Sending Attachments from a Sheet as an Attachment instead of a Link

We have a use case where we need to send attachments from a sheet to individuals outside of our company. The employees at this company are not allowed to click the link within the email to download the attachment. Is there any way to send an attachment from a sheet and have it received as an actual attachment instead of a link? Or does anyone have other workarounds they have come across for sending attachments to individuals outside of your organization when those individuals can't click the link to download the attachment?
