Before campaigns, communications, and analytics become meaningful, you need usable audience data inside TruAgents. The current app supports both file-based import and connected data sources. That makes this step less about one upload button and more about choosing the right ingestion path for your team. ## Who this is for * New customers setting up their first audience * Operators responsible for data import quality * Technical admins connecting external contact systems ## Where to find it in the app * **Contacts** * **Contacts → Data Sources** * **Contacts → Segments** TruAgents contacts overview page with import actions and empty-state guidance The main **Contacts** view gives you a quick read on whether anything has been imported yet and points you toward the next import action. ## Recommended first-run path ### Option 1: Start with a file import Use this when you need the fastest path to a working dataset. A simple import is usually the best way to validate field mappings, contact quality, and downstream campaign behavior. ### Option 2: Connect a data source Use this when contact data already lives in another system and you want ongoing sync behavior instead of one-time manual import. ## Supported source types visible in the current app * CSV or file import * HubSpot * Mailchimp * Salesforce * SendGrid * SFTP-based import flows ## What success looks like * [ ] A data source exists or a file import completed successfully. * [ ] Imported records appear under **Contacts**. * [ ] The team understands which fields are being used for email, phone, name, and timezone data. * [ ] Segments can now be created or evaluated against the imported audience. ## Common things to validate early * Whether the source has the right email and phone fields populated * Whether timezone information exists or needs a default strategy * Whether duplicate handling and contact quality rules need follow-up decisions * Whether the imported audience is large enough and clean enough for the first campaign ## Related pages * [Import and sync data sources](/workflows/import-and-sync-data-sources) * [Build and manage segments](/workflows/build-and-manage-segments) * [Contact import field mapping](/reference/contact-import-field-mapping)
