Rather than relying on a pii file to supply an email, generate it.
An email is often used as a unique identifier for a user. For apps where it is required that you submit an email it won't work very well to have a static email. Therefore it's better to generated an email for the bot run.
You might be required to click on a link that has arrived to the email address that you submitted. This link will effectively confirm that you are registered. Miriam mentioned that we should do this, so to achieve this we can use the api that mailinator.com provides to check the email address that we provided.
