Organization with ppv

Hi, I’m a new creator about a month in. I don’t have a huge backlog of content and as of now I’m making it as I go during sessions, and saving it for later. I’m wondering how you guys avoid accidentally sending repeat ppv to subscribers.

For example, I only have about 4 solo videos so far. Of these I sent some out as ppv mass messages, and a couple I made during a sexting session with an individual subscriber. I’m so afraid I’ll loose track of who I sent it to already and resend it to people who have already purchased.

For you well seasoned, well organized, folks.. how do you go about organizing your content to avoid this? Thank you sooo much for all responses!
