You can add attachments to emails using the Attachment field in the Email Builder. This field allows you to place an attachment within an email body, which gives you the opportunity to track contact engagement with your attachment(s) and learn over time which attachments have the most benefit to your contacts.
To add an Attachment, click Add Content, hover over Attachment, and drag the Attachment field into a Column or Row of your email.
Customizing The Attachment Field
To select the attachment you'd like to add, click Choose File.
Select a file from your File Library, or click Upload a File to select a file from your computer.
Once a file is selected, click Save Selection.
To add multiple files, you'll need to add multiple Attachment fields. Your attachment will show up within your email wherever you drag it.
