Send your document via email as a PDF attachment

DocHub offers several ways to share your PDF documents including two options to send an email with your PDF attached. Your DocHub account's Primary email address will be set as the Reply-To address for both methods, so if the person replies, their message will go directly to your email address.


  1. Click on the Share or Send Dochub_UI_-_Share_or_Send_button.png button in the upper right corner while viewing your document.
  2. Choose 'Send as Attachment' in the Share dialog that opens.
  3. Fill out the To: field and use commas to separate multiple email address.
  4. Customize the Subject & Body fields using the Edit button (if desired).
  5. Check any boxes to Flatten or Certify.
  6. Click Send.

  • Certify document - Embeds an Adobe compliant digital signature that certifies the creator of any signatures in your document and assures the document has not been altered after signing.
