Phone Call vs. Live Chat

Hello,

I'm working on setting up my digital marketing agency. We will be generating leads through cold emailing. I never liked the phone call and was thinking to implement a live chat in the sales process.

My question is can we successfully close clients via live chat rather than through the phone call?

Please feel free to share your input and experiences.

Phone calls have a more personal touch to it so getting that would definitely get higher conversion rates.

No one likes phone calls but it gives as @AquaticGamer said more personal touch to it.
Try and test it for yourself, if you can, of course.
All the best.
