  • Check that your API key has the necessary permissions
  • For ActiveCampaign: ensure the API URL matches your account
  • For OAuth integrations: try disconnecting and reconnecting

Subscribers not appearing in my CRM

  • Check that you selected the correct list
  • Some CRMs have a delay before new contacts appear
  • Verify the entry method is set to “Mandatory” if you want all users added
