Most people quickly scan the subject lines in their inbox before deciding which messages are worth their time and attention. With so much pressure on the subject line to entice the potential reader, we thought it would be interesting to see how much of a difference a single word can make in a campaign’s open rate, and what words can help your overall email marketing strategy and boost open rates.
To get some answers, we studied approximately 24 billion delivered emails with subject lines composed of approximately 22,000 distinct words. If you think that sounds like a lot of data, you’re right. We looked at subject lines both in general and within specific industries.
