When serving a company by certified mail, the letter must be addressed to a specific corporate officer, a managing or general agent, or another agent authorized to receive service of process on the company’s behalf. Service cannot be accomplished by merely mailing a copy of the summons and complaint to the company to be received along with the general mail sorted by lower-level employees. Taylor v.
