Dear AK Saini,
Mastering skills was never easy task and neither will it be. If it were to be so easy then world would have been far different place.
Google or any other website or our good old books can only give you the knowledge. Conversion of this knowledge into the skills requires guidance and supervision of some instructor.
You need to take a formal training on "E-mail and Business Writing Skills". Further you need to practice lot. Then only you can master these skills.
I have conducted this programme on E-mail writing several times. Recently one of the members of this forum attended my training and later uploaded her comments. You can click the following link to check her comments:

It will be my pleasure to conduct similar training for you.
Thanks,
