should be able to handle FBLs. This can also be a problem for small ESPs or companies doing in-house email marketing. They buy something off the shelf to handle mail (or install mailman) that does not do VERP or otherwise enter the specific address in the email. When faced with a redacted email they cannot do anything with the complaint.
What does the FBL email tell the FBL recipient?
This really depends on what role the FBL recipient plays in the mail transport system. Bandwidth and network service providers use the FBL as an aggregate tool. They really only deal with FBL complaints if there is a change in complaint volume about an IP, they don’t treat each complaint as a valuable source of information. Typically what happens is that an ISP abuse desk notices a spike in complaints. After investigation, they may discover that a customer machine is compromised. They then notify the customer, the customer patches or disconnects the machine and the problem is fixed.
ESPs tend treat the FBL as an unsubscribe mechanism as well as a way to monitor customers. A few FBL complaints are not necessarily a sign that the sender is spamming, but once a threshold is reached the ESP delivery / abuse team addresses the issue. Spammers can get FBLs and often use them as a way to clean lists of complainants. Some really dirty spammers even suppress those complainants from all their lists.
Is a FBL useful?
This is really something that someone else cannot tell you. Some companies find FBLs to be extremely useful, even after they have had to make investments in software (either off the shelf like our Abacus software, or something custom written internally) to send mail that will survive the FBL redaction process and to handle the actual FBL email. Some companies find the FBLs to be more trouble than they are worth. The question, however, is really one only the sender can answer.
Overall, I think FBLs are more helpful than they are harmful. They do require investment on both sides of the transaction, but does encourage senders and receivers to cooperate with one another.

Clarification on monetizing complaints

There has been quite an interesting discussion in the comment stream of my earlier post about monetizing the complaint stream. I’ve found all the perspectives and comments quite interesting.
There is one thing multiple people have brought up that I don’t necessarily see as a problem. They assert that this idea will only work if all ESPs do it because customers can just say, “Well, Other ESP will let us do this and not charge us.”  I don’t quite understand why this is an issue. Customers already do this.  In fact, sometimes the assertion is actually true.
There are ESPs that let customers spam. There will always be ESPs that let customers spam. This is not new. Changing a pricing model isn’t going to change this.
As I was envisioning the monetization process, ESPs who wanted to do this could actually offer multiple tier pricing. The customer can choose a lower price point for their overall mail program, while assuming the cost of their recipients complaining. Or the customer can choose a higher price point and let the ESP absorb the cost of handling complaints. In either case, the customer would still have to meet the ESP’s standards for complaints and comply with their TOS.
Clearly I’m seeing the idea and industry differently than a lot of my readers. I’m interested to hear the thought process behind this so I can better understand the objection.

Unsubscribing from spam, part 2

Yesterday I posted about why the reasons a lot of people give for not unsubscribing from spam are mostly wrong. Unsubscribing from spam doesn’t seem to confirm your address and it doesn’t seem to increase your spam load.
But does that mean you should unsubscribe from spam? I’m not sure about that.
I’ve been working on a project where I am unsubscribing from every message coming into one of my email addresses. Weeks into that process I’m not seeing a huge decrease in the amount of mail that address is receiving. In some cases I’m unsubscribing from the same senders multiple times a day and have been for close to 3 weeks.
While unsubscribing doesn’t increase your spam, I’m also not sure it decreases your spam, either. But I’ll have full data and numbers demonstrating that in a few more weeks.
What can have an effect on the amount of spam you get is complaining about spam, at least according to Brian Krebs.
