Troubleshooting Could Not Add Lead to Campaign Error Message

I cannot understand why does it show "Could not add lead to campaign" even after everything is set right? I even enabled "Allow Duplicate leads across campaigns"

There could be several reasons why you're seeing the "Could not add lead to campaign" error even with duplicates allowed: 1. The lead might be blocked in your account - blocked leads won't be processed regardless of duplicate settings. 2. You may have reached your account's lead limit - no new leads can be added until your limits are increased or adjusted. If you want to prevent this issue in the future, you can: ** Use a Lookup action in Clay to check if a lead already exists in your campaign ** Create a column to flag duplicates by matching key fields * Set up conditional formulas to prevent the integration from running for existing contacts
