How to email your PDF as attachment via DocHub or Gmail

Last Updated: Nov 30, 2017 02:34PM CST

DocHub offers several different ways to share your PDF documents which includes two options for sending as an email attachment. You can either let DocHub send the email for you which is sent from or you can send from your own Gmail where DocHub composes a draft for you with the PDF attached. Your email address will be set as the Reply-To for both methods, so if any of the recipients reply to your email with the PDF attachment, their message will go directly to your email address. 
(Sent from with your email address as the Reply-To)

1.) Click on the Share or Send  button in the upper right corner while viewing your document.
2.) Choose to 'Send as Attachment' in the Share dialog that opens. 
3.) Fill out the To: field in the compose window and use commas to separate multiple email address. The Subject & Body fields will already be filled in with our default text, but you can still customize it, if you'd like by clicking on the Edit button next to them. By default, the Subject is simply named after the filename of your PDF.
4.) Click on Send via at the bottom. 

Before choosing to Send, you have the option to edit the default text in the Subject and Body of the email for a personal touch, and if you have DocHub Pro and are sending a PDF with form fields, you'll also see two options for flattening the PDF before sending. The option to 'Flatten the PDF' locks all of the form fields and embeds them into the PDF as permanent text. Then, 'Rasterize pages' will convert every page of your PDF into a flat image.  

Your email address will be set as the reply-to address so that when the recipient responds, it'll come to you, and you'll be BCC'd on the email by default. For the To: field, if you are authenticated with Google and want to enable auto-complete or type ahead, you can click on the Google Contacts button to link up your saved contacts and any emails you've corresponded with in Gmail for faster input). 

The size limit for emailing documents in DocHub is currently 10 MB which includes both the size of the attachment plus the email itself, and with DocHub Pro, you can send up to 250 documents in any rolling 24 hour period to up to 20 recipients per email, and free accounts can send up to 3 emails a day to up to 3 recipients per email. 

To view a list of all of the documents you've emailed including the recipient's email address and customize your email footer that gets inserted at the bottom of all emails you send via DocHub, you can go to


 (supports sending multiple PDF attachments in one email)

For Google authenticated DocHub accounts, you can also Send via Gmail where DocHub composes a new Gmail draft for you with your PDF attached and sets the Subject after the name of your document. Here's how:

1.) Click on the Share or Send  button in the upper right corner while viewing your document.
2.) Select 'Send as Attachment' in the Share dialog that opens. 
3.) Confirm by clicking on Open as draft in Gmail at the bottom of the window.

If your pop-up blocker is disabled, you'll be automatically taken to your new draft in Gmail where you just need to add recipients and send, but for most people whose pop-up blocker is turned on, you'll need to navigate manually to your Gmail Drafts folder to finish and send it. 

This options supports sending more than one PDF in a single email which you can do from your DocHub Dashboard in the Documents or Templates sections by selecting the PDFs you want to attach and then click on the envelope icon at the top. DocHub will then compose a Gmail draft for you with all of the PDFs you selected attached which you can finish and send from within your Gmail
