Email marketing is as much an art as it is a science. You want your subject lines to effectively capture the attention of your recipients and entice them to click, but you also don’t want to risk being flagged as spam. Unfortunately, email platforms are becoming more intuitive by the day, which means if you’re not careful, your messages could easily end up rerouted before they ever even reach your readers.

One of the easiest ways to avoid triggering spam filters is to choose the words you use in your subject line very carefully. To make things a little easier, we’ve put together a rather exhaustive list of common email spam trigger words. Feel free to bookmark this post and consult back whenever you’re crafting an email message.
