If you have a list with twitter handles or emails, you can upload it through the sources part of the dashboard. The process is very simple as you are required to upload the list as a .TXT file, or in the case of an existing Twitter list, you need to add the twitter URL where the platform will link it.
In the case of the email list, the platform may not recognise all of the emails as Twitter users, because these emails are not the ones that are linked to their Twitter accounts, however by uploading them here you are asking for these emails to be converted to Twitter handles, and you can read the privacy agreement provided on the platform when you click on the + sign under Email contacts, and follow instructions. Alternatively, you can email an Excel file/request to Privacy@audiense.com to match emails to handles. This service is offered by our partner Full Contact.
