№ 003 — Questions, answered
On EU infrastructure — currently Germany (Contabo, Nürnberg) — under GDPR, NIS2, and the EU Charter of Fundamental Rights. The contract is governed by Luxembourg law, with the CNPD as supervisory authority; the DPA reflects that without a schedule-II 'international transfer' annex. The software stack is open source, auditable end-to-end. If foreign-jurisdiction extra-territoriality (US CLOUD Act, FISA 702, equivalents elsewhere) matters to your threat model, ask — we'll walk through it.
Yes. At any time, including after a 30-day free trial of Mesh or Fleet, you get a full export of every mailbox (EML + maildir), every file (in original formats), every calendar (iCal), every contact (vCard) and every database row that's yours. Format is standard — you can re-import into Google Workspace, Microsoft 365, Mailbox.org, anywhere. No proprietary lock-in by design.
Because Core at €7 includes a managed password manager, encrypted off-site backup, enforced MFA, GDPR-compliant DPA, EU-only data residency and ticket support — none of which come bundled at €6.50 with Microsoft. Side-by-side feature parity is closer to Microsoft 365 Business Standard at €13. Core at €7 is ~46% cheaper for the same outcomes.
Yes — when you commit to twelve months. We absorb the onboarding cost (typically 6–15 hours of our time, including mailbox migration up to 25 mailboxes for Mesh, or 5 device enrollments for Fleet). If you want month-to-month flexibility, we charge €490 (Mesh) or €1,490 (Fleet) up front, because we still spend the time. The first five customers get the founding deal: three months free, no commitment, no card on file, no installation fee.
We publish response times, not resolution times — because anyone promising a hard resolution SLA on a deeply integrated software stack is overpromising. Core: 1 business day response. Mesh: 4 business hours. Fleet: 1 business hour, best-effort outside business hours. Status page at status.kiwistack.io. You'll never have to email three times to get a response.
Yes. We publish SPF, DKIM, DMARC and MTA-STS records; we keep the sending IP reputation warm; and for high-volume customers we route outbound through a reputable EU SMTP relay. We test deliverability into Gmail, Outlook, Yahoo, ProtonMail, Mailbox.org and Infomaniak before declaring a tenant production-ready.
Yes. We migrate your domain over (or just the MX records, if you want to keep DNS at your current registrar). Your team's email addresses stay identical: anne@yourcompany.be remains anne@yourcompany.be. They simply log in at a new portal.
Fleet scales above 50 — we just stop publishing prices and have a real conversation. Above 100 users we typically split workloads across two dedicated servers and add a second region for hot standby. Volume discount kicks in automatically: −5% from 25 users, −10% from 50.
