In plain English

Small-product builders, creators, and software companies can run their email from Lumail, made by Melvyn. It helps manage mail campaigns, sort subscribers into groups, write messages with AI, track how the mail does, and make a simple page where someone can sign up. Customers pay monthly or yearly based on how many subscribers they have, with extra features on the paid levels, because doing all of that by hand takes time they need for the product itself. The AI does most of the writing and the billing, while Melvyn still checks quality, helps customers, shares the site, and handles unusual mail.
