Radiatively generated neutrino masses ($m_\nu$) are proportional tosupersymmetry (SUSY) breaking, as a result of the SUSY non-renormalisationtheorem. In this work, we investigate the space of SUSY radiative seesaw modelswith regard to their dependence on SUSY breaking($\require{cancel}\cancel{\text{SUSY}}$). In addition to contributions fromsources of $\cancel{\text{SUSY}}$ that are involved in electroweak symmetrybreaking ($\cancel{\text{SUSY}}_\text{EWSB}$ contributions), and which aremanifest from $\langle F^\dagger_H \rangle = \mu \langle \bar H \rangle \neq 0$and $\langle D \rangle = g \sum_H \langle H^\dagger \otimes_H H \rangle \neq0$, radiatively generated $m_\nu$ can also receive contributions from$\cancel{\text{SUSY}}$ sources that are unrelated to EWSB($\cancel{\text{SUSY}}_\text{EWS}$ contributions). We point out that recentliterature overlooks pure-$\cancel{\text{SUSY}}_\text{EWSB}$ contributions($\propto \mu / M$) that can arise at the same order of perturbation theory asthe leading order contribution from $\cancel{\text{SUSY}}_\text{EWS}$.  We show that there exist realistic radiative seesaw models in which theleading order contribution to $m_\nu$ is proportional to$\cancel{\text{SUSY}}_\text{EWS}$. To our knowledge no model with such afeature exists in the literature. We give a complete description of thesimplest model-topologies and their leading dependence on$\cancel{\text{SUSY}}$. We show that in one-loop realisations $L L H H$operators are suppressed by at least $\mu \, m_\text{soft} / M^3$ or$m_\text{soft}^2 / M^3$. We construct a model example based on a one-looptype-II seesaw. An interesting aspect of these models lies in the fact that thescale of soft-$\cancel{\text{SUSY}}$ effects generating the leading order$m_\nu$ can be quite small without conflicting with lower limits on the mass ofnew particles.
