For the past few weeks, Twitter has been encouraging creators to sign up for its subscription product which saw the replacing of credible blue verified ticks for paid-only verification. To be eligible for subscriptions, creators must subscribe to Twitter Blue at $8 a month or be part of a verified organisation, according to Twitter’s sign-up page.

Twitter’s director of product management overseeing subscriptions, Patrick Traughber, told employees on Thursday that Twitter would further promote subscription content on the platform, including by sending push notifications promoting the content and showing previews of tweets behind the paywall in the For You timeline, according to audio of a meeting reviewed by The Information. Traughber said his team is working to add three to four features a week to its creator subscription offering.

Since Musk took over, Twitter’s creator monetization efforts have focused heavily on paid subscriptions, especially after Twitter gutted its product team in late February. Earlier that month, Musk had said that Twitter would share revenue from ads in replies to creators who paid for Twitter Blue, but there’s no evidence that such a program has begun.

Twitter introduced subscriptions under the name “Super Follows” in February 2021, joining companies like Patreon, Substack and OnlyFans that allow users to pay creators directly for exclusive content. Since then, Meta Platforms and TikTok have started testing similar products.

As of Monday, Musk had 24,700 subscribers who paid him $4 a month for a total of six exclusive tweets to date, according to a screenshot he tweeted. That’s around 0.02% of his 136.4 million followers. Musk himself subscribes to accounts including those of Daniel Francis, who posed as a laid-off Twitter employee in November, and Tesla Owners Silicon Valley.

It was surprising the platform went ahead with it after the initial Twitter Blue rollout last November led to a surge in impersonations, including of major companies and Musk himself. More recently, on April 20, Twitter removed the blue checks from most users who had been verified under the old system—but it restored the checks to accounts with over a million followers and others who had criticised Twitter Blue; some celebrities complained that this made it appear they were paying for the product.

As of last weekend, independent researcher Travis Brown estimated that between 615,000 and 650,000 accounts had subscribed to Twitter Blue, although that likely included thousands of accounts to which Twitter had given verification for free.

Twitter will soon add identity-based verification to the Twitter Blue review process, Traughber told employees in the meeting, although he said there was no date yet for when that would be implemented.

In an email to employees early Saturday morning, Musk offered an additional push for Twitter’s creator monetization efforts. Musk told employees they were “most welcome to subscribe to creators that you think produce good content and expense that back to the company.” The New York Times first reported his email.
