Built around the moment mail actually arrives

Every part of Swiftbox is tuned for the seconds after someone hits send — not the settings page.

Sub-second delivery

Messages route through regional relays, not a single queue, so delivery stays fast even at peak volume.

Search that keeps up

Full-text index rebuilds live as mail arrives — search five-year-old threads as fast as today's.

Private by default

Mail is encrypted at rest and in transit. No content scanning, no ad targeting, ever.

Custom domains

Bring your own domain and get it verified and routing mail within minutes, not days.

Rules that run instantly

Filters and forwarding apply the moment mail lands — no five-minute processing lag.

Built for teams

Shared aliases, delegated inboxes, and audit trails, without needing an admin console degree.

Security that doesn't slow anything down

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.

  • End-to-end encryption for messages between Swiftbox accounts
  • Hardware-key and passkey sign-in, no SMS fallback required
  • Automatic SPF, DKIM and DMARC on every connected domain
  • Full account activity log, exportable any time

What people switch for

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.

Questions people ask before switching

How long does migrating a domain take? +

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.

Can I keep my existing email address? +

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.

What happens to old mail when I migrate? +

Existing mail is imported in full, including folders and read/unread state, and is searchable immediately — it isn't queued for later indexing.

Do you offer a service-level agreement? +

Team and Enterprise plans include an uptime SLA. Enterprise plans can add a dedicated delivery pool for guaranteed throughput during peak sending periods.
