Spam: CAN-SPAM and other solutions

This article summarizes in the most concise way possible the purpose and components of the CAN-SPAM Act, as well as discussing its implications and workarounds for spam.

The CAN-SPAM Act: What it does

Generally speaking, CAN-SPAM (Controlling the Assault of Non-Solicited Pornography And Marketing) applies to emails sent to recipients in the US. It attempts to provide a degree of protection to consumers from various forms of email messages commercial email, requested or unsolicited. It does this by imposing requirements on the sender of the emails. Does not apply to recipients outside of the US Different requirements and restrictions apply in other countries.

The following are key aspects and requirements of the Law:

• It does not prevent unsolicited email from being sent to a recipient, but it does allow the recipient to respond to a sender, for example, by opting out of receiving further communications from that particular sender.
• Opting out of communications from a sender does not prevent other senders from continuing to send messages to that recipient.
• The Law applies to individual emails as well as emails sent in bulk.
• The “From” line of the email must contain correct and accurate information.
• The ‘Subject’ line should be closely related to the content of the message.
• The sender must include a valid physical address. PO Boxes and other purchased addresses are acceptable as long as they can be traced back to the sender.
• An appropriate tag should be added if the message includes adult material.
• An option to unsubscribe must be included. It must also be easy to use (for example, it does not require a password).
• “Transactional” emails (for example, an invoice from a previous purchase) can still be sent to recipients even after they have unsubscribed.
• You should not send a message using a collected email address.
• If the recipient has not given their express consent (opt-in) to receive the email, then the message should be labeled as an advertisement.

How effective is CAN-SPAM?

While many reputable email senders adhere to the CAN-SPAM rules, traditional spammers generally do not and continue to send spam.

It is estimated that between 200 billion and 300 billion emails were sent daily in 2010. That represents an annual volume in the region of 100 trillion emails.

Of those 100 billion, an estimated 90 billion consisted of spam or viruses.

The vast majority of the 90 billion did not adhere to national recommendations for generating email as CAN-SPAM.

Even worse; In many cases, unsubscribe lists are not used for compliance, but are used to validate email addresses in order to sell them to other spammers to generate more spam.

Stop Spam: Workarounds

Although some high-profile lawsuits have been launched against some prominent spammers, the CAN-SPAM Act is generally not rigidly enforced in court.

Consequently, the main defense against spam has been the use of antispam software applications.

However, there is much wisdom in the saying that prevention is better than cure.

A powerful spam prevention strategy is to prevent spammers from getting your email address in the first place. Simple methods can be used, but discipline is required.

For example, just because it’s illegal to harvest email addresses doesn’t mean it won’t happen. So if you make your email address visible on a forum (eg Craigslist), there is a high chance that a spammer will get it.

It’s a constant battle between spam and antispam. But the consensus currently favors the latter.
