Where paid content is concerned, for myself that all comes down to whether or not I have the funds to support other creators I think are worthwhile. Extras and bonus material has never been the dealbreaker for me with that, strictly my own financial situation.
Regarding setting your stories on your email list, I see no reason not to do so. Two emails per week plus whatever one or two scant extras come with the occasional post like this hardly constitutes spam. Considering the potential for added engagement due simply to the reminder that comes from the emails, it'd be worth keeping the Sunday posts on the email list, too. Doubly so if you're not planning to lock them behind a paywall, as that just means an easier way for people to interact fully with what you're writing.
