SuperMailOS Reviews & Product Details

SuperMailOS is a business email platform for founders, agencies, and teams managing multiple domains. It brings mail from different domains into one inbox, with automatic reply-from addresses, unlimited aliases, shared mailboxes, snooze, search, and filtering rules. Users can access their mail through the web app or connect Apple Mail, Outlook, Thunderbird, and other clients using IMAP and SMTP. The platform includes managed SPF, DKIM, and DMARC, deliverability monitoring, a DMARC reporting dashboard, and two-factor authentication. A REST API and webhooks let developers send, receive, and process email from their applications. Built by Adee Labs, SuperMailOS offers per-mailbox pricing and a 14-day free trial. Customers keep their existing domains and can import or export their mail.
