A email thread, to me, is much preferable to any IM, unless participants knows to send those IMs in a thread as well.

All the context are in there in the rawest of forms, you a run through them with your eyeballs or have your tools do the summarisation there and then. Most of the IMs I received didn't even quote the original message they were responding to, and I end up spending time jumping up and down the channel or group to get the whole context. Not to mention folks sending me link to a slack, which, depending on the mood of the almighty slack god, can or cannot be opened in the app / current slack session.

But you do you. :)
