Business Mailboxes
Mailofly Business Mailboxes gives your organization custom-branded email inboxes (e.g.alex@yourdomain.com, support@yourdomain.com) hosted directly on your verified domains—without the expensive per-seat pricing of legacy office suites.
While transactional APIs send outbound notifications, Business Mailboxes provide actual user inboxes where employees and teams can receive, read, search, organize, and reply to incoming mail.
Why Mailofly Mailboxes?
Traditional email workspace providers (such as Google Workspace and Microsoft 365) charge 18+ per user per month. For growing startups, development agencies, and fast-scaling teams with 10–50+ mailboxes, this creates an unnecessary recurring cost. Mailofly changes this model:Technical Architecture
Mailofly Mailboxes are engineered for extreme speed, high reliability, and low storage overhead:- Rust-Powered Mail Core: Driven by Stalwart Mail Server, a state-of-the-art mail server written in Rust offering memory safety, sub-millisecond execution, and RFC compliance.
- Dynamic SQL Directory: Authenticates dynamically against Supabase PostgreSQL views (
public.stalwart_accountsandpublic.stalwart_emails). When an admin creates or resets a mailbox in the dashboard, it is instantly live on the mail server with zero background synchronization delay. - Infinite S3 / R2 Blob Storage: Message MIME bodies and attachments are streamed directly into cost-effective object storage (Cloudflare R2 / AWS S3 at ~$0.015/GB/mo), keeping container instances lightweight and durable.
- Embedded RocksDB Indexing: Full-text message indexing and cryptographic TLS session caches are stored locally on persistent NVMe volumes for instantaneous inbox search.
- Modern JMAP Protocol (RFC 8620, RFC 8621): Consumed by our Next.js webmail application for ultra-responsive folder navigation, reduced network bandwidth, and efficient battery usage on mobile devices.
