Newsletter question ...

I was hoping to create an X platform, but saw that Revue has shut down. What does everyone use now for their newsletters, and how do you combine it with the platforms you’ve created on? I’m specifically looking for something free and user-friendly for newsletter production (and not just a trial period), but can’t find one I like the most. I see wix offers a free plan for up to 200 emails per month, but that isn’t much. Does anyone use mailer lite?

Thank you in advance for your input.
