How to Set Up Business Email on Your Domain (Step-by-Step)

If your customers still email you at a free @gmail.com or @yahoo.com address, you are leaving trust on the table. A professional address like you@yourcompany.com signals that you run a real business — and it gives your team a clean place to send, receive, and share work mail.

This guide shows you how to set up business email on a domain you own using MailShrine Business Email: add the domain, publish the DNS records we show you, create mailboxes, add aliases like hello@, then open webmail and send a test. You do not need Google Workspace, Microsoft 365, or a full productivity suite just to get professional mail.

Real-life example: Bloom & Bake

Adaobi runs Bloom & Bake, a small bakery in Lagos. She bought the domain bloomandbake.ng for her website, but orders still arrive at bloomandbakeorders@gmail.com. Clients sometimes ask if the shop is legitimate. Her cousin keeps missing inquiries because they share that one Gmail login.

Adaobi’s goal for one Saturday afternoon:

1. Use adaobi@bloomandbake.ng for her own inbox.
2. Use hello@bloomandbake.ng so staff can reply to customer questions without sharing her password.
3. Keep the website on its current host — only email DNS changes.

We will follow Adaobi’s path below. Swap her domain for yours.

What you need before you start

Important: Your website host and your email host can be different. Changing MX / email TXT records does not move your website — as long as you leave A / CNAME records for the site alone.

Step 1: Open MailShrine Business Email

1. Sign in at MailShrine (or create an account).
2. Open Business Email from products / the suite switcher.
3. Land on the dashboard Overview. From here you will use Domains, then Mailboxes.

Pick a plan that matches how many mailboxes you need (Free is fine for one mailbox while you learn; Solo / Team / Business unlock more seats and storage). You can upgrade later without redoing DNS.

Step 2: Add your domain

1. Go to Domains.
2. Enter your domain exactly as customers type it — for Adaobi: bloomandbake.ng (no https://, no trailing slash).
3. Continue. MailShrine creates the domain in your workspace and shows the exact DNS records to publish.

You should see status like Pending until MX / authentication records verify. That is normal.

Step 3: Publish MX, SPF, DKIM, and DMARC

MailShrine shows you the records for your host. Copy them into your DNS panel. Here is what each one does in plain language:

MX — “Where should inbound mail go?”

MX records tell the internet which mail server receives email for @yourdomain. Without correct MX, people cannot deliver mail to your new addresses.

Typical pattern (values are examples — always paste what MailShrine displays):

SPF — “Who is allowed to send as us?”

SPF is a TXT record that lists authorized sending systems. It reduces spoofing and helps inbox providers trust your outbound mail.

Example shape:

• Host: @
• Value: v=spf1 include:… ~all

Critical: Publish only one SPF TXT record per domain. If you already have an SPF from your website host or an old email provider, merge includes into a single v=spf1 … line instead of adding a second record.

DKIM — “Was this message really from us and unaltered?”

DKIM publishes a public key so receivers can verify signatures on outbound mail. MailShrine shows you the hostname (often a selector like mail._domainkey) and the value to paste.

DMARC — “What should receivers do if checks fail?”

DMARC sits at _dmarc and starts safely in monitoring mode:

• Host: _dmarc
• Example value: v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com

Start with p=none for at least a week or two while you confirm real mail is passing. Tighten to quarantine or reject later.

Registrar tips

After saving, return to MailShrine and start verification. You can leave the page; verification keeps checking as DNS propagates.

Step 4: Wait for verification (and fix common blockers)

DNS is not always instant.

When the domain shows Verified (and mail-server setup is complete if shown), you are ready for mailboxes.

Step 5: Create your first mailbox

1. Open Mailboxes.
2. Choose the verified domain.
3. Pick a local part: Adaobi chooses adaobi → adaobi@bloomandbake.ng.
4. Set a strong password (or finish setup if the dashboard asks you to complete provisioning).
5. Save.

You now have a real mailbox with the storage included on your plan (for example Free includes 1GB; higher plans include more per mailbox).

Step 6: Add role addresses with aliases

Adaobi does not need a second paid seat just so customers can write to hello@.

1. Open the mailbox settings for adaobi@bloomandbake.ng.
2. Add an alias: hello on bloomandbake.ng.
3. Mail to hello@bloomandbake.ng lands in Adaobi’s mailbox (or a shared mailbox if you invite team access later).

Free plans include a small alias allowance; Solo and above unlock unlimited aliases — check Billing / Overview meters for your workspace.

Step 7: Open webmail and send a test

1. Open MailShrine webmail for the new address.
2. Send a test message to your personal Gmail/Outlook.
3. Reply from Gmail back to adaobi@bloomandbake.ng and confirm it arrives.
4. Optional: send from hello@… (or reply-as alias if enabled) so the public address looks right.

If outbound goes to spam on first send, wait for SPF/DKIM/DMARC to fully propagate and avoid marketing language in the first test (“BUY NOW!!!”). A plain “Testing my new business email” is enough.

Step 8: Connect phones and Outlook (optional)

Most founders live in webmail for week one. When you are ready:

• IMAP (incoming) and SMTP (outgoing) settings appear in mailbox / client help inside the product.
• Typical ports: IMAP 993 (SSL), SMTP 587 (STARTTLS) — confirm against the exact hosts MailShrine shows.
• On iPhone: Settings → Mail → Accounts → Add Account → Other → add IMAP.
• On Outlook: add the account with the same IMAP/SMTP values (or the guided client setup when available).

We cover deeper client walkthroughs in the Clients & Devices guide category.

Adaobi’s finished setup (checklist)

By the end of the afternoon Adaobi has:

• Domain bloomandbake.ng verified in MailShrineCompleted
• MX + SPF + DKIM + DMARC published at her registrarCompleted
• Mailbox adaobi@bloomandbake.ngCompleted
• Alias hello@bloomandbake.ngCompleted
• Successful send + receive test via webmailCompleted
• Outlook on the bakery iPad (scheduled for Monday)Not completed

Her website is unchanged. Only email routing moved.

Common mistakes to avoid

1. Changing A records “just in case” — can take your website offline. Touch only the mail records MailShrine lists.
2. Leaving old MX records — inbound mail may bounce between hosts.
3. Two SPF records — creates SPF permerror; merge includes.
4. Proxying MX on Cloudflare — use DNS-only.
5. Creating mailboxes before the domain verifies — finish DNS first so provisioning and delivery are clean.
6. Sharing one mailbox password with the whole team — use aliases + team access invites instead of password sharing.

How this differs from Google Workspace “email setup”

Google Workspace and Microsoft 365 are full suites (Docs, Drive, Meet / Office, Teams). They are excellent when you need that whole stack.

If you mainly need professional mailboxes on your domain, a focused host like MailShrine Business Email is usually faster and cheaper: connect the domain, publish the records we generate, create mailboxes and aliases, and open webmail.

For deliverability beyond mailbox mail — for example bulk marketing campaigns — use MailShrine Email Marketing with proper authentication on the sending side. That is a different job from day-to-day business inboxes.

Check your work

1. Domain status Verified in MailShrine Domains.
2. Mailbox listed as active / provisioned.
3. External round-trip: send to Gmail and reply back.
4. Optional: look up your domain with an MX / SPF / DMARC checker (we are shipping free checkers under Business Email Tools).
