Twitter will let you subscribe to newsletters with just one tweet

Twitter bought Revue, an email newsletter service, earlier this year in the hopes that it would engage journalists and writers who want to share long-form content without feeling limited by Twitter's 280 character limit. Now, the new integrated service is getting an update.

In a tweet, Revue revealed that users can now subscribe to the newsletter by simply clicking on a link in a tweet. And if a user's email address is linked to their Twitter account, they can now subscribe with one click, with no email verification required.

Reviews note that the feature is currently available for review users on desktop and web, and is set to arrive on Android and iOS in the near future. This comes after it tested a newsletter subscribe button on users' profiles in August.

Twitter's acquisition of Revue put it face-to-face with Substack, a paid newsletter service that helps users establish a readership following. As Casey Newton notes in her article on The Platformer, popularity on Substack largely depends on your audience on Twitter.

"The only way to develop an alternative is through tweets," Newton said after using the service for a year. "I wish I had other clear avenues of growth, but to this day, it really looks like it's Twitter or nothing."

With reviews becoming even more involved in Twitter's interface, one can only imagine the impact this could have on Substack users. Because of its convenience and the fact that it seamlessly integrates into their tweets and profiles, creators may feel more inclined to use Revive instead. While you can point readers to your alternative via social media, it may require better promotional options – perhaps something built into the network. Otherwise, reviews may start to outweigh it.
