Is Your Team Wasting Hours on Email Busywork?
📥 Manual Download Hell
Your team spends 2-4 hours daily downloading attachments, renaming files, and organizing folders. That’s 10-20 hours per week on mindless busywork.
⏰ After-Hours Delays
Critical documents sit in inboxes overnight. Invoice processing, order fulfillment, and compliance workflows grind to a halt when employees go home.
❌ Human Error & Lost Files
Missed attachments, incorrect file names, and lost documents create compliance issues, late fees, and angry customers.
🔒 Cloud Vendor Lock-In
Cloud automation tools force your data through external servers, create compliance headaches, and charge per-task fees that spiral out of control.
ZenParse Email Extractor
Email Extractor is a Windows service that continuously monitors your Microsoft 365 mailboxes, intelligently extracts documents based on your rules, and organizes them for downstream processing—all without cloud dependencies or vendor lock-in.
How It Works (3-Step Process)
Step 1: Connect Your Mailboxes
Securely authenticate Microsoft 365 accounts using Microsoft’s device code flow. Add unlimited mailboxes in minutes.
Step 2: Create Smart Queries
Define extraction rules: filter by sender, subject, attachment type, date range, or body content. Use dynamic variables to automatically rename and organize files.
Step 3: Schedule & Automate
Set CRON-based schedules to run queries every minute, hour, day, or week. Your documents flow into your systems 24/7—even when you’re logged off.
Everything You Need for Email Document Automation

Built for Teams That Receive Business Documents via Email
Accounting & Finance
The Problem: Finance teams receive 100+ vendor invoices daily. Manually downloading and organizing PDFs takes 3+ hours.
The Solution: Email Extractor automatically pulls invoices from specific vendors, renames them with vendor name + date, and saves to your accounting system’s import folder.
Time Saved: 15 hours/week
ROI: 60x ($1,500 value vs $19 cost)
Mortgage & Real Estate
The Problem: Investors send loan bids via email (no API). Processors waste 90+ minutes daily downloading bid sheets, causing delays.
The Solution: Auto-extract bid attachments from investor emails and route to loan pricing system for instant comparison.
Result: Process bids in <5 minutes vs 90 minutes
Revenue Impact: Capture 15-20 additional time-sensitive bids/month = $50K+ annually
Logistics & Supply Chain
The Problem: Carriers email 200+ proof-of-delivery (POD) documents daily. Manual downloads take 4 hours and create compliance risks.
The Solution: Automatically extract PODs from carrier emails, organize by customer/shipment ID, feed to customer portal automation.
Compliance: Avoid 5-10 chargebacks/month
Savings: $3K-5K monthly
Legal Services
The Problem: Court filing confirmations, client documents, and discovery files arrive via email. Manual organization is error-prone.
The Solution: Extract documents by case number, client name, or filing type. Auto-organize into matter management folders.
Benefit: Audit trail for compliance, searchable document organization
Insurance
The Problem: Claims documents, policy applications, and medical records flood adjuster inboxes. Processing delays cost money.
The Solution: Auto-route claims documents to case folders, extract policy apps to underwriting queue, organize medical records by claim number.
Benefit: Faster claims processing, reduced errors, better customer experience
Healthcare Administration
The Problem: Patient referrals, insurance authorizations, and lab results arrive via email. Manual intake slows patient care.
The Solution: Extract referral PDFs to patient folders, route insurance auths to billing system, organize lab results by patient ID.
Compliance: HIPAA-compliant on-premise processing
Benefit: Faster patient care, reduced admin burden
