Add Listener First and Last Name via Zapier
You can include listener's names when they sign up for your Hello Audio private podcast feed using a Zapier step "Add/Edit Listener Metadata in Hello Audio".
This step would be #3 in a Zap automation. #1 is the trigger when they sign up. #2 adds them to the feed. And this #3 updates the listener to include their name details.
Grab their name info from the trigger of the Zap. You can then use personalization of your feeds to include their first name in feed or episode titles, for example. You can read more about that feature here.
