2.9 billion. That’s the number of projected worldwide email users by the end of 2019. In other words, one-third of the entire population of the world is hearing “You’ve got mail!” on a regular basis.
But even with an ever-growing number of messages ending up in our mailboxes each week, email remains the preferred channel of communication for most consumers. In fact, more than 70% of them rank it as their top channel for marketing communications.
Since your audience is open to connecting and receiving email from you, it’s important to put this valuable tool to good use as you build your marketing strategy.
In order to make sure your email marketing efforts are effective, you need to ensure your prospects are receiving your messages. That means understanding email spam filters and figuring out how to avoid being trapped in them. Here’s what you need to know.
How do spam filters work?
There are different types of spam filters, all of which work to keep junk out of people’s mailboxes. Some are provided by the email service; others are customizable by the recipient.
- Header filters: These filters review email header content for suspicious information, including IP addresses typically associated with spammers or mass copies of the same email sent to groups.
- Content filters: These filters are more sophisticated and review the content of a message for specific words and patterns that indicate spammy behavior. Examples include overuse of money-related words, like “free,” “discount,” and “lottery”; adult terminology; or words that push overly-urgent action, like “hurry” or “last chance.” While a single incidence of these words may not be enough to trigger the content filter, they should be used judiciously.
- Language filters: These filters can remove any emails not in the recipient’s native language. Similar filters can also be used to block emails that come from outside the recipient’s country.
- General blacklist filters: These filters stop all emails that come from a blacklisted file of known spammers.
- Rules-based filters: These filters are created by the user to sift out emails that don’t give them value. The user may choose to filter out certain senders or phrases in an effort to reduce the spam making its way into their inbox.
As with all technology, spam filters are continually improving and becoming more sophisticated, with newer iterations analyzing text within images or reviewing the context in which specific words and phrases are used.
How can I get my marketing emails past the spam filters?
With so many spam filter pitfalls out there, and so many potential opportunities to trip yourself up, what can you do to give yourself the best chance of landing in your prospects’ inboxes?
1. Maintain a clean email list
If your email list contains outdated addresses or unengaged subscribers, you’re probably not getting the delivery rates and open rates you’d hoped for. When that happens, your messages are seen as less relevant, and that can play a factor in whether you’re sent to spam or not.
Using email verification tools can give you a quick and easy option to clean up your list and boost engagement rates from your users by creating a higher ratio of engaged recipients.
2. Exclude the “fancy” stuff
Emails should have a good balance of text to images and other information. Building emails that are all image and no text, all code and little text, or that have “fancy” embedded information like Flash files or video, can drag you down and create the appearance of spaminess.
3. Create good subject lines
Just as subject lines can affect your recipient’s engagement with your product, those first impressions can have an impact on your ability to make it into inboxes at all. Sixty-nine percent of email recipients choose to report messages as spam based on the email subject line alone, so create subject lines that are relevant, useful, and low on exclamation points and ALL CAPS.
4. Invest time and resources into making your email content engaging
If you create content your recipients want to read, you’ll earn a better sender score. If your content is boring or overly salesy, more of your prospects may mark it as junk or ignore it, both of which can affect your credibility and lead to your messages being trapped in spam filters. Understand the elements that convey credibility. Don’t claim expertise you don’t have. It’s too easy to check someone’s background these days to risk your reputation on falsehoods.
5. Don’t use spam trigger words
The best way to avoid being sent to spam is to … well, avoid acting like spam. Using spam trigger words can increase the possibility of being trapped in a spam filter. When you’re creating an email, find ways to convey relevancy and value, but avoid the following terms and phrases, or use them sparingly:

Trying to navigate spam filters can be frustrating, especially if you’re in an industry that relies heavily on some of these terms (think banking, financial services, and marketing in particular).
However, you may just need to think creatively and use your storytelling skills to go beyond feature-oriented terms and highlight the benefits you can provide to potential customers.
As a businessperson or a marketing professional, you’re investing time and money into creating a product or service your customers need, then spending even more time and money on putting together exceptional communications to spread the word about your company.
However, even your best marketing is only as good as its deliverability rate. Avoiding these trigger words won’t automatically put you at the top of your prospect’s mailbox, but it can help your chances.
The rest is up to you.
