Any message that comes in the subject line referring to sex, money, or reduced airfares can safely be avoided. The same is true for any messages that claim to offer vacation deals, tax relief, or miraculous cures. Other words that should be banished from subject lines are:

  • free
  • exclusive
  • first time
  • make money now
  • limited-time only
  • naked
  • incredible
  • adults only
  • a one-time offer
  • act now
