Launching on Apple Podcasts & Spotify

I'm launching Leonardo English (currently just hosted on leonardoenglish.com) on Apple Podcasts / Spotify / etc (via Transistor) by the end of the month.

At the moment the content is only hosted on the website, and I have been building up a small audience and testing out different types of content.

Does anyone have experience or tips on the actual 'launch' of a podcast, starting from the point of view not having any real kind of pre-existing list / audience?

@mijustin suggested back in this post (https://www.indiehackers.com/post/when-to-launch-a-podcast-aad9d7bdcd) that the number of early listens / downloads is an important factor, but I'd be curious to hear from any other indiehackers who have been in the same situation...
