Yes. eMail is still a favourite topic of mine. Years later, it’s still the one single medium, that allows communicating across organisational boundaries. It’s still the one medium that allows to reach out to random people, e.g. for marketing. Despite the difficulties GDPR introduced for marketeers in 2018, driving a lot of marketing to proprietary, US-American platforms. Inside corporate, it’s still the one single medium that allows to make sure your manager is informed with communication between otherwise colleagues. (About the good climate, obviously.)
