As account-based marketing (ABM) becomes more attractive for companies seeking to improve how their sales and marketing teams engage with current or prospective customers, it’s common to adopt a named-account strategy that identifies a list of accounts where marketing is asked to deliver tactics on a one-to-few or one-to-many approach.
