@priyanka27 Thanks Priyanka! I would say that if you have 50k followers on social, you can get subscribers fairly easily by posting a signup link to your newsletter.
Easy - Email list because you control your data.
Let's assume for a moment that you can get a 3% conversion rate of your email = 150 conversions
Trying to convert 150 on any social platform is going to consumer a TON more time and energy to say nothing of money.
That's a tough choice! An email list of 5k subscribers can give you direct access to your audience, while a following of 50k on social platforms can provide broader visibility. It ultimately depends on your goals and strategy - quality vs. quantity, engagement vs. reach. Can't go wrong with either, just different strokes for different folks!
