Why Save Emails to Google Drive?
Google Drive provides reliable, searchable storage for email archives. Here's why professionals use Drive for email backup:
The Problem
Email providers have storage limits and deleted emails are often gone forever. Critical business communications live in fragile email systems that can be accidentally deleted or lost during account transitions. Compliance requirements demand email retention, but manually downloading and organizing emails is impractical at scale. Team members need access to historical communications, but forwarding or CC'ing everyone clutters inboxes.
The Solution
When you automatically save emails to Google Drive, each message becomes a permanent file with full content and attachments preserved. Your email archive lives in Google Drive's reliable storage with 15GB free (or more with paid plans). You get instant search across all archived emails using Drive's search functionality, and complete email preservation with all headers, formatting, and attachments intact. Drive's familiar interface makes finding old emails simple, and you can share specific folders with team members while keeping everything centrally organized.
What You Need
You'll need a Google account with access to Google Drive and an email account (Gmail, Outlook, or any provider that supports forwarding). The setup process is quick, and we'll create the Drive folder automatically for you.
Step 1: Connect Google Account to Mailsink
Here's where we set up automated email archiving:
- Sign up at mailsink.app.
- Click "Connect Google" from the dashboard.
- Authorize Mailsink to access Google Drive.
- Google will show you the permissions Mailsink needs.
- Mailsink requests access to create and write files to Drive.
- Click "Allow" to authorize the connection.
- Your Google account is now connected and ready to receive emails.
This authorization lets Mailsink create a dedicated folder in your Google Drive and save email files automatically.
Step 2: Create Your Google Drive Email Inbox
Now we'll create the inbox that archives emails to Drive:
- Navigate to the Inboxes tab in Mailsink.
- Click "Create Inbox" and select the Google Drive option.
- Choose your connected Google account from the dropdown.
- Name your email folder (optional):
- Default:
Mailsink - [inbox-key] - Example:
Mailsink - Client EmailsorEmail Archive
- Default:
- Click "Create Inbox".
- Mailsink creates a new folder in your Google Drive root.
- Each incoming email will be saved as a
.emlfile in this folder. - Files are named with date, time, and subject for easy identification.
- You receive a unique inbox address like
abc123@in.mailsink.app.
- Copy the generated inbox address — you'll use this for email forwarding.
- Open your new Drive folder from the provided link to see the structure.
The folder is now ready to receive emails. Each forwarded message will appear as a separate .eml file that you can open with email clients or view in Drive.
Step 3: Forward Emails to Google Drive
Now configure your email provider to archive to Google Drive.
From Gmail
Set up Gmail filters to archive specific emails:
- Open Gmail → Click the search bar → "Show search options" (filter icon).
- Set filter criteria:
- From: Specific senders (e.g.,
contracts@client.com) - To: Specific recipients (e.g.,
legal@yourcompany.com) - Subject: Keywords to match (e.g., "invoice" or "contract")
- Has attachment: Check this if you only want emails with files
- From: Specific senders (e.g.,
- Click "Create filter".
- Check "Forward it to" → Enter your Mailsink address.
- Optional: Add labels or mark as read.
- Click "Create filter".
Example filters:
- Archive all emails from
legal@company.com→ Legal email archive - Archive emails with "contract" in subject → Contract archive
- Archive emails with attachments to
documents@company.com→ Document archive

From Outlook
Create Outlook forwarding rules for archiving:
- Open Outlook settings (gear icon → "View all Outlook settings").
- Navigate to "Mail" → "Rules".
- Click "Add new rule".
- Name your rule (e.g., "Archive to Drive").
- Set conditions:
- From specific senders
- Contains specific words in subject
- Has attachments
- Sent to specific addresses
- Action: "Forward to" → Enter your Mailsink address.
- Save rule.
More details: Check our Outlook integration guide for screenshots and troubleshooting.
From Any Email Provider
Most email services support forwarding. Look for:
- "Forwarding" or "Auto-forward" in email settings
- "Rules", "Filters", or "Automation" sections
- "Forward messages to" options
Simply set the forward address to your Mailsink inbox address.
Step 4: Test Your Email Archive
Verify everything works correctly:
- Send a test email to the address you configured forwarding for.
- Include a subject line and some body text.
- Optional: Add an attachment to test full archiving.
- Wait a few moments for processing.
- Open your Google Drive folder and refresh if needed.
- Verify your email appears as a
.emlfile:- ✅ Filename includes date, time, and subject
- ✅ File type is
.eml(email message format) - ✅ You can preview the email in Drive
- ✅ Attachments are preserved within the email file
- Double-click the file to preview or download.
Troubleshooting:
- Email not appearing? Check your forwarding rule is active and the Mailsink address is correct.
- Can't open .eml file? Download it and open with your email client (Gmail, Outlook, Apple Mail, Thunderbird).
- Missing attachment? Attachments are embedded in the
.emlfile—open it with an email client to access them. - Connection error? Verify your Google connection is active in the Mailsink dashboard.
Understanding .EML Files
What is an .EML File?
.eml is the standard email message format (RFC 822). It's a text file containing the complete email including:
- All email headers (From, To, Date, Subject, Message-ID, etc.)
- Full email body (both plain text and HTML versions)
- All attachments (encoded within the file)
- Original formatting and structure
How to Open .EML Files
Google Drive Preview: Click the file in Drive to preview (basic view).
Download and Open with Email Client:
- Gmail: Upload the
.emlfile as an attachment, then click it to view. - Outlook: Double-click the downloaded
.emlfile to open in Outlook. - Apple Mail: Double-click on Mac to open in Mail app.
- Thunderbird: File → Open Saved Message.
Convert to PDF: Use online converters or email clients to export as PDF for easier sharing.
Searching .EML Files in Drive
Google Drive indexes the content of .eml files:
- Search by subject: Type keywords from the email subject
- Search by sender: Use "from:sender@domain.com" in Drive search
- Search by content: Drive can search the text within email bodies
- Search by date: Use Drive's date filters

// Find emails with specific subject keywords
subject:"contract" OR subject:"agreement"
// Find emails in date range
after:2026-01-01 before:2026-12-31
// Find emails with attachments over certain size
size:>5MB
// Combine criteria
type:eml from:client@company.com after:2026-01-01
Automation with Google Apps Script
For advanced users, automate further:
- Auto-organize emails into date-based folders

Sharing and Permissions
Control access to your email archive:
- View only: Team members can read archived emails
