I'd like to be able to track visitors from transactional emails in Google Analytics, but I'm not sure what values to use for the UTM tags.
utm_medium
should obviously be "email", but what about utm_source
and utm_campaign
?
Is there any good practice for that? The only think I'd like is be consistent.
By "transactional emails" I mean emails like:
- You've got a new private message
- Confirm your email. etc.
