An interview follow up email, is an email that a job candidate sends to an employer immediately after a job interview. These emails are intended to be a final chance for candidates to show the hiring manager why they should be selected for the job. The email follow up messages are not intended to be a sales pitch, but rather a way for candidates to thank the hiring organization for their time.
Candidates who follow up with employers are more likely to be successful candidates, because employers will be aware of any interview feedback they have received. It can help to increase your chances.
