Why is it important to test sending an electronic résumé before sending it to an employer?

It is extremely important to test sending an electronic resume before sending it to an employer. This is because the test will allow you to see the resume as the employer will see it. This means that if there any mistakes in it (spelling, formatting, etc.) you will be able to see them before you send the final copy. Moreover, this will allow you to ensure that the resume is sent in the way you want it to be, and that it is legible for the employer.
