Email on your own domain, kept in your own house.
Professional mailboxes for you and your team. Read them in the browser beside your files and calendar, or in the mail app you already use on your phone and laptop.
What you can do with Mail
Addresses on your domain
Every person, role and shared inbox gets an address at your business’s own domain.
Your inbox in the browser
Open mail.growthstar.app and your inbox is there, inside the same account as your files, documents and calendar.
- Works with the apps you have
- Connect Apple Mail, Outlook, Thunderbird or the mail app on your phone with standard settings.
- Shared addresses
- Route info@ or bookings@ to the right people, so a message to the business reaches whoever handles it.
- Spam filtering built in
- Incoming mail is checked and sorted on arrival, so junk stays out of the way of the messages that matter.
