How it Works
A customer engagement strategy is a plan to increase customer satisfaction by having more positive interactions with them. It can be through any channel, from in person, to online, to over the phone. Great strategies take customer engagement from reactive to proactive.
When possible, never let a customer leave without some sort of connection. It doesn't have to be a full-fledged loyalty program, either.
An email newsletter will work, or even a Facebook like.
Just some way of maintaining their exposure to your brand.
