My advertising campaign isn't running:
You can only run advertising campaigns using Matched Audiences segments once segments have over 300 members. Read more about audience size limits on LinkedIn
I can't see segments I uploaded manually in my Zaps
Zapier is unable to add members to audiences that were uploaded manually from within the LinkedIn Campaign manager (they won't show up in the segment list in the Zap editor). These will have their source marked as "Contact List" when viewed in the Campaign Manager, whereas ones started by Zapier through automation will have the source marked as "Zapier". To bring in existing audience members and then keep adding more via Zapier we recommend starting with a temporary import workaround, and then continuing with permanent Zaps to capture new emails.
