Description
Mail-in-a-Box allows you to establish your very own mail service provider with just a few straightforward steps, similar to creating a personalized version of Gmail that you have complete control over.
Essentially, it transforms a new cloud computer into a fully functional mail server, and you don’t need to possess advanced technical skills to get it up and running.
Each Mail-in-a-Box setup comes equipped with webmail access and an IMAP/SMTP server, making it compatible with both mobile devices and desktop email applications. Additionally, it offers synchronization for contacts and calendars, ensuring that all your information stays up to date across devices.
Moreover, the system includes essential mail features such as spam protection through filtering and greylisting, customizable mail filter rules, automatic configuration for email clients, and scheduled backups to services like Amazon S3.
Another advantage is its automatic DNS configuration, which simplifies the process when you allow it to function as your nameserver, enabling it to establish crucial DNS records that enhance mail deliverability and security, including SPF, DKIM, DMARC, and MTA-STS.
Furthermore, when DNSSEC is activated along with DANE TLSA, it significantly elevates the level of security for your email communications.
Description
SuperMailOS provides managed business email services on your own domain, specifically designed for small teams. You simply provide your domain while SuperMailOS takes care of the mail server and ensures optimal deliverability through SPF, DKIM, DMARC, IP reputation management, and warmup, guaranteeing that your emails reach the inbox instead of being marked as spam.
The setup process is quick and user-friendly; you can verify your domain in seconds using one-click DNS with platforms like Cloudflare and DigitalOcean, or follow simple copy-paste instructions with any registrar, then invite your team members and begin sending emails immediately. Each user receives a genuine mailbox, with the added benefit of unlimited and free aliases, such as hello@ and support@.
The webmail interface is designed to be as intuitive as Gmail, featuring threaded conversations, instant search capabilities, keyboard shortcuts, labels, and dark mode, alongside support for IMAP and SMTP, enabling compatibility with any email application. Additionally, SuperMailOS provides a real-time deliverability dashboard to monitor where your emails land.
Pricing is straightforward with a flat rate per mailbox: the Pro plan costs $3 per month when billed annually and includes 10 GB of storage and three domains, while the Business plan is priced at $5 per month, offering 30 GB of storage and unlimited domains, along with customizable options for larger teams of 50 or more. A 14-day free trial is available with no credit card required, allowing you to experience the service risk-free.
