Lena Dunham’s feminist newsletter Lenny Letter and its website are shutting down.

The newsletter had interviewed Hillary Clinton. It also ran articles by Jennifer Lawrence and Michelle Obama, as well as covering style, politics, and gender issues.

The newsletter had grown to over 500,000 subscribers, but reports said it had struggled to secure ad revenue.

In its final email on Friday, it wrote: “Please, continue to push forward the voices that need a platform, the untold stories that deserve to be heard, the diversity that the publishing industry claims to value but has never mastered.”

Lenny Letter, Lena Dunham’s feminist newsletter which ran articles by Jennifer Lawrence and Michelle Obama, is shutting down.

Dunham, who founded the newsletter in 2015, intended for it “make the world better for women and the people who love them,” according to the email the newsletter sent to new subscribers.

But in its email to subscribers on Friday, it said “today because this is Lenny’s final chapter.”

The final issue encouraged subscribers to be politically active, to canvass and vote in the run up to the middterm elections.

It also urged subscribers: “Please, continue to push forward the voices that need a platform, the untold stories that deserve to be heard, the diversity that the publishing industry claims to value but has never mastered.”

The newsletter said “there’s no one reason for our closure,” but a report in Digiday said that the newsletter had always struggled to gain ad support. It signed a deal with Condé Nast to handle ads for the site in October. Condé Nast did not respond to requests for comment from the Post and Digiday.

The newsletter grew to over 500,000 subscribers, according to Digiday, but its growth on social media had slowed. Nearly half of subscribers were still opening the emails in July 2017, sources told the New York Post.

Lenny Letter Michelle Obama wrote for Lenny Letter in March 2016.

The newsletter is sent by email twice a week and covers topics including feminism, style, politics, health.

“I think our ideal audience is anyone who considers themselves to be a progressive feminist who wants to live an inspired life,”Dunham told Business Insider in 2015.

“Our goal isn’t for you to read it at lunch. Our goal is for you to have a relationship with it and talk to your friends about it.”

As well as discussions of topics like birth control, anxiety, gender issues, and activism, the newsletter includes interviews with “powerful female figures who get us excited.”

Lenny Letter Lena Dunham interviewed Hillary Clinton for Lenny Letter’s first issue in September 2015.

It published pieces with women like actress Gillian Jacobs, New York Timesbest-selling novelist Jessica Knoll, and feminist thinker and activist Gloria Steinem.

Jennifer Lawrence wrote for Lenny about the Hollywood gender pay gap, and the newsletter interviewed Hillary Clinton when she was campaigning in the 2016 presidential election.

“In the three years since we began, the Internet has opened up for underrepresented writers in ways we wouldn’t have predicted or believed from our 2015 bunker,” Friday’s newletter said. “It was an honour to be part of that brigade, and we can’t wait to see how those who forged that path keep holding space after Lenny is gone.”

Dunham, best known as the writer, star, and creator of HBO show “Girls,” founded the newsletter with production partner Jenni Konner. It is unclear whether the sites’ podcasts – “Women of the Hour” and “Lenny Says” – will continue.
