Customer Satisfaction and Feedback through notes to customer

Hi,

I wanted to know. If we manually reach out to each of our customers through the “note to Customer” area at the bottom of each order, and make sure they’re happy and possibly would consider leaving a positive review, or feedback, will that trigger any negative spam alerts or hurt our standing as a site on our host or anything basically awful that we aren’t aware of?

I really want to be hands on and make sure people are happy with what they buy, but I never know what types of hidden alarms there are out there on the interwebs.

Thank you in advance for making me smarter on this subject in advance.
