Write an email from a social media coach to her client about how the client's posts need to be more authentic and engaging... not just focusing on asking for the sale in every post. You can make up names for the coach and client. Keep the email below 200 words and make the tone friendly... as if delivering the news gently.

Maria, 

I looked over your most recent posts! I feel you are heading in the right direction. I see strong calls to action with lots of encouragement to click sales links. 
However, I think you need to tie in more authenticity and opportunities for your audience to engage. 
Weave your story into the sales pitch. Why did you create this? Why are you passionate about it? How will it change things for the buyer if they choose to purchase? 
Ask questions that your audience can engage with, as it relates to your story. Things like "Have you ever felt like this?"  or "Tell me your experience with XYZ!". 
Again I feel you're really heading in the right direction, you just need these tweaks!
Can't wait to see what you come up with!

Best,
Lucia
