Players are opted in to marketing from your club by default. They can opt out at any time in the app under Settings → Marketing preferences, separately for each club and company they are linked to.
Where players change it
In the app: Settings → Marketing preferences.
In a White Label app, players can also opt out per club when they sign up.
What respects a player's choice
Announcement push notifications and emails.
Automation push notifications and emails.
What doesn't
A push notification you send from the Player List with Action → Send push notification. It goes to every selected player.
Service emails, such as booking confirmations, receipts and cancellations.
In-app announcements on your club's home screen.
Where you can see it
Export your player list. The Email opt-in column shows each player's choice. See "How do I export my player list?".
Integrations such as Mailchimp and HubSpot also receive each player's choice.
Good to know
You can't change a player's marketing choice for them. Ask the player to update it in the app.
