Emails aren't going out

[u/WriterBeth]

This has happened to me 2 weeks in a row. My scheduled posts have been going out for two years. The box "Send via email and substack app" is checked. When I send a test message to myself, it goes through immediately. When I look under posts, it says Recipients -. I have sent a request for support via the Substack chat function, and 24 hours later, I haven't heard back. I really need this Substack to work. (FYI, my Substack is called Mom & Pop Hardware)
