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.

The writing doesn’t have to be too bold or in your face to be effective; it simply has to catch the eye of the recipient. This can easily be done by playing into their interests while hiding something they might want with the email inside.

In addition to learning how to craft compelling subject lines, it's also crucial to consider the email subject line for after an interview. Making a lasting impression post-interview can significantly impact your candidacy.

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
