What is SuperMailOS?

SuperMailOS offers tailored business email solutions on your own domain, specifically aimed at small teams. By simply providing your domain, you let SuperMailOS manage the mail server, ensuring excellent deliverability with features like SPF, DKIM, DMARC, IP reputation management, and warmup, which help guarantee that your messages land in the inbox rather than being filtered as spam.

The setup is efficient and user-friendly, allowing you to verify your domain in mere seconds using one-click DNS options with platforms like Cloudflare and DigitalOcean, or by following straightforward copy-paste instructions with any domain registrar. Once verified, you can invite team members and start sending emails right away. Each user is provided with a genuine mailbox and enjoys the advantage of unlimited free aliases, such as hello@ and support@, enhancing communication flexibility.

The webmail interface mimics the user-friendliness of Gmail, incorporating features like threaded conversations, instant search functionality, keyboard shortcuts, labels, and dark mode, while also supporting IMAP and SMTP for seamless integration with various email applications. Moreover, SuperMailOS includes a real-time deliverability dashboard that enables users to track where their emails are delivered, providing valuable insights into communication effectiveness.

Pricing is transparent, featuring a flat rate per mailbox: the Pro plan is available for $3 per month when billed annually, which includes 10 GB of storage and support for three domains, while the Business plan, priced at $5 per month, offers 30 GB of storage and unlimited domains, with customizable options available for larger teams of 50 or more members. Additionally, a 14-day free trial is offered without the need for a credit card, allowing prospective users to explore the service risk-free and determine if it meets their business needs. This risk-free trial underscores SuperMailOS's commitment to customer satisfaction and confidence in its service quality.
