If this issue occurs, please check the Email Template used to send the Document.
Click Settings
Under Templates and Files, click Email Templates
Click on the Document Link
If a Document opens, this means the direct link to the Document was added to the template, causing it to be sent every time the template is used.
To solve this, remove the link and replace it with the HTML URL Merge Field from the Document dropdown.
If this does not resolve the issue, please reach out to our friendly Customer Support Team in the in-app chat or via support@eventtemple.com
