“One form of cliff-hanger is easily recognized, the three dotted end. This is the email subject line that ends with… Examples:
1. On the second day of Christmas…
2. Mr. Grey Will See You Now… (50 shades of Grey promotion)”
To spark engagement in your readers, and make them want to act on your message, use some inspiration when it comes to your subject lines. The dotted cliff-hanger works by leaving the burning question of “What will happen next?”
