Top 5 Most Popular Spam Subject Lines

Here’s a look at the most popular spam subject lines.

1. Blank subject line- Whether it’s done out of laziness, forgetfulness or because they think it tempts curious recipients, most spam is sent without any subject line at all or “No Subject”.
2. Amazon.com Deal of the Day- This subject line is attached to millions of very realistic looking emails that claim to be from the popular e-tailer.  The spammers are hoping people will not realize Amazon doesn’t have a Deal of the Day promotion and fall for the phishing attempt. Amazon accounts are attractive to cybercriminals because they almost always have a credit card attached to them.
3. Please Read- Simple and humble, this subject line is still quite effective. Apparently being polite does make a difference.
4. Delivery Status Notification (Failure)- This subject line has a double meaning. It’s used to get a recipient’s attention and more importantly to get them to open the message, and it works well. Bounced mail is something most become concerned about. While it’s usually attached to fake bounce notifications with links that lead to spammy sites, this subject line also shows up in the inboxes of people who have had their email address spoofed. In that case they are real bounces.
5. Replica Watches- Fake designer goods like watches, handbags, and shoes are big business for spammers. These spam messages are particularly popular over the holidays and lead to either fake storefronts that steal credit card info or to Chinese websites that sell cheap junk watches and other designer knock-offs.
