As an email marketing manager, you might think that only evil people would send spam. But unfortunately, that’s not the situation here.

Spam filters are notoriously inaccurate; even legitimate email marketers have had messages marked as spam.

There is a lot more spam than you may realize.

Spam accounts for 71% of all emails on average.

This figure changes wildly from month to month.

While the proportion of spam emails was 48% in April 2018 (significantly down from 80% in February 2014), this still means that half of all emails will be deleted without being read.

The Real Figures Behind Email Spam

A staggering 14.5 billion messages per day are spam, meaning that 45 percent of all email traffic is spam.

Research firms approximate that spam email accounts for as much as 73% of all emails sent worldwide.

One of the leading sources of spam email is the U.S., with Korea coming in at number two.

An estimated 36% of all spam messages are related to advertising, making it the most common type of spam.

About 31.7% of all spam is related to adult content, making it the second most popular type. By far, the third most common type of spam, 26.5 percent, is money-related.

Identity theft (phishing) accounts for 73 percent of all spam emails, but scams and fraud account for only 2.5 percent.

As a result of spam’s pervasiveness in both personal and business email, people’s and businesses’ attitudes toward it have changed.

In fact, polls show that people are less likely to trust communications over the Internet because of spam.

In 2005, researchers found that due to spam, 53 percent of respondents had lost faith in email as a reliable means of communication.

In a recent survey, 52 percent of businesses said that cutting down on spam was their top priority.

However, there is an expectation in the fight against spam due to tools like spam blockers.

About 2.4 billion spam emails per day are stopped by MSN alone.

Email spam will always be a problem, though.

But you can protect yourself and your information from spam and other online threats by taking some simple precautions.

1. Use Spam Filters

Some level of spam filtering is typically built into your email service in the form of a dedicated spam folder; however, you may be able to fine-tune your provider’s spam protections as needed.

In addition, you may set up your own filters in your inbox depending on the criteria you specify, allowing you to allowlist specific senders.

2. Make Sure No One Else Can Access Your Email Address

Microsoft Security warns against sharing your email address in public places like message boards or social media to avoid having it “harvested” by spammers.

3. Make Sure You’re Using Individual Accounts For Your Email

Separate personal email accounts, or even a temporary “throwaway” email for some online payments, are another approach to cut down on spam.

You can always create a new account if your temporary account is affected. 

According to Art Sturdevant, vice president of technical operations at the security firm Censys, “most email services enable you to set up a temporary email address, and that assists with filtering.”

7. Examine Messages Carefully

A few spam emails are spam. You might think you’re getting an email from PayPal, but when you hover your mouse over the sender’s name, you might be taken to a completely different website.

Also, check for typos and grammatical mistakes that could attempt to trick spam filters.

8. Don’t Respond To Spam

Keep from replying to spam emails. Norton warns that replying to an unwanted message alerts the sender that the account is still active, which could lead to further messages of this nature being sent to the user.

9. Use Caution Before Clicking “Unsubscribe”

If you were receiving emails only from reliable senders, you could easily opt out of receiving them and greatly reduce your exposure to spam.

Email addresses are often “spoofed” by cybercriminals because they don’t play by the same rules.

Officials have warned that clicking the unsubscribe link could take you to a malicious website. Rather than ignoring spam, report it and help your email provider’s spam filter learn.

Final Thoughts

It appears that the 2020–2021 period saw a significant increase in spam rates due to the widespread fear caused by the covid-19 pandemic, as evidenced by data collected thus far.

Many organizations, including charities, unintentionally lose funding due to false positives in spam filters caused by phishing and other financial scams.
