For each domain, it uses Tomba to find email addresses, filters the results for higher-quality contacts, saves those contacts to an enrichment sheet, and then marks the domain as completed before continuing the loop.\n\n### Setup steps\n\n- Configure the Schedule Trigger with the desired run frequency.\n- Connect Google Sheets credentials and select the sheet/range that contains pending domains.\n- Configure the Tomba credentials and domain lookup settings for finding emails.\n- Set the filtering criteria in the code node, such as confidence score, email type, or required fields.\n- Configure the enrichment Google Sheet destination and the status update fields used to mark each domain as done.\n\n### Customization\n\nAdjust the code filter to change what qualifies as a high-quality email, and update the Google Sheets mappings to match your domain, contact, enrichment, and status columns."
