Tune Up Your Email Newsletter To Be Compliant With Anti-Spam Filters by Julia Gulevich

In this article we'll continue talking about how to create a healthy email message and give a few tips how to survive anti-spam filters. Anti-spam filters catch every incoming email before it is delivered into the inbox and review it. They use a scoring system to classify an email as spam or legitimate. These filters (you might have heard about SpamAssassin, SpamProbe, or SpamCombat) look for certain patterns in the message, and assign "spam points" to it based on certain criteria: words, phrases, or even colors.

Depending on what these filters find or don't find in the message, points are added to or taken away from a scoring system. If the message score is 5.0 or higher, the filters add the *SPAM* word to the subject line of the message and the email is redirected to a "bulk" or "junk" mailbox. The lesser the score the better.

So, one of the main concerns when writing an email newsletter is to ensure that it is structured in a way that will allow it "pass" this test. I'll go to the point and give you a few tips you may follow:

1) Check what you put in the subject line
The subject line is one area of your e-mail that is carefully examined. For example, if you type a recipient's name in the message subject like "To: [recipient's name]", your message will get 2.86 points because of this. If there is a lot of white space in the subject line, the email gets 2.64 points added to the score. The word FREE written in caps "weighs" additional 1.10 points.
If you put a date into the subject line, you can take off 0.48 points. And you can take one full point off if your subject contains a newsletter header!

2) Keep your message size from 20K to 50K
The size of the message does matter for anti-spam filters. The majority of spam emails are less than 20K. So, you can actually get 0.71 taken from your score if your message in within the 20K to 50K range.

3) Be wise with CAPS
If you use too many capital letters in your message, you'll get 0.21 points added to your score. So, use them wisely!

4) Use full hyperlinks
If you use a hyperlink in your email, make sure you put the http:// at the beginning. A spam filter will add 1.28 points to your emails if you don't!

5) Be restrained with colors
Different colors do matter too. Blue adds 0.21 points, red 0.33 points, and Magenta 0.44. The background color other than white adds 0.317 points to the message score. The Black is optimum as it won't add or take any points off.

6) Be a welcome guest
Send your recipients an e-mail after they have "opted in" at you site, and have them confirm that yes, you have permission to send the newsletters to them. This will help in the case if you need to prove you are not spamming, and that people want to receive the emails from you.
Have your recipients add you to their address books or white lists and your messages won't have to pass through anti-spam filters.

7) Beware of Blacklists!
Blacklists are databases of known spammers that ISPs regularly check. You may be added to a blacklist without you knowing it if one of your recipients clicks on the "this is spam" button. If you are blacklisted, contact the server provider immediately.

8) Test your message
Use a spam checker to test your message before you send it out to the world. A message content checker can help locate potential problems prior to distribution. It runs your receiver and sender addresses, subject line, and message content past a collection of rules. It then reports the result and tells you whether your message is likely to be filtered. Most checkers suggest a score of 5.0 will get your email sent to the spam scrap heap. One of our favorite free checkers is the Lyris' Content Checker. Lyris ContentChecker filters your message through several hundred Spam Assassin tests to determine if it has characteristics typical of unsolicited "spam" mail. Just fill in the blanks, including your email text or the full HTML coding, and submit it. You'll get an instant score on the next screen and a more detailed report by return email. This report highlights the factors used to evaluate your message, and may help you to make further improvements to it.

9) Don't use the "spammers" e-mail software
Anti-spam filtering systems are aware of some of the favorite email programs that professional spammers use and they add on as many as 3 points if you send the messages with those program. Be sure to check the ISP's "hit list" to see what email software are on it. Remember that the anti-spam filters are not perfect and they often happen to be "over protective". They can give the "false negatives" and "false positives" results after the message analysis. A false negative is when a pure spam email gets through the filter, and a false positive is when a legitimate email ends in the "junk" box flagged as spam.

Around 150 companies now offer spam filtering software. The number of anti-spam techniques is growing and anti-spam technology is getting "smarter" too. For example, some servers (challenge systems) send an email back to the original sender and require a reply before they forward the email to the recipient. The idea behind this is that only a human can reply to a request for specific information. America Online recently announced a new spam filter that can actually "learn" the preferences of each of their subscribers.

Anti Spam techniques by Sakuraba

Anti-spam techniques The US Department of Energy Computer Incident Advisory Committee (CIAC) has provided specific countermeasures against electronic mail spamming.

Some popular methods for filtering and refusing spam include e-mail filtering based on the content of the e-mail, DNS-based blackhole lists (DNSBL), greylisting, spamtraps, enforcing technical requirements, checksumming systems to detect bulk email, and by putting some sort of cost on the sender via a Proof-of-work system or a micropayment. Each method has strengths and weaknesses and each is controversial due to its weaknesses.

Detecting spam based on the content of the e-mail, either by detecting keywords such as "viagra" or by statistical means are very popular. They can be very accurate when they are correctly tuned to the types of legitimate email that an individual gets, but they can also make mistakes such as detecting the keyword "cialis" in the word "specialist". The content also doesn't determine whether the email was either unsolicited or bulk, the two key features of spam. So, if a friend sends you a joke that mentions "viagra", content filters can easily mark it as being spam even though it is both solicited and not bulk.

The most popular DNSBLs are lists of IP addresses of known spammers, open relays, zombie spammers etc.

