> Disengagement gets its own sequence. You haven't opened this in a while, then maybe your interests have changed and here are others, then you've been unsubscribed. They also survey the disengaged about why

> The BBC built Upbeat for news avoiders, now nearly 39% of people against 29% eight years ago. Seven hundred words of positive stories, deliberately withholding enough to send readers on to the site

> David Topping's rules from the Toronto Star: pick one word your newsletter promises, tell readers why to click rather than just linking the headline, and make the call to action a big stupid button

> The Toronto Star found in 2021 that digital subscribers receiving at least one newsletter were half as likely to cancel. Its flagship morning newsletter now comes with every new subscription

> It ran for years on a manual query, holding lists and a Google Doc of exclusions before being rebuilt as a webhook. Only then could it extend to sister titles and registered users
