You can't merge your Pinterest accounts. If you have more than one account you can either keep both accounts, or choose one to keep and deactivate any others.
Each email address can only be connected to one Pinterest account at a time, and deactivating an account won't free up the email address for use on another account. If you want to free up the email address on an account, close the account or change the email address connected to your account in your settings. Once you change the email address, you can deactivate the account and use your original email address on another account.
If you can't access your original account, you can still search for it on Pinterest and save Pins from your original account to your new account. There's no way to transfer or move multiple Pins between accounts at once, but you can save each Pin one by one.
