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.

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.

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.

Monetizing the complaint stream

What if ESPs (and ISPs, for that matter) started charging users for every complaint generated? Think of it like peak pricing for electricity. In California, businesses can opt for discounted power, with the agreement that they are the first companies shut off if electrical demand exceeds supply. What if ESPs and ISPs offered discounted hosting rates to bulk senders who agreed to pay per complaint?
I see pricing scheme something like this.
