# Overdue follow-up nudge
# Sends a templated email to every lead whose follow-up date has passed. Runs a dry run first and refuses to send unless you pass --send, because the failure mode here is emailing your whole pipeline by accident.
#
# Category : Operations
# Safety   : WRITES DATA, read before running
# Uses     : leads list, leads send-email, email-templates list
# Returns  : A merged dry-run preview, then the sends once you confirm.
#
# Requires the SendSquared CLI and jq:
#   curl -fsSL https://cli.sendsquared.com/install.sh | bash
#   sendsquared auth login
#
# Free to use and adapt. https://sendsquared.com/cli/scripts/#followup-nudge

# Usage: ./followup-nudge.sh <templateId> [--send]
# Without --send this only previews. That default is deliberate.
