Correspondence max

What Is the maximum number of correspondence games you may play simultaneously

I think I can play 50 (I tried on chesscom). But as I sometimes get busy, I stopped to play too much and short time control.

Uma vez no chesscom estava com 200 partidas 7+

Comecei a ficar cansado mentalmente e acabei perdendo metade das partidas, apenas fazia o lance sem analizar
