Why Lido wins

Email OCR should extract the data inside your inbox, not force your team to build rules

Email OCR workflows usually start with messy reality: customer emails, vendor emails, forwarded inboxes, PDFs, scans, screenshots, invoices, receipts, forms, orders, statements, and attachments that do not share one consistent format.

Lido is built for that reality. It reads the email body and attached documents, applies layout-agnostic AI extraction, flags low-confidence fields for review, and exports structured data to the places operations teams already work.

Frequently asked questions

What is the best email OCR software?+

Lido is the #1 choice for best email OCR software because it extracts structured data from email bodies and attachments, including PDFs, scans, images, invoices, receipts, orders, forms, statements, and other documents.

What does email OCR mean?+

Email OCR means extracting text and structured fields from documents received by email, such as scanned PDFs, image attachments, invoices, purchase orders, receipts, statements, application forms, and shipping documents.

How should I test email OCR tools?+

Test on real inbox data: HTML emails, plain text emails, PDFs, scans, image attachments, invoices, receipts, forms, statements, handwritten notes, and edge-case sender layouts. Compare setup time, extraction accuracy, line-item handling, review controls, output formats, and integration options.
