Ability for a client to download an uploaded file straight from the email notification. Including a security disclaimer would be recommended, but for attachments that don't contain sensitive information, this would save the client time and won't require login to download.
File Attachment is currently available in Estimates, Invoices, Proposals, Documents, Work Requests, Email Marketing Campaigns, Drip Sequences & Email Cannons.
But, this request seems to be related more to when you are uploading files in the Files module.
Please help us clarify EXACTLY where and in what scenarios you want to see the File(s) attached/linked in the email notification sent to the end user.
Please be specific because we are preparing to deliver this feature. We want to make what you ask for!
