Why Many SMEs Are Acting Now

Dependence on US BigTech for key IT components has become a strategic risk in recent years: political uncertainties, jurisdictional issues, compliance costs, vendor lock-in and increasing complexity.

For medium-sized companies with 50+ employees, email is not a tool - it is a critical part of value creation. We therefore treat the migration like an infrastructure project: with a plan, tests, security standards and a clean handover.

Why mailbox.org (Berlin)

Resilience & Data Protection That Suit SMEs

mailbox.org is a German provider with a clear focus on data protection and security. For many organizations, this is a pragmatic way to set up e-mail and groupware in Europe - without having to forego professional functions.

Typical reasons why customers choose it:

  • German provider / European legal area
  • Standards instead of lock-in (e.g. IMAP/SMTP, CalDAV/CardDAV)
  • Security functions such as 2FA and established encryption options
  • Reliable, traceable operation instead of a "black box"

What makes Blackbit different:

Migration = Operation, Not a Tinkering Project

Many email moves fail not because of "copying emails", but because of:

  • DNS & deliverability (SPF/DKIM/DMARC)
  • Outlook/clients, mobile devices, rights/delegations
  • Shared mailboxes, distribution lists, special cases
  • Missing cutover plan, missing documentation

Our Migration Process

(proven, plannable, documented)

1
Migration check (free of charge)
Inventory: source system, domains, number of mailboxes, data volume, clients, special cases.
2
Target system & security baseline
Users, groups, shared mailboxes, access policies, 2FA policy.
3
Pre-sync in the background
Historical data is transferred while everyday life continues.
4
Cutover window

MX conversion + final delta sync + function/delivery tests.
5
Stabilization & handover
Client conversion, deliverability monitoring, runbook & admin documentation.
The real added value:

Email as a Gateway to a Resilient It and Commerce Infrastructure

Many companies use email migration as a starting point to take a holistic view of the topic of "EU-sovereign operations":

  • Security & compliance (policies, MFA, DMARC reporting, auditability)
  • Operational stability (SLOs, monitoring, incident processes)
  • Cost & efficiency levers (standardization, lifecycle, IT relief)
  • Digital platforms: Store, PIM, CMS, data flows - securely operated and continuously improved

Are you already familiar with our services for operating commerce platforms? If you are interested in reducing complexity and making systems measurably more stable - not just "converting" e-mail - then you should find out more here.

FAQ

The Most Important Answers on E-Mail Migration.

How long does it take? Depending on the number of mailboxes and data volume. We usually synchronize historical data in the background, the cutover takes place in the planned time window.
Is there downtime? Generally very low - the critical point is MX conversion + final delta sync. That's exactly what Pilot + Runbook are for.
Outlook is critical for us - will it work? Yes, this is standard in our projects. We schedule client conversion and support in the cutover window (depending on the package).
Yes, in the migration check we clarify which method (IMAP/Export/Hybrid) makes the most sense for your environment. Do you also migrate from Gmail/Google Workspace?
