  • 7 GB Shared storage pool

    Shared across all email accounts

    This storage is one shared pool for every email account on this plan.
  • Up to 7 business mailboxes A mailbox is one private inbox with its own address, such as you@yourcompany.com, and its own sign-in.
  • Up to 1 domain A domain is a web address you own, such as yourcompany.com. This is how many domains can send and receive mail on this plan.
  • Up to 5 aliases per mailbox An alias is an extra address that delivers into an existing mailbox — sales@ and info@ can both land in the same inbox without a second sign-in.
  • 300 messages/hour per email account The rate shown on this plan applies separately to each authenticated mailbox, not once across the whole plan. Free plans may have additional anti-abuse safeguards.
  • Webmail & apps Read and send mail in your browser or in the Mailbux mobile apps, from any device. Included on every plan.
  • SMTP Send mail from your own address through your mail app, website contact form or app — not only from webmail.
  • JMAP The modern sync protocol the Mailbux apps use — faster and more battery-friendly than IMAP. Works with any JMAP mail client. Included on every plan.
  • Mail forwarders Automatically pass incoming mail on to another address — inside or outside your domain. Included on every plan.
  • Catch-all address Collect mail sent to any address at your domain that does not exist as a mailbox or alias, so a typo never bounces. Included on every plan.
  • DKIM, SPF and DMARC included
  • Spam and virus filtering
  • IMAP & POP3 On paid plans Without IMAP or POP3, mail apps such as Outlook, Apple Mail, and Thunderbird cannot connect on this plan. Use webmail or a JMAP-compatible app instead, or pick a paid plan to unlock them.
  • API access On paid plans
  • Sent by Mailbux footer Included on outgoing mail Sent by Mailbux footer. Included on outgoing mail.

Built for real business email, not spam

Each authenticated mailbox can send up to 300 messages per hour. Free plans can also use separate daily and recipient safeguards; normal deliverability protections always apply.

Allowed

  • Transactional email
  • Genuine business correspondence
  • Newsletters to verified opt-in subscribers you own
  • Legitimate, legal email of any kind

Not allowed

  • Bulk or mass email
  • Cold outreach or unsolicited marketing
  • Purchased or rented lists, spam, phishing
  • Anything that harms deliverability or reputation

FAQ

Frequently asked questions

It is one private inbox with one professional email address, such as you@yourdomain.com. Each plan card shows how many business mailboxes it allows.

The storage amount shown is one total pool shared by every mailbox on the plan. Creating another mailbox does not add storage; mailbox usage draws from the same pool.

No. An alias is another address that delivers to an existing mailbox. It has no separate inbox, sign-in, or storage allocation, and each plan shows its published alias limit per mailbox.

Every plan includes 300 messages/hour per email account. The limit applies separately to each signed-in account, not once across the whole plan. Free plans may also have daily or recipient anti-abuse safeguards.

Mailbox and domain allowances control how many inboxes and domains you can create. Storage is different: every mailbox on the plan draws from one shared storage pool, so adding a mailbox does not add another storage allocation.

Yes, connect a domain you control and use the guided DNS setup. A service subdomain is available only when explicitly enabled for the selected service; it does not replace your plan domain allowance.

When a Free plan is offered, use its card as the source for mailbox, domain, alias, storage, and sending limits. It may also restrict IMAP, POP3, API access, some high-risk domain endings, and add a brand footer to outgoing mail.

Paid plans include IMAP, POP3, SMTP, JMAP, webmail, and supported mail apps. A Free plan can disable IMAP, POP3, and API access; its comparison column shows the protocols included before you choose it.

Yes. Review the change from your account before confirming it: the preview shows any prorated charge or credit and when the new billing takes effect. A downgrade can require mailbox, domain, or storage usage to fit the lower plan first; existing mail is not silently deleted.

Yes. Contact support for a guided migration assessment before moving mail so the source, volume, access method, and timing can be confirmed. Keep the old service active until you have verified the migrated mail and new delivery path.

Existing mail is not deleted just because the pool reaches its quota, but storing or receiving new mail can be restricted. Free space or increase the plan capacity before normal delivery can resume.

Use the service for genuine business correspondence, transactional mail, and messages to recipients who asked to hear from you. Bulk spam, phishing, purchased lists, and unsolicited outreach are not allowed.
