Note this option requires a developer.
We offer a number of integrations for you to add and request, but if you use an ESP we do not support, you can build your own.
Create a Custom Callback
1) Open the campaign you'd like to manage entries for. Select Integrations and choose Integrate Custom Script.
This can be done in your Brand Settings.
2) Provide a URL in the Callback URL field and we will make a POST to it every 20 minute with whatever entries joined in that period. Test the URL with the Test button.
3) Specify the pace at which you'll receive the emails. The limit is currently at 1k emails per hour.
