Hi @Vensy,

Thanks for sharing this question with our community.

We do not have any current plans to build a Newsletter sign-up specifically for Twitter. With that said, you do have the ability to embed a Klaviyo subscribe page (which could feed into your Newsletter list). You can find the URL for your page in a box above the page itself, with a button that says, "Copy URL".  Since this is a public-facing link, users have used this link to display their subscribe pages in a variety of places. For more information on customizing this page, I recommend checking out Understanding Opt-In Related Pages for a List.

You can also embed a Klaviyo sign-up form anywhere on your site.

I hope that’s helpful.
