For a soft graviton we confirm the results, obtained in Ref. [24] using just gauge invariance, up to terms of ${\\cal O}(q^1)$ for external tachyons and up to terms of ${\\cal O} (q^0)$ for external massless closed string states. Furthermore, we also derive the behavior of the scattering amplitude when a dilaton or a Kalb-Ramond field becomes soft.
