As the subject suggests, I'd like to be able to include a physical attachment in real-time (or outbound) email.
I do not just want to add a button/link for the recipient to download a file; I'd like them to have a permanent copy of that file in their email inbox.
Secondly, if I was able to extend it even further, and have a unique file per recipient (e.g. an invoice/receipt) then that would be useful.
Any thoughts on either of the above being achievable?
Thanks.
