Unsubscribe

Unsubscribe – a term used in email marketing to describe the action when the email recipient requests to be excluded from any future communications through mass mailing.

Some marketers see the unsubscribe feature only as a legal requirement that is enforced upon them. However if managed correctly, the unsubscribe can become a very valuable list management tool.

The email marketing is not all about the quantity of the emails sent, it is all about the quality. It does not matter how many emails you send if your email is irrelevant to the recipient. For this reasons you have to keep your lists as clean as possible and make sure that only those people receive your emails that are interested in what you have to say.

It is a good practice to add the “report abuse” link at the top of the email. This will reduce the chance of being reported as being a spammer. The emails should go to abuse@yourdomain.com and forwarded to your email address. I strongly suggest you respond to those emails asap and even give them a call  to explain why they received your email if necessary. The people on the other line will be pleasantly surprised by talking to real human being instead of receiving an autoreply “Thank you for your message. We will deal with your enquiry as soon as we can be bothered.” In the end it is all about the relationship with the customer.

Blacklisting

Blacklists are a very effective way of fighting spam. It affects the UCE vendors and deliverers directly. The domains that send masses of emails to addresses that do not exist or being rejected, because of the message contents (Hard/Soft Bounce) are being added to the blacklists. The email recipients Internet Service Providers (ISP’s) and Email Service Providers (ESP’s) match the sender domain and the landing page domains against the known blacklists to determine whether it is listed. If so, the email is being marked as spam.

To stop spammers crawl the web searching for email addresses, ISP’s, ESP’s and blacklist owners such as SPAMHAUS Project publish email addresses on random blogs (spam trap address). Those email addresses serve no other purpose than wait for emails to start coming in. Every message sent to those email addresses indicate that the email address was automatically scraped off the website in order to be marketed and the sender domain has to be blacklisted.

Blacklists are a powerful tool of cleaning the web of the unwanted mail. However this is a big problem for legitimate email marketing companies as this can affect their entire internal email delivery. Most blacklists take a long time to be cleared and often blacklist owners charge a fee for the domain to be de-listed.

Bayesian filters

Was trying to say something clever abour bayesian filters, however there is no way anyone would be able to describe bayesian filters better than SPAM filter guru Paul Graham.

“To the recipient, spam is easily recognizable. If you hired someone to read your mail and discard the spam, they would have little trouble doing it. How much do we have to do, short of AI, to automate this process?

I think we will be able to solve the problem with fairly simple algorithms. In fact, I’ve found that you can filter present-day spam acceptably well using nothing more than a Bayesian combination of the spam probabilities of individual words. Using a slightly tweaked (as described below) Bayesian filter, we now miss less than 5 per 1000 spams, with 0 false positives.

The statistical approach is not usually the first one people try when they write spam filters. Most hackers’ first instinct is to try to write software that recognizes individual properties of spam. You look at spams and you think, the gall of these guys to try sending me mail that begins “Dear Friend” or has a subject line that’s all uppercase and ends in eight exclamation points. I can filter out that stuff with about one line of code.”

Full article: http://paulgraham.com/spam.html

And in contrast I came acoross a great comment about the problems byasian filters are up against.

[..] “Bayesian filters, which is one layer of defence in an anti-spam system, attempts to classify mails as “good” or “spam” based on content. It studies samples of mail received in your inbox and builds a database of words found in spam mail (“viagra, penis, enlarge etc”) and words found in good mail (normal words). Thereafter, it analyses mails and if it finds words in it that are prevalent in spam, it marks it as spam – but on the other hand, if it finds words in the mail that are normally found in good mail, it marks it as good.

By including random normal words in their spam – that make no sense in the context of the spam, but are perfectly good words otherwise, the spammers are trying to fool the bayesian filter into classifying these words as spam. once this happens, legitimate mail with these words will get classified as spam, leading you to doubt the accuracy of the spam filter, and eventually (they hope) get you to disable it as it becomes progressively useless.. That’s the theory at least.”
