In the world of Email Marketing, it is critical to develop a positive reputation as a sender. Following industry established Email “Best Practices” are helpful to ensure proper development of a positive sending reputation.
In email subject lines and in the body of the email campaign itself, the use of proper keywords is critical. The wrong keyword can trigger spam filters and increase the likelihood of email being sent to the spam folder or even blocked entirely.
The following list is 328 words, symbols, and phrases to avoid using in subject lines and within the body of the email. Some are obviously more likely to cause delivery issues than others, but each of these words carries a high spam rating and, when possible, should be avoided.
