Unlimited Business Email Hosting.100% Free.

There's no catch. Mailbux is a passion project supported by its founders. Our mission is to provide essential business email hosting to startups and small businesses without the financial burden. We may introduce optional, premium features in the future, but the core email hosting platform will always remain free.

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, which allows you to easily migrate your existing emails from other providers using a desktop email client like Outlook or Thunderbird.

Yes, you can create as many email addresses at your domain as you need. 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.

You can upgrade your storage capacity at any time. We offer flexible options that allow you to scale your mailbox storage to whatever you need—even 20 TB, 200 TB, or more. We ensure you have all the space you need as your business grows.

Yes, absolutely! Mailbux supports standard IMAP, POP3, and SMTP protocols, so you can access your business email from virtually any desktop or mobile email client you prefer.

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.

We use dedicated, 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.

No, you can add and manage an unlimited number of your own domains to your Mailbux account. This allows you to manage email for multiple projects or businesses from a single dashboard, all for free.

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. Your data is subject to EU law, not the US CLOUD Act. Learn more.

Yes, to maintain high deliverability and prevent abuse, each email account has the following sending limits: 300 emails per hour and 7,200 emails per day maximum. These limits apply per individual email account, not per domain or tenant. This is more than enough for normal business use, and transactional emails are allowed on all plans.
