Who is a subscriber?
Every user that clicks on ‘Allow’ on the opt-in of your website and subscribes to receive notifications is assigned a unique Subscriber ID. You can read more about determining the Subscriber ID of a visitor here.
Can I export my list of subscribers?
Yes, if you are on a paid VWO Engage plan, you can export your list of subscribers anytime. You can find out how to export it here.
VWO Engage’s FCM keys are used by all VWO Engage's customers that have not created their own FCM keys yet. Also, FCM keys are associated with an Encryption key, one cannot be used without the other.
Hence, to avoid notifications being sent to all subscribers of VWO Engage customers and to maintain their privacy and security, we cannot share the Encryption Key.
