When a customer visits your site, we set a unique cookie on their device. This is used to track all of their interactions.
When our script has been customised, we collect email addresses from any field where it can be entered on your site such as:
Registration pages
Login pages
Newsletter sign-up pages
It will then be associated with that cookie ID. We don't even need to wait for the form with the email address field to be submitted to pick it up.
Once the email address is associated with the cookie, subsequent visits don't require the our system to wait for the email address entered, the customer is automatically identified from the cookie and the system can trigger emails to them.
Additionally, with certain Email Service Providers (ESP), our system can be set up to connect to their system, which can be used to turn the unique ID added to the links in your email campaigns into an email address, without waiting for the customer to identify it.
ESP providers
If the ESP you use doesn't allow this, you can either include the email address on the links in your bulk campaigns using the e parameter, or import a file of IDs and email addresses, then include the ID on the links using the eid parameter. If either of these are supplied, our system identifies the visitor without needing to scrape their email address.
