We deal with a nonlocal interaction equation describing the evolution of a particle density under the effect of a general symmetric pairwise interaction potential, not necessarily in convolution form. We describe the case of a convex (or $\lambda$-convex) potential, possibly not smooth at several points, generalizing the results of CDFLS. We also identify the cases in which the dynamic is still governed by the continuity equation with well-characterized nonlocal velocity field.
