Use cases
SuperMailOS is managed business email for people who run more than one domain — or one company that deserves better than per-alias pricing. These are the situations it was built for.
Every client's mail in one place, role aliases that outlive staff turnover, and deliverability handled for domains you don't control the DNS habits of.
/use-cases/agencies
Teams & companies→hello@, support@, billing@ for each product — real inboxes, one team view, authentication records that keep transactional and human mail clean.
/use-cases/saas
Teams & companies→orders@ and support@ aliases that cost nothing, on a domain where receipts and customer answers both land in the inbox.
/use-cases/ecommerce
Teams & companies→Per-person pricing that fits a donation budget, role aliases (info@, donations@) that persist across volunteer changes.
/use-cases/nonprofits
Individuals & portfolios→The portfolio story: every product's email, one inbox, one bill. Ship a new product, add its domain, get hello@ in minutes.
/use-cases/startup-founders
Individuals & portfolios→you@yourdomain.com credibility without per-alias fees — one cheap mailbox, unlimited aliases as your services grow.
/use-cases/freelancers
Individuals & portfolios→A from@ address on your own domain with authentication set up right, because list mail dies in spam without it.
/use-cases/creators
Individuals & portfolios→Listing-heavy communication that must not land in spam, shared role addresses for a team of agents.
/use-cases/real-estate
