In this paper we introduce and investigate three new subclasses of $$p$$-valent analytic functions by using the linear operator $$D_{\lambda,p}^m(f*g)(z)$$. The various results obtained here for each of these function classes include coefficient bounds, distortion inequalities and associated inclusion relations for $$(n,\theta)$$-neighborhoods of subclasses of analytic and multivalent functions with negative coefficients, which are defined by means of a non-homogenous differential equation.
