The good news is that with our system you can connect with your favorite email marketing app (like Mailchimp, Aweber, Emma, etc) and use their familiar interface. With our system you can send your customers' information automatically to your favorite app, using Zapier.
You can check the list of supported systems here.
There are two ways to capture and send your customers automatically:
Using the New Customer Trigger: in this case all users will be automatically sent
Using the New Subscriber Trigger: only those customers are sent who subscribed to your newsletter - for this you need to turn on this field under Manage > Locations > click on name > Data Capture.
Webhooks are also available if you need more control.
