# listar_clientes

Lista tus clientes (modo clientes, para asesorías y gestorías) junto con las alertas que nutren a cada uno: esas alertas describen qué vigila cada cliente, así que son el contexto para decidir a qué cliente pertenece cada entrada del inbox. Úsala para '¿qué clientes tengo?' o antes de asignar entradas. Requiere tener el modo clientes activado.
