Customising headers would also be useful so you can distinguish Channel on the Elastic Email side which would allow you to report by domain - important if you are managing multiple Discourse sites with one Elastic Email account.

It’s a bit annoying Elastic Email can’t distinguish source domain out of the box, like SparkPost can, but SparkPost is no longer an option now they’ve upped prices.
