This^^^.
Fishcouple, one of my customers did the same! She sent me a convo and raved about the item she purchased from me (my other shop). I never ask for reviews, but since she was so happy with the item I told her I would really appreciate it if she would leave a review. I explained, step by step, how she could do it.
The sweet lady gave me a raving review, but in a convo to me! It warmed my heart and I just thanked her, but did not insist.
