“One of the main ways I keep up to date on marketing nowadays is newsletters. Here are my favorites: […] Experiment Nation – newsletter by Rommil Santiago covering the experimentation space. Links to articles, events, memes etc.” – Alex Birkett, Co-founder of Omniscient Digital
“I used to be a newsletter junkie. I’ve since unsubscribed from most of them but there are three that I will probably never turn my back on for as long as they exist. These are […] Rommil Santiago’s Experiment Nation newsletter.” – Luka Nikoli?, Web Optimization Specialist at Avast
