Email filters

What makes the best email filter? There isn’t really a single answer to that question. Different people and different organizations have different tolerances for how false positives versus false negatives. For instance, we’re quite sensitive to false positives here, so we run extremely conservative filtering and don’t block very much at the MTA level. Other people I know are very sensitive to false negatives and run more aggressive filtering and block quite a bit of mail at the MTA level.
For the major ISPs, the people who plan, approve, design and monitor the filters usually want to maximize customer happiness. They want to deliver as much real mail as possible while blocking as much bad mail. Blocking real mail and letting through bad mail both result in unhappy customers and increase the ISP’s costs, either through customer churn or through support calls. And this is a process, filters are not static. ISPs roll out new filters all the time, sometimes they are an improvement and sometimes they’re not. When they’re not, they’re pulled out of production. This works both for positive filters like Return Path and negative filters like blocklists.
Then there is mail filtering that doesn’t have to do with spam. Business filters, for instance, often block non-business mail. Permission of the recipient often isn’t even a factor. Companies don’t often go out of their way to block personal mail, but if personal mail gets blocked (say the vacation plane ticket or the amazon receipt) they don’t often unblock it. But when you think about why a business provides email, it makes perfect sense. The business provides email to further its own business goals. Some personal usage is usually OK, but if someone notices and blocks personal email then it’s unlikely the business will unblock it, even if the employee opted in.
In the case of email filters, the free market does work. Different ISPs filter mail differently. Some people love Gmail’s filters. Other people think Hotmail has the best filtering. There are different standards for filtering, and that makes email stronger and more robust. Consumers have choices in their mail provider and spamfiltering.

Blocking of ESPs

There’s been quite a bit of discussion on my post about upcoming changes that ESPs will be facing in the future. One thing some people read into the post is the idea that ISPs will be blocking ESPs wholesale without any regard for the quality of the mail from that company.
The idea that ESPs are at risk for blocking simply because they are ESPs has been floating around the industry based on comments by an employee at a spam filter vendor at a recent industry conference.
I talked to the company to get some clarification on what that spam filtering company is doing and hopefully to calm some of the concerns that people have.
First off, and probably most important, is that the spam filtering company in question primarily targets their service to enterprises. Filtering is an important part of this service, but it also handles email archiving, URL filtering and employee monitoring. The target market for the company is very different than the ISP market.
The ISPs are not talking about blocking indiscriminately, they are talking about blocking based on bad behavior.
Secondly, this option was driven by customer request. The customers of the spam filtering appliance were complaining about “legitimate” mail from various ESPs. Despite being reasonable targeted the mail was unrequested by the recipient. While ESPs use FBLs and other sources of complaints to clean complainers off rented or epended lists at ISPs, the option is not available for mail sent to corporations. Enterprises don’t, nor should they have to, create and support FBLs. Nor should employees be expected to unsubscribe from mail they never requested.
This option is the direct result of ESPs allowing customers to send spam.
Thirdly, this option is offered to those customers who ask for it. It is not done automatically for everyone. The option is also configurable down to the end user.
While I haven’t seen the options, nor which ESPs are affected, I expect that the ones on the list are the ones that the filtering vendor receives complaints about. If you are not allowing your customers to send spam, and are stopping them from buying lists or epending, then you probably have not come to the attention of the filtering company and are not on the list of ESPs to block.

The answer is 42

I continually run into companies that don’t really have a goal or understanding of their email marketing program. They’ve never really asked questions about how they’re using email or even why email is the right answer. Lots of companies are also diving head first into email marketing or the social media craze without having thought about what their goals are and what they want to happen.
What regularly ends up happening to companies that jump in without a clear goal is they get into a situation where their delivery is bad. Then they read a lot of best practice advice on the net and try to implement all of it. Sometimes that works, but other times it doesn’t. Finally they hire me or another consultant to help them sort out where it all went pear shaped.
My consulting isn’t about rote recitation of common best practices. Instead, I want to know about a client’s business and what they think about email.  The most frequent question I ask clients is: How does email fit into your business? What are your goals for your business? What is your value proposition?
Some of my clients can’t answer these question. They just tell me they want to use email and they don’t know what they’re doing and that’s why they hired me. Well, I can help them successfully send email, but I can’t help them decide what role email plays in their business. Those are the decisions my client needs to make. I can’t set their business goals for them.
When was the last time you actually sat down and just thought about your business goals? I know that sometimes it’s hard to find the time to look at your business and where it’s going. “Think about it? I’m too busy doing it!” But every business person needs to look at their business goals.
Once you’ve thought about your goals, think about your email marketing program. Is email helping you to reach those goals? How?
If you’ve reached your current business goals, what are your next ones? And how does email fit into those goals?
Sure, having an answer is good, but are you actually asking the right question?

Comments on Holomaxx post

I’m putting together a longer analysis of the Holomaxx case that will look at the claims against the various defendants. There’s some deep mis-understanding of how various things works (hint: wiretapping? not so much).
There was one comment from “The Other Barry” about complaints that I think bears highlighting.
