When creating your lease on Zillow Rental Manager, the email address you are logged in with will automatically be added to the lease, and it will not be possible to edit.
This prevents landlords from entering an email that does not have an associated Zillow account, which would render them unable to access their lease for signing after their tenants signed.
If you already have an account under the email you are attempting to use, please log in to your preferred account to proceed.
If you do not already have an account, but still need to change the email address, you can do so in the settings for your Zillow account. Use this link to access your settings: https://www.zillow.com/myzillow/Account.htm
