Sales is a relatively complicated subject for most people, as once again, the words you choose are everything. The type of sales techniques that work on each person can vary greatly.

Email subject lines have a direct effect on the following marketing points:

  • Encouraging reader engagements and click-through rates
  • Increasing open rates
  • Creating a personalized connection with each customer or audience member

Subject line mistakes to avoid

This article offers plenty of direction on how to write an email subject line, but it’s also important to know what to avoid when writing.

Some of these common mistakes include:

  • Writing the subject line in all caps
  • Never make false promises you can’t follow through on
  • Using language that deceives the reader
  • Being overly vague

These are seen as common as people do it all the time, but they can negatively affect the open rates of your emails. People don’t respond positively to all-caps subject lines, lies, or non-descriptive information.
