Business Email Hosting.Free to Start.

There's no catch. The Free plan is free forever: 7 GB of shared storage, 1 domain, webmail, the Mailbux apps and SMTP sending, and outgoing mail carries a small "Sent via Mailbux" footer. Paid plans from $4.95/mo add unlimited business mailboxes and domains, IMAP/POP3 and API access.

Absolutely. We take security and privacy very seriously. All communications are protected with industry-standard encryption. We will never sell your data or display ads in your inbox. Your business is your business.

Yes! We support standard email protocols like IMAP (on paid plans), which allows you to easily migrate your existing emails from other providers using a desktop email client like Outlook or Thunderbird.

On paid plans, yes — unlimited business mailboxes with no per-user fees. The Free plan includes up to 7 business mailboxes. This is perfect for giving every employee an account or creating aliases for different departments like `sales@`, `support@`, or `info@`.

Our free accounts are provided with a generous storage limit suitable for typical business communication. We focus on delivering a high-quality experience for all our users.

Storage scales with your plan — Starter, Professional, and Business each start with their own pool, and Business scales up to 20 TB. Need more than that? Contact sales and we'll size a plan for you.

Yes! JMAP and SMTP work on every plan, including Free, for our webmail and apps; standard IMAP and POP3 access for clients like Outlook or Apple Mail is available on paid plans.

Yes! Mailbux provides a full REST API that lets you programmatically manage email accounts, domains, and more. You can also send and receive emails via the API. Access your API keys from the API section in your dashboard. API access is available on paid plans.

We use high-reputation IP addresses and employ modern authentication standards like SPF, DKIM, and DMARC. Our infrastructure is optimized to ensure your emails land in the inbox, not the spam folder.

Free includes 1 domain. Paid plans add unlimited domains, so you can manage email for multiple projects or businesses from a single dashboard.

Yes! You can enable two-factor authentication (2FA) on any email account for an extra layer of security. Once enabled, signing in requires both your password and a time-based code from an authenticator app. You can set this up from your account security settings.

All Mailbux servers are located in the EU — Finland (Helsinki) and Germany (Nuremberg/Falkenstein). Your data is stored and processed entirely within the EU under European data protection laws. Our EU-based infrastructure supports key GDPR principles: EU data residency, encrypted connections (TLS 1.2/1.3), account deletion on request, and data export (via IMAP on paid plans). Your data is subject to EU law, not the US CLOUD Act. Learn more.

Yes, to maintain high deliverability and prevent abuse, each mailbox can send up to 300 messages per hour. This limit applies per individual mailbox, not per domain or tenant. This is more than enough for normal business use, and transactional emails are allowed on all plans.
