About this workflow

SPAM MANAGER FOR LEAD GENERATION Automatically identifies and manages spam replies from your outreach inbox; such as “Delivery failed” or “There was a problem with your delivery” which comes from "mailer-daemon@googlemail.com" for Gmail. This is to remove these messages to keep your email lists clean and improve domain reputation. --- 🎯 Who it’s for This workflow is designed for lead generation managers, outreach specialists, and freelancers who send cold or automated emails at scale. It helps you automatically filter and manage bounce or spam responses without manually combing through your inbox, ensuring your sender domain stays healthy and your lead lists remain accurate. --- ⚙️ How it works 1. Trigger: Watches your Gmail inbox for replies from system senders like mailer-daemon@googlemail.com. 2. Extract Email: Pulls out the email address from each bounce or spam message. 3. Merge: Compares the extracted address with your main lead sheet. 4. Update Sheet: - If the email exists in your main sheet, it updates that record’s SPAM field to "YES". - Otherwise, it adds the address to a dedicated Unsubscribe or Bad Emails table. 5. Mark as Read: Tags and marks the email as processed in Gmail for better visibility. --- 🧩 Requirements To run this workflow, you’ll need: - Gmail Credentials → For reading and tagging emails. - NocoDB API Token → For reading and updating your lead list and spam records.(You can use Sheets, Airtable or any other DB you use). Both can be securely added through the n8n Credentials Manager. --- 🧠 How to Customize - Sender Filter: Change the Gmail Trigger to include other mailer domains or error messages. - Data Storage: Replace NocoDB with Google Sheets or Airtable. - Tagging: Adjust or remove the Gmail label used for spam-marked messages. - Message Matching: Edit the MERGE code node to fit your column names (e.g., Email, Address, etc.). --- 💡 Why this workflow matters By automating spam and bounce handling, you: - Keep your lead database clean and current - Reduce bounce rates and spam flags - Improve your email deliverability and sender score - Save time spent manually checking failed emails --- 🪄 Quick Setup Tips - Add your Gmail and DB credentials under the Credentials tab. - Update the DB project and table IDs in relevant nodes. - Test with a few known bounce messages to verify connection and matching. - Optional: Add a “SPAM” tag in Gmail for quick inbox filtering. "UNSUBSCRIBE" is used in this workflow. --- 🧾 Workflow Info Workflow Name: SPAM MANAGER FOR LEAD GENERATION Category: Email & Data Hygiene Version: 1.0 Created for: Outreach and CRM Automation --- Author: Itunu Portfolio: Itunu’s Automation Portfolio
