Email newsletters are highly personal: Landing directly in our inboxes, bidding us good morning and good night, crafted to sound more like a knowledgeable friend than a news organization.

Crain Communications is doubling down on email as a means of amplifying its reach. The Detroit-based publishing group is best known for its city-centered business newspapers, such as Crain’s New York Business and Crain’s Chicago Business, and its trade periodicals, including Advertising Age and Autoweek. It already sends out breaking news and digest newsletters associated with those publications.

To serve the communities where Crain’s doesn’t currently run a dedicated magazine, newspaper, or website, the company has launched nine city-based morning email newsletters that draw from a mix of original content, stories from Crain’s publications, and business- and tech-related stories from other news outlets. Currently, readers in Atlanta, Boston, Dallas, Houston, Los Angeles, Philadelphia, San Francisco, Silicon Valley, and Washington, D.C., can sign up for the free curated emails tailored to their cities (there are also breaking news email options for each location). Emails go out to subscribers around 8 a.m. each weekday in their time zones.

Sounds pretty standard — but behind the well-oiled machine are dedicated editors in each location, as well as content management and customization software that can pull together engagement metrics to individually shape each email that goes out to a reader. Crain hired Sean Flanagan, who’s worked at Maxim, Reader’s Digest, and National Geographic, as publisher of the new newsletters brand.

Editors in each location sort through hundreds of relevant business-related news stories, writing introductory text and adding punchier headlines as needed. Subscribers can choose the topics that interest them, from about a dozen options. The newsletters’ content may change from one day to the next, based on which stories in the previous day’s newsletters readers are clicking on.

Crain’s integrated several key pieces of customized technology from different partners to build out their new email products, chief digital officer Brian Reilly told me. Editors use a content aggregation platform that serves as a sort of CMS to source stories and to extensively tag this incoming content. An algorithm-based “intelligence engine” then helps match story tags to various attributes of readers signed up in the Crain’s database, and feeds the “right” stories into various email templates that go out to readers.

“The structure of the newsletter is based on who you are and where you are,” Rob Elder, Crain’s director of digital product development and strategy, said. “There’s no set structure. There could be several national news items that everyone gets, and the ‘Up Late’ segment at the end, but other than that, we rely on the intelligence engine to build newsletters for every reader.” (Up Late is a screenshot and tease text to a scene from a talk show that aired the previous night, continuing the trend of newsletters throwing in lighter, “dessert” items to close off an email.)

I tried to get a sense of the personalization by signing myself up for all nine offerings, and the only major piece I noticed show up in all the newsletters in a single day was “Zuck defends non-foundation route to divest billions,” a story from Fortune.

As organizations from BuzzFeed to Vox to The New York Times are learning, newsletters are a great vehicles for experimentation and direct feedback.

Newsletters “allow us a great opportunity to measure right out of the gate how things are working, to get a lot of feedback very quickly,” said KC Crain, executive vice president and director of corporate operations.

The newsletters are ad-supported, and draw from an existing Crain’s audience base (an email about signing up for the new city-based newsletters went out to people who’d previously offered up their emails to Crain’s in some capacity). It’s too early to share details like subscriber numbers or open rates, KC Crain said, but the numbers they’re seeing have “far exceeded expectations.”

“The initial business model was based on our current audience,” Crain said, “but we’re excited now to watch how many new people sign up.”

As for the ads in the emails, “one thing we didn’t have before, when we sold ads, was the scale. Now our sales guys are able to have whole new conversations.”

Because the initial audience base for the newsletters started with people who were already familiar with the Crain’s brand, there were a few immediate areas that could be personalized: the person’s location, the Crain’s vertical they were interested in, and the categories of interest they ticked when they signed up for a newsletter (or newsletters), according to Reilly.

“Over time, we’ll observe engagement, and tweak the algorithm,” he said. “If one day you click on an automotive story, you’re not going to see a feed full of automative stories; the algorithm makes gradual and incremental adjustments.”

As the audience base grows, “we’ll look at all factors of engagement.”

Elder and Crain are confident these newsletters will differentiate themselves in the crowded fields they’re entering, even with competition pressing in on a national and local level. Just in Boston, for instance, there are already The Boston Globe (as well as BetaBoston and Stat), the Boston Herald, the Boston Business Journal, CommonWealth magazine, and a handful of other online publications that touch on business, finance, and tech in the city. They didn’t divulge specific strategies for each city but emphasized that Crain’s did extensive research in each of its launch markets, and similar newsletter products can be created for new cities beyond the first nine. The brand’s focus on anticipating what readers will want is another differentiator.

“When a story or topic gains traction, we put more resources behind it, like any news staff would,” Elder said. The editors, he added, not only search for the top business stories in each beat, but also try to spot news that may trend. “The idea here is we give people news before they think they need it.”

“While each place is different, I’ve noticed a gap between traditional business coverage and startup and tech stories,” Elder said. There seems to be a wide gulf between those communities — and there’s an opportunity for us to bring them together and cover them in context.”

“We’re doing more original content and we’ve been able to do it faster than we thought,” he added. “We’re finding a need and a hunger for it in these markets, and we’re primarily focused on building those brands.”
