Service emails keep the product working — verification codes, receipts, confirmations. These are part of using Congruo and can't be switched off.
Product emails are built from your own results and activity — your personalised insights, changes at your verified company, and periodic score summaries. You can set how often these come — real-time, weekly, or monthly — through the preference centre link at the bottom of each email. Because they're part of the service you signed up to, they can be set to a lighter frequency but not switched off entirely.
Marketing emails — product news, new features, and our newsletter — only ever come if you've opted in, and you can unsubscribe from these at any time using the link in any of them, or through the preference centre link at the bottom of the email.
The preference centre is where you manage all of this in one place. There's a link in the footer of every emails we send (except for Service emails as we explained before).
