The ePrivacy Regulation (PECR) is set to particularise GDPR for electronic communications and is focused only on electronics — devices, processing techniques, storage, browsers etc.
It is the successor to the current ePrivacy Directive, known as the ‘Cookie Law’ because it has governed the statement frequently seen on Europe-based sites that declares users agree to the use of cookies if they agree to use the site.
According to the e-Privacy rules of email marketing (Reg.22), marketing emails & texts should not be sent to individuals without specific consent, although there are limited exceptions for existing customers.
