Can I track emails from vendor subdomains like mail.supplier.com?

Yes, use 'Text Contains' with just the root domain (supplier.com) in your filter. This catches emails from any subdomain at that company.

What happens if I accidentally delete rows from the tracking spreadsheet?

Zapier doesn't sync deletions back to Gmail, so deleted audit trail entries are permanently lost. Consider making a backup copy of your tracking sheet weekly.

Can I track emails sent TO vendors, not just FROM them?

No, Gmail's 'New Email' trigger only fires on incoming mail. For sent email tracking, you'd need Gmail's 'New Sent Email' trigger as a separate Zap.

Why don't some vendor emails appear even though the domain matches?

Gmail's API can miss emails during high server load, and some automated vendor emails go to Promotions or Spam tabs. Check your Gmail filters and tab settings.

Can I add the email body content to my tracking sheet?

Yes, map Gmail's 'Body Plain' field to a column, but email bodies can be very long and may hit Zapier's 6MB data limits on email threads with attachments.

Real-World Example

💡

A 12-person manufacturing startup uses this to track all communication from their 8 key suppliers for compliance audits. Before automation, the procurement manager manually forwarded vendor emails to a shared folder and forgot to log about 30% of communications. Now they have complete audit trails when supplier disputes arise over delivery schedules or specification changes.

Configure Email Filter Settings

Set up filters to only capture emails from your vendor domains. This prevents the Zap from firing on every single email in your inbox.

1In the 'Label/Mailbox' dropdown, select 'INBOX'
2Leave 'From' field empty for now (we'll filter later)
3Set 'To' to your email address if needed
4Click 'Continue' to save trigger settings

✓ What you should see: The trigger configuration panel should show your selected inbox settings.

Add Filter for Vendor Domains

Create a filter to only process emails from your vendor domains. This step prevents non-vendor emails from cluttering your tracking sheet.

1Click the '+' button between trigger and action
2Search for 'Filter by Zapier' and select it
3Choose 'Only continue if' condition
4Set field to 'From Email' from Gmail data

✓ What you should see: The filter step should be inserted with Gmail's 'From Email' field selected.

⚠

Common mistake — Use 'From Email' not 'From Name' — vendors can change display names but email domains stay consistent

Filter > Conditions

Configure Domain Filtering Logic

Set up the filter conditions to match your vendor domains. You can check for multiple domains using 'contains' logic for each vendor.

1Set condition to 'Text Contains'
2Enter your first vendor domain (e.g., 'vendorname.com')
3Click 'Add OR condition' for additional vendors
4Add each vendor domain as a separate condition
5Click 'Continue' to save filter

✓ What you should see: Your filter should show multiple OR conditions, each checking for a different vendor domain.

⚠

Common mistake — Use just the domain part (acme.com) not full email addresses — this catches emails from any person at that company

Action > Google Sheets > Create Spreadsheet Row

Add Google Sheets Action

Configure Google Sheets as your action app to log the vendor email data. This creates the audit trail in your spreadsheet.

1Click the '+' button after your filter
2Search for 'Google Sheets' and select it
3Choose 'Create Spreadsheet Row' as the action
4Click 'Continue' to proceed

✓ What you should see: Google Sheets should appear as your action step with 'Create Spreadsheet Row' selected.

Action > Google Sheets > Account

Connect Google Sheets Account

Authenticate your Google account to allow Zapier to write data to your spreadsheets. This enables the automatic logging functionality.

1Click 'Sign in to Google Sheets'
2Select your Google account
3Click 'Allow' to grant spreadsheet permissions
4Verify the connection shows as active

✓ What you should see: Your Google account should appear connected with access to your spreadsheets.

⚠

Common mistake — Use the same Google account that owns your tracking spreadsheet — shared spreadsheets can have permission issues

Action > Google Sheets > Spreadsheet & Worksheet

Select Target Spreadsheet

Choose the specific spreadsheet and worksheet where vendor emails will be logged. Create column headers if this is a new tracking sheet.

1Select your tracking spreadsheet from the dropdown
2Choose the specific worksheet tab
3If headers don't exist, add them: Date, Sender, Subject, Domain
4Click 'Continue' to proceed with mapping

✓ What you should see: Your selected spreadsheet and worksheet should appear in the configuration panel.

⚠

Common mistake — Don't select a spreadsheet with existing data unless column headers match your mapping — Zapier will append to the first empty row

Action > Google Sheets > Field Mapping

Map Email Data to Spreadsheet Columns

Configure which Gmail data goes into each spreadsheet column. This creates the structured audit log with consistent formatting.

