Using Ms. or Mrs. in a cover letter depends on whether or not you know the marital status of the woman. If you are ever uncertain, it is always safe to use Ms. because it does not make an assumption about her marital status.
When writing a cover letter to mail or to upload to a job board or company website, the first section of your cover letter should include information on how the employer can contact you. When you send an email cover letter, include your contact information in your signature instead of listing your contact information at the top of the message.
