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.
