Email marketing has been around for about as long as email has existed. We could spend all day on the nuances of what separates a good email subject line from a great one or an awkward subject line from a truly disastrous one, but that is not the purpose of this article.

No matter the industry, email client, nor demographic there are simple, research backed keywords that are proven to either increase or decrease open rates. I have poured over white papers, brand guides, and countless other resources to compile the ultimate list of over 200 keyword dos and don’ts so you can be a master of the inbox.

This article assumes you have basic knowledge of the structure of emails, what email subject lines, keywords, and preview text are as well as a general understanding of open rates.

These subject line keywords are commonly used words or phrases that have been tested over time across industries. Many are even applicable to other types of emailing such as a job interview follow-up.
