A cover letter is typically submitted when there is a specific job opening that you are applying for. It serves as an introductory letter that accompanies your resume and highlights your qualifications, skills, and experiences that make you a suitable candidate for the position. It also allows you to personalize your application and demonstrate your interest in the company or organization.

If there is no job opening, it may not be necessary to send a cover letter. However, in some cases, you may still choose to send a letter of interest or an inquiry letter to express your interest in working for the company and inquire about potential future job openings.
