Description

Gmail Candidate Email SLA Monitoring & Slack Alert Workflow

This workflow automatically monitors candidate emails received in the last 24 hours and checks whether a recruiter has replied within the same thread. If no reply is found, it flags it as an SLA breach and sends a Slack alert to an available team member (active if possible, otherwise random). This helps ensure timely communication with candidates.

Quick Implementation Steps

1. Login to your n8n account.
2. Set up the Scheduler node (e.g., every 5 minutes or as preferred).
3. Connect your Gmail account and fetch emails from the last 24 hours.
4. Filter candidate emails using sender domain and label/category.
5. Use thread analysis to detect if a reply exists.
6. Connect Slack and fetch channel members.
7. Check presence and select an active (or random) user.
8. Send alert message via Slack using user ID.
9. Activate the workflow.

What It Does

This workflow continuously monitors incoming emails from candidates and ensures that no message goes unanswered. It focuses specifically on emails received within the last 24 hours and identifies conversations that have not received a reply from the recruiter.

Once emails are fetched, the workflow filters relevant candidate communications based on sender domain and label/category. It then retrieves the full email thread and analyzes whether any reply has been sent from the recruiter’s side. If no reply exists in the thread, it is marked as an SLA breach.

To ensure quick action, the workflow integrates with Slack. It checks the availability of team members and intelligently selects an active user. If no one is active, it assigns the alert to a random team member, ensuring accountability and timely follow-up.

Who It’s For

• Recruitment teams handling candidate communication
• HR departments managing high volumes of emails
• Hiring managers who want to improve response times
• Operations teams focused on SLA compliance
• Startups and agencies managing multiple candidate pipelines

Requirements

To use this workflow, you need:

• An active n8n account
• Gmail account connected via n8n
• Slack workspace access
• Slack API credentials configured in n8n
• A Slack channel with team members
• Basic understanding of email threads and Slack user IDs

How It Works & Set Up

Setup Instructions

1. Scheduler Configuration

   • Set the trigger interval (default: every 5 minutes)
   • Users can adjust this based on their needs

2. Gmail Integration

   • Connect your Gmail account
   • Use “Get Many Messages” node
   • Configure to fetch emails from the last 24 hours

3. Filter Candidate Emails

   • Apply filtering logic using:
     • Sender domain
     • Email label/category

4. Thread Retrieval

   • Use thread ID to fetch full conversation
   • Ensure all messages in the thread are available

5. Reply Detection

   • Analyze messages in the thread
   • Check if any message has SENT label
   • If yes → mark hasReplied = true
   • If no → mark as SLA breach

6. Slack Integration

   • Fetch members from selected channel
   • Retrieve presence status for each member

7. User Selection Logic

   • If any user is active → select active user
   • Else → randomly select a user

8. Send Slack Alert

   • Send message using selected user ID
   • Include candidate email and thread details

9. Activate Workflow

   • Test all nodes
   • Enable workflow for automation

How To Customize Nodes

• Scheduler Node
  • Adjust frequency (e.g., every 10 mins, hourly)
