📥 Mail Attachment Downloader PRO

Route Gmail emails or attachments straight to your network folder — no Apps Script required.

Gmail has no native way to drop emails or attachments onto a local network folder or NAS. Mail Attachment Downloader PRO connects directly to Gmail over secure OAuth, watches every account you configure, filters exactly the emails you want, and saves the emails or attachments (or the whole email) straight onto your network storage — no coding, no browser extension, no cloud middleman.

Why teams automate this

Gmail wasn't built to talk to your file server

Google Drive sync, Apps Script, and browser extensions can each do a piece of this — but none of them cleanly and reliably write straight to a local network folder or NAS on their own.

📬

Monitor multiple Gmail accounts with one rule set

Handling invoices@yourcompany.com on Google Workspace and a personal Gmail alias? You don't need separate scripts for each.

  • Connect Gmail (personal or Google Workspace) via secure OAuth — no app password needed
  • A global rule runs against all connected accounts by default
  • Isolate a rule to a single account by adding an Account filter
🎯

Advanced filtering by sender or subject

Isolate exactly the emails you care about before anything gets saved.

  • Filter by Email Subject — search terms like Payments or Invoices
  • Plain text does a substring match; quoted terms support logical operators
  • Example: 'Payments' OR 'Invoices' for powerful, precise rules
💾

Save exactly where files belong

The Save phase gives full control over the destination path for network or NAS storage.

  • Point directly at a local network folder or network-attached storage path
  • Use field tokens to build dynamic folder structures automatically
  • Works whether the destination is mapped or a raw UNC path
✉️

Archive the whole email, not just the file

Some downstream systems need the full message context, not just the attachment.

  • Check Save as .eml to archive the entire email into the same target folder
  • Keeps sender, subject, and body together with the attachment for OCR or compliance tools
  • Feeds cleanly into document archiving systems and ERP software downstream
What the rule looks like

Filter once, save everywhere it needs to go

Two Gmail accounts, two destinations, zero manual effort.

// Rule: Invoices - Shared Network Folder
Account: invoices@yourcompany.com (Gmail)
Filter: Email Subject contains 'Payments' OR 'Invoices'
Save to: \\NAS01\Shared\Accounting\Invoices\{DATE}\
☑ Save as .eml
// Rule: Sales Orders - Shared Network Folder
Account: sales@gmail.com
Filter: Email Subject contains 'Order' OR 'PO'
Save to: \\NAS01\Shared\Sales\Orders\{DATE}\
How it flows

Set it up once, let it run 24/7

Configure the rule wizard, test it, and walk away.

1

Connect your Gmail accounts

Secure OAuth sign-in — personal Gmail or Google Workspace

2

Add a filter

By account, sender, or subject — with logical operators if needed

3

Set the destination

Point the Save phase at your network folder or NAS path

4

Runs unattended

As a Windows Service, 24/7, feeding your downstream systems

Gmail can throttle a connection if too many requests come through in a short window — the program is built with this in mind, scheduling retrievals sensibly so your rules keep running reliably instead of hitting rate limits.
How it stacks up

PRO vs. the usual ways people save Gmail attachments to a network folder

Most approaches route your data through a browser extension, a cloud automation platform, or require you to write your own Apps Script. PRO connects directly and keeps everything local.
