I built a 6-workflow GoHighLevel system that runs off one tag: NGMI. Any disqualification trigger (bad-fit form response, spam Do Not Call list match, manually disqualified status) adds the NGMI tag. From there, six workflows fire in sequence. Opportunities get deleted across every pipeline. Active workflows halt. DND turns on. The contact is blocked from re-entry. If someone manually removes the NGMI tag later, the chain reverses: DND off, contact eligible again.
