the condition of gauge invariance suggests that they have zero mass, just as in electromagnetism.

thus the ratio of the electron's mass to its charge, when both are measured in planck units, grounds the relative strengths of gravitation and electromagnetism.
thus the ratio of the electron charge to the electron mass (in natural units) determines the relative strengths of electromagnetic and gravitational interaction between two electrons.
