Hi @prajwalbkumar ,
Thank you for taking the time to reply me.
Since you have affirmed the issue, guess there is really no other way around it. I have stumbled upon this thread Email subscribers without publishing a post - #2 by DavidDarnes, but it is a partial and a little complex way to do what you are mentioning as well.
Hopeful there is some simple implementation in the near future as well!
Thanks for sharing man! Cheers!
