Automate Candidate Email SLA with Gmail & Slack Alerts

Never let another candidate email slip through the cracks. This n8n workflow automatically monitors your Gmail inbox for candidate communications and sends instant Slack alerts when your team hasn't responded within your SLA timeframe, ensuring every potential hire receives timely follow-up.

What this workflow does

This automated Gmail and Slack integration runs on a scheduled basis (every 5 minutes or your preferred interval) to maintain consistent candidate communication standards. The workflow fetches emails from the last 24 hours, filters candidate messages based on sender domain and label categories, then performs intelligent thread analysis to detect whether your recruiters have replied within the conversation.

When an unanswered candidate email is identified, the system automatically connects to your Slack workspace, retrieves channel members, and intelligently selects an available team member—prioritizing active users when possible, or selecting randomly if needed. The designated recruiter receives an immediate Slack alert with details about the SLA breach, enabling quick response and follow-up.

Use cases

• Recruitment agencies: Maintain competitive response times and prevent candidate drop-off due to delayed communication
• HR departments: Ensure consistent candidate experience across multiple recruiters and hiring managers
• Talent acquisition teams: Monitor email SLA compliance and automatically distribute workload among available team members
• Staffing firms: Track response times and maintain service level agreements with both candidates and clients
