## Introduction
For growing startups and agile sales teams, maintaining a well-structured and organized CRM database is critical. One common challenge in lead management is grouping contacts by their associated company domains to form ‘accounts’—a feature Salesforce offers with its Lead to Account Matching capability. However, Salesforce licensing costs and complexity can be prohibitive for small to mid-size teams.
In this guide, we will demonstrate how to replicate the core functionality of Lead to Account Matching using n8n, a powerful open-source workflow automation tool. By automating contact grouping based on email domains, your sales and marketing teams can benefit from higher data quality and better segmentation without the expensive price tag.
This tutorial is designed for startup CTOs, automation engineers, and operations specialists looking to optimize CRM workflows by integrating common SaaS tools like Google Sheets (as a data source), Gmail, and Slack for notifications.

## Use Case
**Problem:**
Sales teams often need to consolidate individual leads or contacts under the parent account based on their email domain to have a complete view of interactions and opportunities. Without automated lead-to-account matching, the data becomes scattered, leading to inefficiencies and lost revenue opportunities.
**Who benefits:**
– Sales Operations Specialists managing CRM data quality
– Automation Engineers building cost-effective pipelines
– Founders and CTOs aiming to reduce CRM licensing costs
—
## Tools and Integrations
– **n8n:** Core automation platform
– **Google Sheets:** Source of contacts/leads data
– **Slack:** Notification channel for matched groups
– **Gmail:** Optional notification or follow-up automation
*Note*: You can integrate any CRM or database instead of Google Sheets. Google Sheets is used here for demonstration.

## How the Workflow Works
1. **Trigger**
– Manually triggered or scheduled workflow (e.g., daily at midnight) to scan new or modified leads in Google Sheets.
2. **Fetch Leads**
– Read leads data from Google Sheets, each with at least an ‘Email’ and ‘Name’ field.
3. **Data Processing – Extract Domains**
– Parse each contact’s email address to extract the domain part.
4. **Group Contacts by Domain**
– Aggregate contacts whose emails share the same domain, thus forming an “account.”
5. **Check Existing Accounts**
– Check if the account/domain grouping already exists in an accounts list (another Google Sheet or database).
6. **Update/Create Account Entries**
– Append or create new account records associating contacts accordingly.
7. **Notify Sales Team**
– Send a Slack message summarizing newly formed accounts or updated groups.
8. **Optional Follow-Up**
– Send customized Gmail notifications to sales reps about updated accounts.

## Step-by-Step Technical Tutorial
### Step 1: Setup the Trigger
– Add a **Cron node** configured to run at your preferred schedule or a **Webhook node** if triggered on demand.
### Step 2: Retrieve Leads from Google Sheets
– Configure a **Google Sheets node** to read rows from your leads sheet.
– Scope: Read all leads or filter based on a last updated timestamp for efficiency.
– Required fields: Name, Email
### Step 3: Extract Email Domains
– Use a **Function node** with JavaScript code to iterate over each lead and extract the domain portion:
“`javascript
return items.map(item => {
const email = item.json.Email;
const domain = email.substring(email.lastIndexOf(“@”) + 1).toLowerCase();
item.json.domain = domain;
return item;
});
“`
### Step 4: Group Leads by Domain
– Add another **Function node** to group contacts by `domain`:
“`javascript
const grouped = {};
items.forEach(item => {
const domain = item.json.domain;
if (!grouped[domain]) grouped[domain] = [];
grouped[domain].push(item.json);
});
return Object.entries(grouped).map(([domain, contacts]) => ({ json: { domain, contacts } }));
“`
### Step 5: Check Existing Accounts
– Add a **Google Sheets node** configured to read your accounts sheet, which stores existing domain groups.
– Use a **Function node** to compare existing accounts and identify new domains.
### Step 6: Update or Create Account Records
– For new domain groups, use the **Google Sheets node** in append mode to add new account entries.
– For existing groups, update the contacts field or relevant metadata accordingly.
### Step 7: Notify via Slack
– Add a **Slack node** configured to post a message to your sales or operations channel.
– Format the message to include domain names and counts of contacts grouped.
### Step 8 (Optional): Gmail Notification
– Configure a **Gmail node** to send email notifications to sales managers or specific sales reps, including details of new or updated accounts.

## Common Errors and Robustness Tips
– **Invalid Email Formats:** Use regex or additional validation in the Function node to discard or flag malformed emails.
– **Large Datasets:** For large lead lists, consider paginating sheet reads, or integrate with a database for scalable querying.
– **API Rate Limits:** Respect Google Sheets and Slack API limits by batch processing or introducing delays.
– **Data Consistency:** Use unique IDs for accounts to avoid duplicates, and maintain timestamp fields to track updates.
– **Error Handling:** Employ the n8n error workflows feature to catch failed nodes and alert admins.
—
## Adapting and Scaling the Workflow
– **CRM Integration:** Replace Google Sheets with your actual CRM database or API, e.g., HubSpot or custom SQL.
– **Real-time Triggers:** Use webhook triggers or API calls from your lead capture forms to run the workflow instantly.
– **Additional Matching Logic:** Enhance grouping by including company name similarity or IP/domain validation services.
– **Bidirectional Sync:** Update the CRM accounts with matching information from n8n to keep both systems synchronized.

## Summary
By implementing this n8n workflow, startups can automate lead to account matching based on email domains—a fundamental CRM capability usually locked behind costly Salesforce licenses. This approach improves data quality and workflow automation at a fraction of the cost while leveraging flexible integrations like Google Sheets, Slack, and Gmail.
**Bonus Tip:** Schedule the workflow to run during off-business hours to minimize disruptions and integrate with a logging system (e.g., external database or Slack logs) for audit trails.
This automation not only saves licensing fees but empowers your sales operations with customizable, transparent control over key CRM processes.
