Filtering is not just about spam

A lot of filters started out just as filters against spam. But over the years they’ve morphed into more general blocks against dangerous or problematic email. There’s a lot of crime and bad behavior on the internet, much of it using email as a conduit or vector. Filtering is so much more than stopping spam now. It’s as much, or more, about stopping crime.
Email filters are essential to protect us from scammers. Sometimes I forget this, and then I read about a grandmother getting swindled by a Nigerian scammer and ending up dead.
There are real consequences to poor filtering and there is real crime facilitated by email. It’s easy to forget this as we deal with the email that gets caught in filters when they shouldn’t.
Filters are one of the first lines of defense against online crime.
Not only does filtering stop crime, but they also keep email working. An unfiltered mail stream is an ugly, unreadable, unworkable mess.

Email marketing firm smacked by the SEC

Yes, the SEC. Really.
Apparently the email marketing firm mUrgent, which provides services to the restaurant and hospitality industry also had a side business. According to the complaint filed by the SEC last month, they had an entire boiler room set up to sell shares for their non-existent IPO.
I’d never heard of this firm before, so I did a little digging. First step, check out their website.

Filters and windmills

A colleague of mine was dealing with a client who is experiencing some difficulty delivering to the bulk folder. Said client spent much of a one hour phone call repeating “This is not how a free society works!!”
After the call my colleague commented, “I refuse to get ranty about filter systems.”
I know that filters, and the people who write and maintain them, are a frequent scapegoat for senders. The filters are always the problem, not anything the senders do.
Now, I’ll be the last person who will claim spam filters are perfect, they’re not. Filters sometimes do unexpected things, sometimes they do boneheaded things, sometimes they are broken.
We can’t forget, though, that filters perform a vital role in protecting users from malicious emails. Phishing emails, scams, fake products, viruses are a constant threat. Many end users don’t need to worry about this because filters are so good. But an unfiltered account can get thousands of scams and spams a day (ask me how I know).
Most of us in the delivery space can tell when a filter is working as intended and when there’s an underlying problem. And when the filter is working as intended there’s not a lot of use complaining about them. Ranting about filtering systems often delays a resolution. Senders that focus on what they can control tend to have more success reaching the inbox than those senders that focus on ranting about filtering systems.
Tilting at windmills doesn’t get the mail through.

Working as intended

There’s a certain type of sender that thinks every ISP block or email delivered to the bulk folder is a false positive. They’re so sure that the filters aren’t actually supposed to catch their mail that they’ll spend any amount of money and do every possible thing to get their mail to the inbox.
The problem for these senders, though, is that their mail is exactly the type of mail filters are designed to catch. They’re sending mail without recipient permission. I’m not talking about the lists that get a few typos or problem addresses on them. I’m talking about senders that buy and trade mailing lists. I’m talking about senders that don’t believe they have to have permission to send mail.
This mail getting filtered is a sign that the filters are working as intended. They’re keeping the unsolicited email out.
A lot of us take for granted that all commercial mail, at least that isn’t selling fake watches or herbal viagra, is always sent with permission. But there’s an awful lot of mail out there that doesn’t even have a minor fig leaf of permission. Filters stop that mail. And senders have very little recourse when they do.
