We recommend to first read this overview of how email address are captured by Barilliance 

The GDPR is an EU privacy law that took effect on May 25, 2018. It regulates the treatment and use of personal data belonging to EU citizens.

Under the GDPR it is not allowed to capture personal data unless the visitor gives explicit consent for it. Consent is usually granted by checking a certain checkbox on the page. The checkbox description will usually state how the email address will be used or link to a privacy policy with those details (please consult with your legal department for exact requirements, Barilliance cannot give legal advice on this matter).

Barilliance will monitor the relevant checkboxes and only if they are checked will proceed to capture emails from input boxes.

For it to be recorded and for transparency we’ll ask you to specify to us exactly which input forms and checkboxes we should monitor (please contact us to receive the form to fill for this information)

An important point to understand is that under GDPR it is not allowed to capture the email address before consent is given, even if we do not plan to send any emails!  What this effectively means is that the consent checkbox must be on the same page as the email input box or on a previous page. If the consent is given in a later pageview, while we will have the consent, we will no longer have access to the email input box and cannot capture it. If that is the case for your website, we can add a checkbox for you that will serve for that purpose.

The triggered email booster must be generated with the GDPR option for the emails to be captured from it.
