Whether your personal email address is used for company-wide communication depends on the organization's policies and practices. In some cases, personal email addresses may be used for general communication; in others, the organization may provide official company email addresses. It is important to know that an employer cannot compel you to provide or use your personal email accounts for work-related activities, even though it is a common practice. In these cases, you may want to sign up for a new email account with one of the many free services available.
