Hello @JeniferR6 ,
We are a permission-based email service, which means you need to provide your own contacts, or utilize various list growth tools to start bringing in new contacts. Some list growth tools include integrations developed by 3rd party services, if you're needing to bring over contacts from your database in another system. For list growth tools developed by us, such as sign up forms or integrations we've developed in-house, we can provide support for those as needed.
