Language as filtering criteria

A few months ago I was working on a delivery audit for a client who sends mail in multiple languages. We discovered that the language of an email has a significant delivery impact. The same email in different languages was delivered differently, particularly at Gmail. Emails in a language I don’t normally receive email in were delivered to my bulk folder.
Other folks have commented on similar things. Some filters really do look at preferred language of the recipient and treat mail in other languages as problematic. I don’t think that’s unreasonable. I do get a lot of foreign language spam and there’s no real way to stop it. Many countries don’t require opt-out links, and so there isn’t a clear way to even unsubscribe.
Writing in the recipient’s local language is one way to minimize inappropriate blocking, even when you have permission to send mail.

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.

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.

Light blogging for a while

Sorry for the lack of substantive posts, things seem to have gone completely out of control and I’m not finding a lot of extra cycles to sit down and blog. I’ll try and get some stuff up this week, but I’m also getting ready for MAAWG and the sessions I’m a part of there.
There was an interesting post by Romer over on his personal blog. If you don’t know, Romer helps maintain one of the commercial mail filters. He recently got spammed by one of his vendors and talked about how this is probably not the best idea. Al adds his own take on companies assuming permission. I’ve talked about taking permission in the past but haven’t touched on things like “spamming the guy who runs the filter.”
You’d be surprised, or maybe you wouldn’t, about how many people who run filters for large organizations get spammed regularly. You wouldn’t be surprised to find out that those people do factor in their own personal spam load when adjusting their organizational filters.
