If you try to register for Coinmama and receive an error message that the user already exists, it is probably for one of the following reasons:
You've already registered using this email address. Try logging in instead and see if that solves the issue.
You've previously had an account with Coinmama. If you're trying to reopen a previously closed Coinmama account, you'll receive an error message. Please [contact] (https://support.coinmama.com/hc/en-us/requests/new) our support team for next steps.
You already have an account under a different email address. Coinmama does not permit multiple or duplicate accounts. If we detect that you're registering under multiple email addresses, we will have to block all but your original account.
