Hence I included 'Politely', I should have also included I've been doing this for ~ 2 years.

My primary mode of communication is email, 100% for professional communication. Yes, there are people who are offended when I impose such communication criteria and I've lost business opportunities.

But thoughtful communications due to non-real-time nature of email has qualitatively increased and not having to touch the phone often has resulted in better physical and mental health(the whole reason for me making these major changes in first place)[1].
