About the CSV export
Six columns
Date, From, To, Subject, SizeBytes, Attachments — one row per message, in the order
the messages appear in the mailbox. UTF-8 with a BOM, so Excel opens it correctly.
Filter first, export second
Type in the search box to narrow the list (e.g. one sender or a keyword) — the CSV follows the filtered list, so you export exactly what you see.
Metadata only
The CSV contains headers and metadata, not message bodies. Need the full text on paper? That's what the PDF export (one-time, from $9.99) is for.
Simple pricing
CSV export is free, forever. PDF export licenses are one-time: $9.99 for 90 days or $19.99 forever.

Frequently asked questions
Is the CSV export really free?
Yes — unlimited rows, no account, no watermark, no daily cap. The paid license is only for the merged PDF export (full message bodies in one document).
Does the CSV include message bodies?
No. It carries metadata only: date, sender, recipients, subject, size in bytes, and attachment names. That's deliberate — it stays compact, opens instantly in Excel, and is exactly what inventories and review workflows need.
How do I open the CSV in Excel or Google Sheets?
Excel: double-click the file (the UTF-8 BOM makes Excel read international characters correctly), or Data → From Text/CSV. Google Sheets: File → Import → Upload.
Is my mailbox uploaded anywhere?
No. Indexing and CSV generation run entirely in your browser. Check the Network tab in your browser's developer tools — no file content ever goes over the wire.