1Map 'Date' column to Gmail 'Date' field
2Map 'Sender' column to Gmail 'From Email' field
3Map 'Subject' column to Gmail 'Subject' field
4Add 'Domain' column mapped to Gmail 'From Email' (you'll extract domain later)

✓ What you should see: Each spreadsheet column should show the corresponding Gmail data field mapped to it.

⚠

Common mistake — Don't map the email body unless needed — Gmail bodies can be huge and hit Zapier's data limits on long email threads

Test the Complete Workflow

Run a full test to verify emails are properly filtered and logged to your spreadsheet with correct data formatting.

1Click 'Test step' on the Google Sheets action
2Review the test data being sent to your sheet
3Check that only vendor emails passed the filter
4Verify all mapped fields contain correct data
5Click 'Continue' if the test succeeds

✓ What you should see: You should see a new row added to your spreadsheet with the test email data properly formatted.

⚠

Common mistake — The test uses your sample email from step 4 — if that wasn't from a vendor domain, the filter will block it and the test will show 'Filtered out'

Publish > Zap Settings

Publish and Monitor the Zap

Activate your vendor email tracking and set up monitoring to ensure it continues working properly over time.

1Click 'Publish Zap' to make it live
2Give your Zap a descriptive name like 'Vendor Email Tracker'
3Turn on email notifications for errors
4Check the Zap history after 24 hours to verify it's working

✓ What you should see: Your Zap should show as 'On' with a green status indicator in your dashboard.

⚠

Common mistake — Gmail can take 1-15 minutes to trigger depending on your plan — don't panic if vendor emails don't appear immediately

Scaling Beyond 300+ vendor emails/month+ Records

If your volume exceeds 300+ vendor emails/month records, apply these adjustments.

Switch to Webhook Triggers

Gmail webhooks fire instantly vs polling every 2-15 minutes. Set up Gmail push notifications to a Zapier webhook URL to reduce delays and task usage.

Add Deduplication Logic

High email volume increases duplicate delivery chances. Add a Google Sheets lookup step to check Message ID before creating new rows, or use Zapier's built-in deduplication filters on paid plans.

Batch Process with Delay

Add a 2-minute delay step before writing to Sheets if multiple vendor emails arrive simultaneously. This prevents Google Sheets API rate limiting during email bursts.

Analysis

VerdictWhy Zapier for this workflow

Use Zapier for this if you need a simple audit trail without coding and your vendor volume stays under 500 emails per month. The Gmail trigger fires within 2-15 minutes of new emails, and the visual filter builder makes domain matching straightforward for non-technical users. Skip Zapier if you need real-time logging under 30 seconds — go with Make's webhook triggers instead.

Cost

This workflow burns 1 task per vendor email logged. At 200 vendor emails monthly, that's 200 tasks total, fitting Zapier's free 100-task tier if you stay selective with domains. The $19.99 Starter plan handles up to 750 tasks. Make costs $9/month for the same volume but requires more setup complexity. N8n is free self-hosted but needs server management skills.

Tradeoffs

Make handles Gmail's API pagination better — if you're importing historical emails in bulk, Make processes batches of 100+ emails without choking. N8n gives you custom SQL queries to deduplicate emails at the database level, while Zapier's deduplication requires paid plans. But Zapier's Gmail integration is more reliable day-to-day and recovers better from temporary API errors that happen during Google maintenance windows.

Gmail rate limits hit at 250 requests per user per second, but Zapier's polling approach rarely triggers this unless you have massive email volume. The bigger issue: Gmail's search API sometimes misses emails during high-traffic periods, especially around business hours when servers are loaded. Vendor emails from shared inboxes (like [email protected]) may not trigger consistently if multiple team members access the same Gmail account through different apps.

Ideas for what to build next

→
Add Slack Notifications for Urgent Vendors — Create a second Zap that posts to Slack when high-priority vendors email you, using the same Gmail trigger with different domain filters.
→
Set Up Automated Vendor Response Tracking — Build a follow-up Zap that monitors your sent emails to vendors and logs your responses in a separate 'Outbound Communications' sheet for complete audit trails.
→
Create Monthly Vendor Communication Reports — Use Google Sheets' pivot tables or connect to Google Data Studio to automatically generate monthly reports showing communication frequency by vendor domain.
