The weird thing about sending an email to your subscribers is that you don't know how your readers are reacting to your post. You cannot see their body language or their facial expression.

Are they receptive to your idea.? Do they understand what you are trying to tell them?

Do you feel like you are talking to the wall?

I guess this is the limitation of an email.

The good news is that there is a solution to it - by adding something to it.
That something is your Facebook group. Invite your email subscribers to comment on your same post inside your Facebook group. That means you post the same content twice - once in your Facebook group and then in your email autoresponder.

If you want to encourage more people to sign up, share more juicy details in the email. Those who did not subscribe will miss out the best parts.

Email + Facebook is the best combination. You have the best of both worlds - the guaranteed access to your readers via email and the responsiveness through an online community.

I love to hear your feedback through Facebook Messenger. I enjoy having a private one to one chat with my readers. It is more intimate and personal. If you are benefitting from my sharing, do encourage me to keep sharing. If I know it is helpful, I will continue to do awesome work.
