Guides for lead managers

The rules that matter to anyone who collects leads and passes them on to partners, explained with an exact reference to the source.

The guides cover consent to marketing and to passing data on to third parties, tracking pixels in emails, artificial intelligence applied to leads, and earning from leads instead of advertising. They are signed by the Markmatix editorial team: each one cites the article or decision with a link to the official source, shows the date of its last update and is published only after review. They explain the rules in general and are not legal advice.
