1. Your account
You must register with a real, working email address that can receive mail. Disposable and temporary email domains are blocked, because invoices, activation confirmations and password resets are all delivered by email.
You are responsible for activity under your account and for keeping your password secure. One person or organisation per account; do not share credentials.
Every new account receives 20 free credits as a trial. Creating multiple accounts to collect the free credit bonus repeatedly is not allowed and may result in suspension.
