There are a few possible reasons why Smartlead might show leads as added but they don't appear in the campaign:
1. Duplicate prevention: If "Allow Duplicates" is turned off, duplicate leads won't be added or updated.
2. Blocked leads: Leads already blocked in your account won't be processed.
3. Lead limit: If you've reached your account's lead limit, new leads can't be added until limits are adjusted.
To troubleshoot:
** Check your Smartlead settings for duplicate handling
** Verify if any leads are blocked
* Confirm your account's lead limit