Spamtraps are often email addresses that were never valid or have been invalid for a long time that are used to collect spam. An effective spamtrap is not announced and is only found by dictionary attacks or by pulling addresses off hidden webpages. For a spamtrap to remain effective the address must never be given to anyone. Some black lists, such as spamcop, use spamtraps to catch spammers and blacklist them.

Enforcing technical requirements of the Simple Mail Transfer Protocol (SMTP) can be used to block mail coming from systems that are not compliant with the RFC standards. A lot of spammers use poorly written software or are unable to comply with the standards because they do not have legitimate control of the computer sending spam (zombie computer). So by setting restrictions on the mail transfer agent (MTA) a mail administrator can reduce spam significantly. In many situations, simply requiring a valid fully qualified domain name (FQDN) in the SMTP's EHLO (extended hello) statement is enough to block 25% of incoming spam.

Obfuscating message content Many spam-filtering techniques work by searching for patterns in the headers or bodies of messages. For instance, a user may decide that all e-mail he or she receives with the word "Viagra" in the subject line is spam, and instruct her mail program to automatically delete all such messages. To defeat such filters, the spammer may intentionally misspell commonly-filtered words or insert other characters, as in the following examples:
V1agra Via'gra V I A G R A Vaigra \ /iagra Vi@graa The principle of this method is to leave the word readable to humans (whose pattern-recognition skills make them adept at picking out the true meaning of misspelled words), but not recognizable to a literally-minded computer program. This is effective up to a point. Eventually, filter patterns become generic enough to recognize the word "Viagra" no matter how misspelled -- or else they target the obfuscation methods themselves, such as insertion of punctuation into unusual places in a word.
(Note: Using most common variations, it is possible to spell "Viagra" in over 1,300,000,000,000,000,000,000 ways.)

HTML-based e-mail gives the spammer more tools to obfuscate text. Inserting HTML comments between letters can foil some filters, as can including text made invisible by setting the font color to white on a white background, or shrinking the font size to the smallest fine print.

Another common ploy involves presenting the text as an image, which is either sent along or loaded from a remote server. This can be foiled by not permitting an e-mail-program to load images.

As Bayesian filtering has become popular as a spam-filtering technique, spammers have started using methods to weaken it. To a rough approximation, Bayesian filters rely on word probabilities. If a message contains many words which are only used in spam, and few which are never used in spam, it is likely to be spam. To weaken Bayesian filters, some spammers, alongside the sales pitch, now include lines of irrelevant, random words, in a technique known as Bayesian poisoning. A variant on this tactic may be borrowed from the Usenet abuser known as "Hipcrime" -- to include passages from books taken from Project Gutenberg, or nonsense sentences generated with "dissociated press" algorithms. Randomly generated phrases can create spamoetry (spam poetry) or spam art.

After these nonsense subject lines were recognized as spam, the next trend in spam subjects started: Biblical passages. A program much like Mark V Shaney is fed Bible passages and chops them up into segments. The reasoning is that this text, very different from the writing style of today, will confuse both humans and spam filters.

Another method used to masquerade spam as legitimate messages is the use of autogenerated sender names in the From: field, ranging from realistic ones such as "Jackie F. Bird" to (either by mistake or intentionally) bizarre attention-grabbing names such as "Sloppiest U. Epiglottis" or "Attentively E. Behavioral". Return addresses are also routinely auto-generated

Best Anti Spam Product - 5 Tips To Kill Spam by Shortstuff48

While we still get junk mail in the post box it's no where near has annoying has the spam in our Inbox. Even though it causes no waste in the dumps and doesn't consume earth's resources it takes one precious thing away and that is time.
Have you been looking for the best way to decrease spam or stop it all together? Well my friend the best anti spam product is YOU!
Yes if you are proactive you can avoid most spam. With a little forethought and planning you can alleviate yourself from spam. Bear in mind however it is impossible to get rid of spam completely.

However these tips below should and will help:
1.) Never click on a un-subscribe link unless you subscribed to the message yourself. This only tells the sender that this address is a "real live address" and someone read the message.

2.) Never post your address in newsgroups or web pages. If you must do so then try some form of masking your address so a bot cannot scour the page and harvest your address.
Example: user@nobody.com is a bad idea to post but user[at]nobody[dot]com is a safer way. If someone really wants to write you they can decipher your address themselves. Also email harvesters should have a harder time getting your address.

3.) If you must use an address to sign up for a service that you aren't sure of or you want a free download etc then have a secondary address for those occasions. Make sure you log in and check this account to delete the junk mail in bulk so your account doesn't get deleted. Also never give this address to friends or else you may not get the message because you inadvertently deleted it with the spam.

4.) If you have a website and you want the email to go to your address use a web based submission form.

5.) Run your own email.
Personally I have my own domain and run several email addresses and forwarders so I can delete and create them at will. This can be done cheaply too.
All you need is a domain name which you can get from Namecheap.com or Godaddy.com for under $10. They do provide email hosting but I prefer to do it myself using a web hosting provider. Some I've used in the past are hostdime.com hostony.com and surpasshosting.com.
Most hosting providers also have their own spam blocking software installed.

For a last line of defense you can get software installed on your machine to sort or filter spam. You can learn a lot more on ending your spam nightmare and make email enjoyable again, this software can help you. It is the best anti spam filtering software.

Now that you know that you yourself can be the best anti spam blocker take the last step and end the spam nightmare by giving yourself that last line of protection.
