Alternatively Amazon could send a followup email. This way the sequence of events is preserved and not dependent on the sender.

I currently use email as a immutable list of events that have occurred in my life but with this I can no longer continue to do so.

So just use a client that doesn't support dynamic email, or disable the feature in clients that do.
