This thought has just occurred to me now, I have been building an email list from solo ads (95%) since August 2015.
Also also building a social media following & most of my best business partners (+ sales) have joined me/come from from my social media building efforts.
Building an email list is expensive but building social media following costs almost nothing apart from your time.
The email lists of subscribers takes forever to warm up to you but social media followers interact with you straight away.
So Should I Build My Email List Or Social Media Following ? Times are changing !
