For many types of software—file sharing, projects, and content management or eCommerce especially—it often makes sense to self-host apps, customize them for your needs, and run them from your own server once your company's large enough. Not email. Sending emails from your own server simply is too much trouble for all but the largest companies. You'll likely see your emails blocked by spam filters, or your servers swamped when you send messages to a large list.

SendX prides themselves on being a simple email marketing solution aimed at non-marketers. One of their most unique features is “Opti-Send technology” which automatically resends campaigns to contacts who didn’t open the first email, boosting open rates. This has been considered a best practice in the email marketing space for many years, yet is surprisingly manual to set up in most email marketing tools.
Maybe the most interesting result is that Annihilation (16) and Hereditary (15) do much worse under IRV. While they are included on enough ballots to do well under this page's system, they don't have the kind of broad critical consensus needed to win an instant runoff vote. Perhaps this reflects the critical bias against sci-fi and horror? You decide.
