Add File Downloads to HubSpot Marketing Emails Without Killing Deliverability

March 25, 2026

Why You Can't Just Attach Files to Marketing Emails

Here's the thing: adding files to marketing emails isn't as straightforward as it is with one-to-one sales emails. We've all learned the hard way that bulk attachments are a fast track to the spam folder, and that's not where you want your carefully crafted campaigns landing.

The good news? HubSpot's got a solution that's both simple and effective. Instead of traditional attachments, you'll use a button linked to a file download. This keeps your deliverability clean and your humans happy.

How to Add a File to Your Marketing Email

Let's walk through this step by step so you can get your file downloads set up without any hiccups.

Step 1: Navigate to Your Marketing Email

  1. Log into HubSpot and click on the Marketing section in the left sidebar
  2. Select Email from the menu
  3. Click on the draft email you want to edit (or create a new one)

Step 2: Add a Button to Your Email

Open your email editor and add a button where you want the file download to live. This could be anywhere in your email that makes sense for your content. Maybe it's a call-to-action at the bottom, or perhaps it's near relevant content in the middle of your message.

Step 3: Edit Your Button Text

Double-click your button to edit the text. Make it clear what humans are downloading. Something like "Download Our Guide," "Get the PDF," or "Access Your Resource" works perfectly. Be specific about what they're getting, not vague.

Here's where the magic happens:

  1. Click on the "Link To" option in your button settings
  2. Choose "File Download" instead of a regular link
  3. You'll have two options here: upload a new file or browse existing files from your HubSpot file manager
  4. Select your file (PDF, document, spreadsheet, whatever you're sharing)

Step 5: Preview and Send

Before you hit send, preview your email using the preview button in the top right corner. Click on your button to make sure the file downloads correctly. Once you're happy with how it looks, you're ready to send your email with confidence knowing your deliverability won't take a hit.

The Bottom Line

Adding files to your HubSpot marketing emails doesn't require attachments or complicated workarounds. A simple button with a file download link keeps your emails clean, your inbox reputation strong, and your humans getting exactly what they came for. It's a win across the board.

The execution is where it counts. Go out there and start building better marketing emails with file downloads today.
