While many marketers use brackets at the beginning of email subject lines, new data from subjectline.com shows placing them at the end is boosting open rates.

Data from Subjectline.com reveals a powerful, simple tactic for email marketing. Using a "continuation pre-header" that begins with "and," "but," or "plus" creates a narrative link to the subject line, sparking curiosity and significantly boosting open rates.
