Slack User lookup from email?

[Iron-Bound]

Have alerts with actions assigned as email addresses currently, any way to do a lookup on the tool side to map email to slack users?

Could do a lookup in splunk but rather not have to maintain a CSV :)

Cheers, AB

We require Slack usernames match the account's usernames, so this hasn't come up for us.

Patches welcome to make this pluggable / add support for other mechanisms, though!
