Most lead sources will be able to send generated leads to an email address, or email endpoint. This is the easiest way to get leads into goBluebird the moment they are generated.
To find your email endpoint open the left sidebar, and select Integrations from the Configuration section. Towards the top of the page you will see your Email Endpoints.
Be careful not to reveal this information, as emails sent to this email address will be parsed and sent into your company as new leads.
