Radiative decays $D^*_{(s)}\to D_{(s)}\gamma$ are revisited in light of newexperimental data from the \textit{BABAR} and BESIII collaborations. Theradiative couplings $g_{D^*D\gamma}$ encoding nonperturbative QCD effects arecalculated in the framework of the covariant confined quark model developed byus. We compare our results with other theoretical studies and experimentaldata. The couplings (in $\textrm{GeV}^{-1}$) $|g_{D^{*+}D^+\gamma}| = 0.45(9)$and $|g_{D^{*0}D^0\gamma}| = 1.72(34)$ calculated in our model agree with thecorresponding experimental data $|g_{D^{*+}D^+\gamma}|=0.47(7)$ and$|g_{D^{*0}D^0\gamma}|=1.77(16)$. The most interesting case is the decay$D^*_s\to D_s\gamma$, for which a recent prediction based on light-cone sumrules at next-to-leading order $|g_{D^*_s D_s\gamma}|=0.60(19)$ deviates fromthe first (and only to date) lattice QCD result $|g_{D^*_s D_s\gamma}|=0.11(2)$at nearly $3\sigma$. Our calculation yields $|g_{D^*_s D_s\gamma}|=0.29(6)$,which falls somehow between the two mentioned results, although it is largerthan those predicted in other studies using quark models or QCD sum rules.
