Isn't your pricing a little of? The free offer seems really good, but the $29 to "just" remove branding feels really high, if you don't need to other stuff in that bundle, especially compared to the $12 as montaigne.io.
Honestly... I'd consider it, but realistically I'd never get around to it, and maybe be slightly afraid that now my blog is trapped in Apple Notes and getting it would be horrible to migrate if your site was to shut down.
If you just want to remove the branding, I view it a $19/$29 subscription for something that's worth maybe $1 - $2.
Maybe also add an explanation as to what a site is, because I can't tell what the difference between a site and a domain is.
