With Black Friday approaching, have you thought about how you're going to treat your new customers?
The time from when they place their order, until a few days after they receive their package are a critical time for their ongoing behavior. Handle that well and they might convert to a repeat customer. Handle it poorly and well... you've seen what customer behavior can devolve into.
The gold-standard is having a new customer welcome campaign that messages them about how to benefit from their order. Benefit. Not just use or track their order, but actually receive benefits from what they ordered.
I've written about new customer welcome campaigns in past articles.
The important thing now is to have something up and running. Even if it's just a single email, that's going to be much better than most stores. You can always build on it from there.
