How do you use Zapier for growth?

Ok, so I only use Zapier for two things at this point. I sell a product on Gumroad, and I use Zapier to automatically add customers to my email list. I also have contact and affiliate submission forms on my site. I use Zapier to add the Typeform responses to my AirTable tables so that I can sort user questions or keep track of affiliate sales and so on.
