You just registered your domain, and the setup screen asks a question. How many email accounts does a small business actually need? 

Guess too high, and you overpay for empty inboxes. Guess too low, and you scramble to fix it later.

The honest answer is smaller than most people expect. You need a paid mailbox for each person who writes emails. 

Everything else can usually run on free aliases instead.

This guide gives you a simple formula and a size-by-size table. Let’s start with the two words that are confusing.

The short version

• Count one paid mailbox for each person who sends an email in their own name.

• Add a mailbox for a shared address only if the team works it.

• Use free aliases for info@, sales@, hello@, and similar contact addresses.

• A team of five usually needs five or six mailboxes, not fifteen.

Accounts, Mailboxes, and Aliases: What Is the Difference?

People say email accounts, but they mean two different things. Some mean the paid inboxes they log into. Others mean the addresses customers can write to.

A mailbox has its own login, storage, and password. Providers usually charge you for each mailbox you create. An alias is an extra address that delivers to an existing mailbox.

So you can show clients many addresses while paying for a few mailboxes. That gap is exactly where small businesses save money.

The Simple Formula for Counting Your Email Accounts

Use this simple three-part count to get your number. Add mailboxes for people, mailboxes for shared teams, and a small growth buffer. 

Skip the aliases, because your plan already includes them.

Part 1: One mailbox for each person who writes emails

Count every person who sends an email as themselves. That includes you, your staff, and long-term contractors who talk to clients. Give each person a separate login so accountability stays clear.

Never let two people share one personal mailbox login. Shared passwords make it hard to track mistakes. They also make offboarding messy when someone leaves.

Part 2: A mailbox for each shared inbox where a team works together

Ask one simple question about every shared address. Does a team need to read and reply to it together? If yes, give that address its own mailbox. If not, an alias will do the job.

A support@ address used by three people needs a mailbox. A sales@ address that only reaches you does not. The first needs shared history, and the second needs only delivery.

Part 3: A small growth buffer

Add one spare mailbox, or about 10 percent, for your next hire. This avoids a rushed upgrade when a new person starts. Do not overbuy, though, because empty inboxes still cost money.

How Many Email Accounts Do You Need for Your Size?

Now apply the formula to your own situation. The table below shows typical counts and the matching Truehost plan.

Business size	Mailboxes	Useful aliases	Matching plan
Solo owner	1	hello@, billing@, admin@	Workplace Starter, $0.40/mo*
2 to 3 people	2 to 3	info@, sales@, billing@	Workplace Pro, $1.05/mo*
4 to 5 people	4 to 5	info@, support@, billing@	Workplace Business, $1.85/mo*
6 to 10 people	6 to 10	sales@, support@, hr@, billing@	Workplace Premium, $3.67/mo*
11 to 20 people	11 to 20	One per department	Workplace Enterprise, $7.33/mo*

Truehost prices apply when you pay every three years, in USD. Mailbox counts include shared inboxes. Plans include 10 to 200 aliases, depending on the tier.

Notice that each plan bundles mailboxes and aliases together. You buy one tier instead of tracking individual seats. 

Per-user pricing works differently because every new person raises your monthly bill.

Also, check the storage that each mailbox receives. Starter gives 3GB, Pro gives 5GB each, and business gives 10GB each. Teams that send heavy attachments should size up early.

Take a five-person studio that also wants a shared support inbox. That adds up to six mailboxes, which outgrows the five in business. 

The studio can move up to Premium, or make support@ an alias instead. The right choice depends on whether the team works in that inbox together.

An Example of Twelve People, Four Shared Addresses

Let’s test the formula on a realistic team. Picture a twelve-person delivery company where three people answer customers.

Start with twelve mailboxes, one for each person. The support team works support@ together, so it becomes mailbox number thirteen. 

Meanwhile, info@, billing@, and admin@ each reach one person, so they stay aliases.

Add one spare mailbox for the next hire, and the total reaches fourteen. 

