HubSpot CMS Guide: How to link to a document on your website
If you've created a landing page offering a downloadable asset, you'll want to provide this asset on a Thank You page or in an automatic follow-up email. Here are instructions for how to add a document to a website page (via a hyperlink) (and you can follow Step #2 when setting up the follow-up email).
1. Edit the module in which you want to link to a document
Click the orange Edit button above the module with the text you'd like to link to a document.
2. Add an attachment
Highlight the bit of text you'd like to turn into the hyperlink leading to the document. Then click the Attach icon in the toolbar.
In the layover that appears, click Upload a new document.
Click Choose File and find the document on your hard drive. Then click Upload new document.
On the next screen, simply click Insert.
Remember to save your module when you're done!
