Creating a new Pinterest account with the same email address is not possible. Each Pinterest account requires a unique email address during the sign-up process. Pinterest uses email addresses as a unique identifier for each account.
If you already have an existing Pinterest account associated with your desired email address and want to create a new account, you'll need to use a different email address to sign up for the new account. This can be an email address from another provider or you can create a new email address specifically for your new Pinterest account.
If you no longer have access to the email address associated with your existing Pinterest account, you can try recovering or resetting the password for that account using the account recovery options provided by Pinterest. If you encounter any difficulties, you can reach out to Pinterest support for further assistance.
