Sending a document pack? Use a data room instead

Put all files in one HelpRange data room: guests log in with an e-mail code, sign your NDA, and you see who opened which document – with uploads and AI answers from the documents.

Merging PDFs is handy for application packs, due diligence bundles and board packs – one file instead of ten attachments.
