I already do that too. Post on Patreon, voting, links to YouTube, everything. Of course, I do that “announcement” post before the broadcast actually airs, several days in fact so people can block it in their calendar if they want. So if they get notified about that post, they also have a lot of time to forget the date and time again when the broadcast actually DOES start
A lot of my Patrons have also complained that they do not receive notifications from Patreon at all (I’ve already told them to check their notification settings and their spam folder), so I’ve also taken to using a dedicated twitter account now where I post links to all posts in the activity feed with pledge level indicator (manually, because apparently there’s no way to automate that yet?), plus the occasional “broadcast starts soon”, and also a calendar feed provided by eventtolist that they can subscribe to to get actual calendar entries for upcoming broadcasts.
The latter is something I’d love to see on Patreon natively however, combined with a new “event” kind of post (including timezone information!).
You already - as far as I understand - have something similar going on for custom RSS feeds for podcasts with restricted episodes, so allowing personalized calendar feeds with events might even be within reach already (I’m a software developer, I know that engineers hate it when outsiders who don’t know the codebase say something like that, so take it with a grain of salt, don’t want to step on any toes :)) Just like with RSS there do exist established standards for something like that that work with people’s calendars (ICAL). Combine that even with an additional notification via email + app 5min or something before an event starts and chances are way higher that people won’t miss it.
