AT Internet natively distinguishes 2 sources types:
- organic sources (by default, without tracking variable)
- marketing sources (tracking to implement)
Email marketing corresponds to e-mailings campaigns which generate traffic on the website.
As the main difference, we note that the email marketing is a marketing traffic source and webmails is an organic traffic source.
We define portal sites as an option which has to be activated (it's not a standard source). It gives access to all sites of the contract that generated traffic on the analysed site.
