You've spent hours crafting the perfect email campaign, but your open rates are disappointing. The problem might not be your content, but specific words that trigger spam filters. In this article, we'll explore the top spam trigger words and how to replace them with more effective alternatives.
Understanding Spam Filters
Email service providers use sophisticated algorithms to protect users from unwanted emails. These filters analyze various elements of your email, including the content, sender reputation, and specific keywords that are commonly associated with spam.
When your email contains too many of these trigger words, it's more likely to be flagged as spam or sent directly to the promotions folder, where it might never be seen by your intended recipient.
Note: Even if you have permission to email someone, using spam trigger words can still negatively impact your deliverability.
