What’s the best time of day to reach out to clients?

[Btaliat]

Globally, some freelancers have argued that morning is the best time that a freelancer should be reaching out to clients. With this, they have not been stressed from works. They still have the energy to talk, being convinced and even willing to work with the freelancers. When it is in the afternoon, they must have gotten tired. The stress from works and some other disturbances. And in the night, they would have been tired. They just want to sleep. What do you think?
