Mailchimp would like to talk to you about customers.

A customer is what happens when marketers fail to personalise their marketing,

grouping customers with very different behaviours into one tangled mess.

But with Mailchimp, marketers can use real-time behaviour data to personalise every email for every customer.

So get Mailchimp and turn your customers into customers.

Hi, thanks for having me.

So you recently went on an adventure to see a place in New York that very few people get to see.

It's called a dark store?

Yeah, we know what a store store is, right? Like you walk by one on the street.

You know what that is. That's a store.

Sure.

A dark store is the same concept.

You walk by one on the street, but you can't actually go into it inside.

There's like a little warehouse and it is a place that operates and functions like a store.

It's just not open to customers. There's not like a cashier.

There aren't any of the things that you associate with the store at the very front of it.

You could live right next door. You could live above this building.

You could live, you know, on the same block, but you wouldn't go in.

You'd actually have to go on your phone, download an app.
