We advocate effective field theory to analyse new physics in the lepton sector. When the new states are out of experimental reach, the only parameters relevant for phenomenology are the Wilson coefficients of higher dimensional operators, obtained by decoupling the heavy states. We illustrate the advantages of such effective description for a few representative models of neutrino masses, which may induce a variety of low-energy leptonic observables.
