Swiftbox is a professional inbox built for speed — near-instant delivery, a search index that never lags, and an interface with nothing left to trim. Built on swiftmailbox.net infrastructure, run for people on deadlines.
Every part of Swiftbox is tuned for the seconds after someone hits send — not the settings page.
Messages route through regional relays, not a single queue, so delivery stays fast even at peak volume.
Full-text index rebuilds live as mail arrives — search five-year-old threads as fast as today's.
Mail is encrypted at rest and in transit. No content scanning, no ad targeting, ever.
Bring your own domain and get it verified and routing mail within minutes, not days.
Filters and forwarding apply the moment mail lands — no five-minute processing lag.
Shared aliases, delegated inboxes, and audit trails, without needing an admin console degree.
Swiftbox is built on the assumption that protection shouldn't cost you speed. Everything below runs in the background, on every message, with no setup.
A handful of the people who moved their team's mail onto Swiftbox.
We migrated four domains in an afternoon and the mail didn't stop moving once during the switch.
Search is the whole reason we stayed. I can find a client email from three years ago in under a second.
Support actually answers. We had a DNS issue at 11pm and someone was on it in nine minutes.
Every plan includes custom domains, encrypted storage, and full search. Pay for scale, not features.
Most single-domain migrations complete in under 4 minutes once DNS is pointed at Swiftbox. Larger multi-domain accounts typically finish within the hour, with mail flowing the entire time.
Yes. Bring any domain you own, verify it through a short DNS check, and every address on it continues working with no interruption to incoming mail.
Existing mail is imported in full, including folders and read/unread state, and is searchable immediately — it isn't queued for later indexing.
Team and Enterprise plans include an uptime SLA. Enterprise plans can add a dedicated delivery pool for guaranteed throughput during peak sending periods.
Set up your first address in under two minutes — no card, no commitment.
