Interesting to see two major news outlets — The Verge and Wired — both announce major newsletter strategies nearly simultaneously. I suspect both are motivated by the hope that email will be "stickier" than the (declining) direct traffic to news websites.
"The Verge Launches New Site Features Aimed at Deepening Audience Engagement and Announces New Editorial Newsletters": https://www.theverge.com/press-room/710921/verge-site-features-launch-newsletters
"A New Era for WIRED—That Starts With You": https://www.wired.com/story/a-new-era-for-wired-that-starts-with-you/
The Verge cites the desire to "deepen[] its direct relationship with readers". Wired writes "The platforms on which outlets like WIRED used to connect with readers, listeners, and viewers are failing in real time", saying they wish to "connect our humans to all of you humans".
I don't need every source of everything I'm tangentially interested in hounding me for attention on a daily basis.