Premium’s ten mailboxes would fall short of that total. That fits comfortably inside the twenty mailboxes of Workplace Enterprise. 

Counting every address as a mailbox would have given seventeen instead.

Which Addresses Should You Create?

Five address types cover almost every small business. You rarely need all five on day one.

• [email protected] for direct conversations with clients, partners, and vendors.

• hello@ or [email protected] for your website, business cards, and social profiles.

• [email protected] for invoices, receipts, and payment reminders from clients.

• [email protected] for customer questions, ideally as a shared mailbox for your team.

• [email protected] for banking, domain, and hosting logins, and never publish it.

For the best security, give admin@ a private mailbox. On a tight budget, an alias still keeps the address private. Just remember that it lands in your main inbox.

Notice the difference between personal and role-based addresses. Role addresses like billing@ survive staff changes, because you hand them over. 

Personal addresses build direct relationships, so use them for client conversations.

What You Should Not Count

Most overcounting comes from three common habits worth fixing. Let’s clear them up one at a time.

Automated senders

Addresses like no-reply@ and orders@ are usually sent from your online store or app. They do not send from your email host. They need correct SPF and DKIM records, not a paid mailbox.

Your personal inbox

Your personal Gmail address sits completely outside this count. Keep it for friends, family, and anything unrelated to the business. Mixing the two makes scam emails harder to spot.

Catch-all addresses

A catch-all receives mail sent to any address on your domain. It catches typos, but it also attracts heavy spam. Create real addresses for anything customers will use.

What Does the Right Number Cost?

Per-user plans often charge $3 to $15 per person each month. A ten-person team could pay $360 to $1,800 a year on those rates. 

That is why the mailbox count matters so much.

Our Workplace Premium covers ten mailboxes for $3.67 a month, on three-year billing, which comes to about $132 upfront. Big suites include more apps, so compare the features you actually use.

Where Truehost Workplace Stands Out

Every Workplace plan includes two-factor authentication, antivirus checks, and anti-spam filtering. You also get Drive storage plus Docs, Sheets, and Presentations. Aliases and forwarding rules come built into each plan.

Are you moving from another provider right now? 

Truehost migrates your emails for free, with no downtime. Support answers by chat, phone, or email around the clock. You can pay by card or use M-Pesa if you work in Kenya.

Some competitors charge strictly per person for each mailbox. Cyber Grapes, for example, starts at $1.99 per user each month. NevTan Mail offers ten free mailboxes at 5GB each.

Free tiers work well until you hit the cap. Check support hours and renewal terms before you commit.

Set Up Your Addresses in Four Steps

You can finish this in about an hour. Follow the four steps below in the order shown.

Step 1: Register your domain and pick a naming pattern

Pick one naming pattern before you create any mailbox. Firstname@ and first.last@ both work well for small teams. Changing the pattern later means updating every signature and invoice.

Step 2: Choose the plan that fits your count

Match your mailbox total from the table to a plan. Leave room for one spare mailbox if a hire is coming. You can upgrade later as your team grows.

Step 3: Create mailboxes, then add aliases

Create one mailbox for each person on your team first. Then add aliases like hello@ and billing@ for the right owner. Send a test message to every address before you announce it.

Step 4: Secure everything

Publish the SPF, DKIM, and DMARC records your host provides. Switch on two-factor authentication for every single mailbox. Both steps take minutes and protect your sender’s reputation.

Keep the Count Honest With a Quarterly Check

Review your mailboxes and aliases every three months. Deactivate accounts for people who left the business. Unused inboxes cost money and quietly create security gaps.

When someone leaves, do not delete their mailbox right away. Forward it to their manager for a short period, then remove it. A deleted mailbox takes all of its history with it.

The Bottom Line

So how many email accounts does your business actually need? Count one mailbox for each person who writes emails.

Add mailboxes only for shared inboxes that the team works on together. Use aliases for every other address you want clients to see.

That approach keeps your costs low and your structure clear. Now the setup screen stops feeling like a trick question.
