Account-based marketing (ABM) is a strategy that businesses use to focus their marketing efforts on a specific group of potential customers. It's like having a custom marketing plan just for them. With ABM, companies create personalized messaging and offers for each customer or group of customers. This is different from traditional marketing, which typically involves sending the same message to a large group of people. With ABM, the message is customized for each customer, helping to build strong relationships with them.
