"email is clunky and awkward"
With email I have a local archive of all manner of things - business transactions, private and my long-closed freelancing business, family stuff, family history stuff, local history stuff, everything I've been interested in and felt the need to keep going back for years.
To some extent it is clunky and awkward because even with some rules-based stuff, because no email client I've seen has been designed to do half what an efficient office filing system would do but it's a different league to depending on somebody else's computer to do it for me.
Messages are not always ephemeral.
