There are two types of emails that we send to customers : 1) marketing emails and 2) product / service / transaction emails.
1. For marketing emails, each email has an unsubscribe link at the bottom of the email which you can click on to opt out of receiving further emails. After clicking this, you will no longer receive marketing emails.
2. For product / service / transaction emails, these are important for us to be able to keep you informed about what is going on in your account, and there is therefore no opt-out option. The only way to stop these is by closing your account.
