How to Create Your First Business Email Account
Why Your Business Needs a Professional Email Address
Using a generic Gmail or Yahoo address for business communication undermines your credibility before you even say hello. A professional email like [email protected] signals that you are serious, trustworthy, and established.
In this guide, you will set up a complete business email from scratch on Mailbux: add your domain, configure DNS records, create your first email account, and start sending professional emails in minutes.

Step 1 — Add Your Domain
The first step is to connect your business domain to Mailbux. If you do not have a domain yet, register one through a registrar like GoDaddy, Namecheap, or Cloudflare before proceeding.
- Sign in at dash.mailbux.com (new accounts start in the onboarding wizard), then open Services → your plan → Manage → Domains.
- Choose Add domain.
- Enter your domain name (e.g., yourcompany.com) and click Save.
Mailbux will then show you the DNS records you need to add at your domain registrar.
Step 2 — Configure DNS Records
DNS records tell the internet how to route email for your domain. You need to add two records at your domain registrar or DNS provider: an MX record (to receive email) and a TXT record (for SPF, which helps prevent spam).
Add the following records in your DNS management panel:
| Record | Type | Host | Value | Priority |
|---|---|---|---|---|
| MX | MX | @ | my.mailbux.com | 10 |
| SPF | TXT | @ | v=spf1 include:msg25.com ~all | — |
Where to add DNS records at your provider
If you are not sure where to find your DNS management panel, use one of these guides from your provider:
- GoDaddy — Manage DNS Records
- Namecheap — Change DNS for a Domain
- Cloudflare — Create DNS Records
- Google Domains — Manage DNS
- AWS Route 53 — Create Record Sets
- Hostinger — Add DNS Records
Note: DNS changes can take up to 48 hours to propagate, but typically complete within 1–2 hours.
Step 3 — Verify Your DNS Records
Once you have added the records, verify that they are live and correct.
Using the Mailbux DNS checker
Open Manage → DNS. Every record (MX, SPF, DKIM, DMARC) is listed with a copy button; checks run automatically, so choose Re-check after editing.
Using msg25.com tools
You can also double-check your records using these free tools:
- MX Lookup — verify your MX records point to my.mailbux.com
- SPF Checker — confirm your SPF record includes msg25.com
- DNS Lookup — check all DNS records for your domain
- Blacklist Check — make sure your domain is not blacklisted

Step 4 — Create Your First Email Account
With your domain verified, you are ready to create email addresses.
- Open Manage → Mailboxes and choose Create mailbox.
- Enter your desired email address (e.g., [email protected]).
- Fill in the display name, a strong password and the storage (at least 1 GB per mailbox).
- Click Save — your email account is live and ready to use.
The Free plan includes up to 7 business mailboxes, and paid plans add unlimited business mailboxes: info@, support@, hello@, or personal addresses for each team member. Mailbux does not charge per user.
Step 5 — Start Using Your Email
Webmail
The quickest way to get started is through the Mailbux webmail. Open https://exp.mail.mailbux.com (or Manage → Connect → Open Webmail) and sign in with your full email address and password. No setup required — it works instantly in your browser.
Desktop and Mobile Apps
To use your email with Outlook, Apple Mail, Thunderbird, or any other IMAP/SMTP client, open Manage → Connect. It shows the exact server, port and security values for each mailbox, plus step-by-step guides for Apple Mail, Outlook, Thunderbird and Android:
- Incoming mail (IMAP): my.mailbux.com, port 993 (SSL/TLS)
- Outgoing mail (SMTP): my.mailbux.com, port 587 (STARTTLS)
- Username: your full email address (e.g., [email protected])
Note: IMAP/POP3 sign-in needs a paid plan; Free uses webmail, the Mailbux apps (JMAP) and SMTP.
On your phone, install the Mailbux app (iOS / Android). It works on every plan, Free included.
API Access
On paid plans, developers can integrate Mailbux into their applications. Open Manage → API access for API keys and JMAP access.
