A student organization is developing promotions for its clothing fundraiser. Email blasts across campus will be part of the campaign. The following are subject line features that might explain whether promotional emails are opened:
the number of words in the subject line
using the recipient’s name in the subject line
including humor in the subject line
posing a question in the subject line
including the name of a well-known community member
