✉️ What is Email Verification?

Email Verification is a lightweight access control feature that sends a 6-digit one-time passcode to your selected email address before allowing users to view your shared PDF file. It's perfect for:

Client document sharing
Internal team reports
Private proposal reviews
Secure ticket or file delivery

✅ How It Works

Enable "Email Verification" when configuring your file on MaiPDF
Enter up to 50 authorized email addresses, separated by commas
When someone opens the PDF link:
- They are prompted to enter their email
- A masked preview shows which emails are allowed (e.g., jo**@domain.com)
- They instantly receive a code in their inbox
Once the code is verified, access is granted

Step 5: Monitor Verification Logs

MaiPDF provides detailed logs of email verification attempts. Use these logs to monitor who accessed the document and ensure that only authorized users are viewing your files.

Updated MaiPDF protection path

Use Online Cloud Sharing for speed; use MaiPDF App DRM when screenshots, forwarding, or device access matter

SendPDFOnline pages now describe MaiPDF as a two-level product family: Online Cloud Sharing creates quick browser links and QR codes, while the MaiPDF App creates protected .maipdf packages for sensitive PDFs that need App DRM controls.

Fast cloud link

Upload a PDF, share a browser link or QR code, and keep read code / modify code management.

Protected .maipdf file

Package the PDF in the MaiPDF App with local encryption, license rules, expiry, open limits, and revoke control.

App-only protections

Use protected viewer, device binding, screenshot-aware controls, watermark trace, and license management where supported.

No web page can fully stop screenshots. MaiPDF App DRM is positioned as the stronger path: reduce casual copying, bind access to identity/devices, revoke licenses, and trace leaks with visible watermark information.
