No minimum number of mailboxes and no setup fee. Ten people on Mail Pro is PLN 1,440 net per year, paid up front — exactly what the table says, with no line items that only appear after signing.

Your mail does not land in spam. Here is exactly why:

Since February 2024 Gmail and Yahoo require sender authentication, and domains without SPF and DKIM get filtered or rejected outright. This is not a premium add-on, it is the price of entry. We configure the full set on the day your mailbox goes live and we read the DMARC reports, so you find out when someone tries to impersonate your domain.

We will not promise you a deliverability percentage, because it also depends on what you send and to whom. We are accountable for our side of it, and that side is checkable: the list below is either done or it is not.

What we set up on day zero

  1. SPF — a DNS record naming the servers allowed to send on your behalf.
  2. DKIM — a 2048-bit key generated for your domain alone, signing every outgoing message.
  3. DMARC — a policy for impersonation attempts, plus the reports we read instead of you.
  4. Reverse DNS and From header — aligned with your domain, no open relay.
  5. Spoofing alert — you get a message when DMARC reports show mail sent from your domain by someone else.

A dedicated sending IP with its own reputation comes with the Enterprise plan.

02 / WHAT YOU GET

Email isn't a text file. We don't treat it that way

Webmail, mobile sync, calendar, contacts — a coherent platform. No buying a client and server separately.

01 / CollaborationEveryday work for the team

Business email is not just a mailbox. It is the calendar you book a meeting in, and the contact that appears on your phone right after a colleague adds it.

Webmail in your language
Responsive, with address book, calendar and task list. Two-factor login and PGP encryption for the messages that need it.
Phone stays in sync Mail Pro+
IMAP IDLE for mail, CalDAV and CardDAV for calendar and contacts. Set it up once, it runs in the native iOS and Android apps.
CalDAV calendar Mail Pro+
Meetings, reminders, iCal invitations, shared team calendars. Works with Apple, Google and Outlook.
CardDAV contacts Mail Pro+
Shared address books and distribution lists, synced to the phone.

02 / DeliverabilityGetting the mail delivered

SPF, DKIM and DMARC included
Configured on day one. We read the DMARC reports and alert you when someone impersonates your domain.
Antispam and anti-phishing
Rspamd and SpamAssassin, greylisting, anti-spoofing rules. You browse the quarantine yourself and release a message in one click.

03 / ComplianceWhen an audit or a dispute arrives

WORM archive with retention Mail Business
Mail backups reaching far back plus full access to logs, so you can reconstruct both the content and who sent it when.
Migration from Gmail and Microsoft 365
IMAP sync with folders, labels, calendar and contacts. We switch MX only after verification, so nothing is lost.

On Gmail, Office 365, Zimbra? — We migrate in 24 h, without losing emails.

Migration from Google Workspace, Microsoft 365 / Exchange Online, Zimbra, your own Postfix/Dovecot. We sync IMAP including folders, labels (Gmail labels), calendar and contacts. The old mailbox stays active until migration is complete, MX switches when new is verified — clients don't lose a single message.

03 / FAQ

Common questions — business email

How does mail work on a phone?
Over IMAP IDLE, which pushes new mail instantly, plus CalDAV and CardDAV for calendar and contacts (Mail Pro plan and above). You configure it once in the native Mail / Calendar / Contacts app on iOS or Android, with no third-party client. Exchange ActiveSync is not supported — if your company runs MDM policies that require EAS, say so upfront, because it changes the recommendation.
Can I use Outlook / Thunderbird / Apple Mail?
Yes. Any email client supporting IMAP/SMTP — Outlook (any version), Thunderbird, Apple Mail, eM Client, Spark, Spike. We send configuration as a .mobileconfig profile (Apple) or auto-discover XML (Outlook).
What about GDPR and data storage?
Mail runs in the Polish data centres of our infrastructure providers, with no data transfer outside the EEA. Data Center IQ holds ISO 27001, ISO 22301 and ISO 9001 certificates and PCI DSS compliance — these belong to the data centre operator, not to FlexNet, and you can verify them there. . We sign a Data Processing Agreement (DPA) as standard. Mail Business plan — 10-year archive compliant with GDPR and criminal code, immutable (WORM). Enterprise plan — encryption at rest (AES-256), DLP, audit log.
What if the mailbox fills up?
You receive an email alert at 80%, 90% and 95% capacity. You can: a) increase capacity (plan upgrade or additional GB), b) delete old emails, c) export an archive (Business+ plan). Emails don't disappear automatically — after 100% new emails bounce, but existing ones stay untouched.
Can I have a mailbox without a website?
Yes — this plan is exactly for that scenario. The domain can be registered anywhere, we only take over MX records. The website can be on a different hosting (or not exist at all) — email works independently. We add a mailbox to an existing domain in 1 hour.
How do we differ from Gmail and Office 365?
Three things. First — price: 5–24 PLN net/mailbox vs 28–88 PLN at Google/Microsoft (and no minimum mailbox count). Second — servers in PL/EU, full GDPR control, no data transfer to the US. Third — support in English and Polish, email goes to an engineer, not a support team overseas.
