You can automatically sync your customer's from Uscreen into a Mailchimp audience. Mailchimp will then allow you to send beautiful email campaigns to your customers and track detailed delivery and open statistics.
Before you begin, please ensure the audience you wish to sync to does not have any required fields, other than email.
In Mailchimp, click your Profile in the top right and select Extras > API Keys. Click Create a Key and then you'll want to copy the API Key that's created.
Now let's add the API Key into Uscreen.
Navigate to Settings > Integrations and click Connect on the Mailchimp integration. Paste in your API key and then you'll be directed to select the List ID(Audience) you want to sync to. Once done, new customers will sync to your Mailchimp Audience.
