The next time you go to register a new domain name for your company, consider the point of contact that you specify. Technically, the administrative contact in your domain name records indicates the manager or owner of that name. When the registrar needs to communicate about important issues including billing and renewals for that domain name, they will use the email contact on file in that record.
I recommend specifying a management level or ownership level contact in the “administrative” section of your domain record, and specifying a different alternative contact for the “billing” contact, such as your accounting department email address or another partner in the business. This way, if one of the original contacts is not available during key communications, or if one of those email addresses becomes invalid, you will still have an easy way of getting information about your domain name and can continue to manage it via the 2nd contact.
More importantly, make sure the official company name is indicated in the Organization fields. If there is ever a dispute about your domain name or if you need to acquire managing information, you need a way to demonstrate that the domain name is tied to the company rather than just an individual.
