Include uploaded files in e-mail template macro

Include uploaded files in e-mail template macro

Is it possible to create a macro that, upon selection, will send an e-mail template to a customer, which will include a pre-written message as well as one or two attachments. The attachments will be different for each customer, so the macro would have to include the e-mails uploaded to that particular contacts page.

Is this possible through a macro or perhaps other means such as a creator app?

Advice is appreciated, thanks.
