Email marketing is one of the most effective ways to engage customers and drive sales, but only if your messages actually reach their inboxes. Spam filters are getting smarter, and using certain words can land your emails in the junk folder before they ever get seen. To maximize deliverability and keep your campaigns effective, it’s important to avoid common spam trigger words and phrases.
At Stratagem Designs, we specialize in creating high-converting email campaigns that reach your audience without setting off spam filters. Below, we’ll explore the top spam trigger words and provide alternative phrasing to keep your emails in the clear.
Why Spam Filters Flag Certain Words
Spam filters analyze subject lines and body content to detect patterns commonly associated with fraudulent or overly promotional emails. Words that imply urgency, financial gain, or unrealistic promises often get flagged. Additionally, excessive capitalization, too many exclamation points, and misleading claims can contribute to deliverability issues.
