One inbox for every domain you connect and every address on it lands in one place, with threads, instant search, and labels that work across all of them.
Every new domain came with the same tax: another mailbox bill, another DNS afternoon, another place support mail goes to die. SuperMailOS provides one inbox, one login, one bill.

Anonymous Startup
Only app with an approved peptide shop. I first launched it in early June and it has already done $35K in total rev and $10K MRR. My app's shop page is also monetized with an exclusive peptide partnership that pays me a retainer + commission on sales. Download to paid is over 12% and my daily churn on weekly plan is under 3%. The app is super sticky and it is in a rapidly growing niche with 0 competition.
