Generally, an account manager for a mailing house is assigned to a particular account, responsible for maintaining the relationship with the client on a day to day basis. Essentially, they are the primary port-of-call for clients utilising the services of direct mail companies, and are the go-to person.
Account managers at a mailing company, for instance, typically have multiple accounts to work on, although may solely work with a high-value business should the client require their services. Hand in hand with direct mail management, however, comes expertise and the guarantee that you are doing all you can to get your brand in front of the right people.
