01. Main Features
The SysCurve PST Email Address Extractor Tool swiftly and accurately harvests every unique sender and recipient address from Outlook PST files. Designed for both individual users and enterprises, it streamlines list building, data migration, compliance audits, and marketing workflows while preserving message integrity and eliminating duplicates.
High-Speed Scanning
The SysCurve PST Email Address Extractor races through small personal archives and multi-gigabyte enterprise mail stores alike, pinpointing every valid address in seconds. Its streamlined code reads PST indexes directly, minimizing disk thrash and maximizing throughput on standard hardware. Whether you need to extract email addresses from PST files for GDPR audits or fast contact consolidation, the program keeps wait times to a minimum. Even massive Outlook backups spanning years of correspondence are processed with the same smooth, consistent speed.
Eliminates Duplicate Addresses
Nothing ruins a mailing list faster than repeated contacts, so the Outlook email address extractor automatically filters duplicates in real time. Each address is normalized, compared, and stored only once, guaranteeing that your final CSV remains spotless. By delivering a pristine, duplicate-free list, the tool saves you the hassle of post-processing in spreadsheets or database scripts.
Preview PST
The PST Email Address Extractor lets you preview messages inside the software window. You can click any message to view its details, which is a convenient way to confirm you’re working on the correct PST file. This pre-flight check builds confidence and prevents accidental extraction from the wrong mailbox.
Selective Export
The SysCurve PST Email Address Extractor lets you tick only the folders that matter—Inbox, Sent Items, project sub-folders, or archives—so you extract email addresses from PST files with pinpoint accuracy rather than sweeping the entire mailbox. By ignoring irrelevant folders, the tool shortens processing time, keeps the output list tightly focused. This targeted Outlook PST email extraction feature is ideal for audits, department-level campaigns, or any situation where you need precise, folder-specific contact data without extra noise.
Multiple Export Options
With the help of the SysCurve PST Email Address Extractor, you can save addresses to CSV, JSON, XML, VCF, HTML, or plain TXT with a single click. This broad format support ensures seamless hand-off to SQL databases, email-marketing suites, data-analysis pipelines, and contact managers.
Preserves Data Integrity
The software opens every PST in strict read-only mode, guaranteeing the original mail store remains untouched throughout extraction. Internal checksums verify blocks as they’re read, protecting against corruption even if the PST is old or oversized. Because nothing is written back to the file, there's zero risk of damaging critical mail evidence or personal archives.
Support for Large PST Files
Built to tackle hefty PST archives—from modest 2 GB mail stores to massive 50 GB bundles—the Outlook Email Address Extractor keeps memory use in check and the interface responsive. It works in smart, bite-sized chunks that temper disk reads and RAM demand, so even sprawling corporate mailboxes can be analyzed and addresses exported on an ordinary workstation—no heavyweight server setup required.
User-Friendly Interface
The SysCurve Email Address Extractor features a clean, straightforward design. A ribbon-style layout guides you from file selection to export, while progress bars and status messages keep you informed at every stage.

Users report thousands of successful extractions without hangs or crashes, making the tool a trusted component of daily data-prep routines. You can count on consistent output even under heavy workloads.
