Multi-Genre Author

Hi Everyone, I meant to ask this of @Thomas Umstattd Jr. on the last Patrons Q&A but I had to sign off before he got to my question. So here it is. Would love any thoughts but will also tag @AI Thomas :

I am already a published author of a couple of theology books. In the works are

  • a multi-book Epic Fantasy series (drafts nearly done for all the books)

  • another theology book

  • two children’s books (drafts done)

  • home-schooling literature books

Writing is not my full-time vocation, and is probably unlikely to be, at least any time soon. However, keeping to one genre simply isn’t possible for me, even if I understand that it is, by far, best practice. So… what are the best practices for platform/promotion for a multi-genre author other than segmenting your mailing list?
