We identify users using a couple of methods. It always depends on your account configuration (settings you can change) but also on the instance/agency configuration you inherit.
The most important are:
- subscribing to newsletter on your website, either in one of the forms you already have or using our email collectors.
- filling a form where email or phone information is mandatory
- people who clicked on the links in the emails we send and landed on your website
- other url tracking params that have identifiable data and are configured for this scope.
