Two mailboxes to start, not one for everything

You'll know how many mailboxes your business needs, what each one is called, and which one you should never mix with bulk sends.

You've reserved the domain and you're about to sign up for email. Before you hit "create account," there's a decision that seems small but isn't: how many addresses you're going to open with that name.

If you open just one, everything gets jumbled together: a customer's booking, the invoice from your internet provider, and an email from a newsletter you signed up for by accident. If you open ten, half of them go unread by next month.

The deciding factor isn't how many people work with you. It's how many different tasks your email needs to handle, and which of those tasks deserve their own door.

Also, a lot of email providers charge per mailbox. If yours does, every address you open and don't use is a monthly cost that gives you nothing back.

One task, one door

Think of your email like the front counter of your business. If everyone comes through the same door, the customer who wants to book, the vendor sending the monthly invoice, and the curious visitor just asking about prices, you end up serving all three badly.

Splitting by task means each address has an owner and a clear reason to exist. Don't create one "just in case": create it because you already know what email is going to land there every week.

One inbox for everything, or one per task

A single inbox

Easy to keep an eye on: you only check one place
Everything mixed together: tomorrow's booking gets lost among vendor spam
If you ever use it to send mass emails, it drags everything else down if it ends up flagged as spam

One inbox per task

You know what to expect in each inbox: bookings in one, invoices in another
You can give access to just that inbox to whoever handles it, without showing them the rest
It means checking more than one place, so it's only worth it if each inbox actually gets real mail

Which one should you pick: Start with two mailboxes if you're working solo: one for customers and one for admin. Add a third with your name on it as soon as you're negotiating in person with vendors or partners; don't create a fourth until one of those inboxes genuinely becomes a mess.

The three that cover almost any business

Almost no business needs more than three to start. The first one faces the public: this is where bookings, price questions, and complaints land. You or whoever handles customers checks it, and it should always get a response in hours, not days.

The second one is for admin: vendor invoices, bank notices, paperwork. It doesn't need a fast reply, but someone should check it once a week so it doesn't get lost among customer messages.

The third one has your name on it. It's the one you use when you personally negotiate with a vendor or partner: it builds more trust than a generic address, and nobody else shares it.

The inbox name is a decision too

"hello@" sounds like you're answering in person; "info@" sounds like a call center. If your business runs on personal connection (a hair salon, a small clinic, a repair shop), use the first one: whoever writes to "hello@" expects a reply in your voice, not a template.

If the volume is high and a team answers, "reservations@" or "orders@" makes it clear what can be requested there, and skips the forced tone of pretending one person is writing when it's really five.

For the admin mailbox, a neutral name works well: "invoices@" or "admin@" doesn't need warmth, it needs the vendor to know where to send the paperwork.

The inboxes of a hair salon with its own domain

hello@yoursalon.com: bookings, customer questions, everything the front desk handles. invoices@yoursalon.com: product suppliers, rent, your accountant. ana@yoursalon.com: the email Ana uses to negotiate directly with her trusted distributor.

When it falls short

It stops working once one of those inboxes starts mixing two different jobs again. If "hello@" gets both bookings and résumés from people who want to work with you, split it into two.

It also falls short when someone other than you needs access to one inbox without seeing the others: that's when the admin inbox truly becomes its own thing, with separate access for whoever handles the books.

And it falls short the other way around too: if you opened three inboxes and haven't checked one in months, merge it. A dead inbox is worse than not having one: people might keep writing to it thinking you're reading it, while you have no idea.

Don't mix your customer inbox with your marketing inbox

The costly mistake is using the same "hello@" for bookings and for mass emails, a promotion, a monthly newsletter. If that mass mailing gets flagged as spam, it drags your real bookings down with it: they start landing in your customers' spam folder without anyone noticing. Keep mass mailings in a separate tool and leave your public-facing mailbox for one-on-one conversations.

What you walk away with

You know how many inboxes you'll create with your domain: probably two if you work solo, three if you personally negotiate with vendors
You're clear on which task belongs to each one: customers, admin, your name
You've chosen each inbox's name based on the tone you want people to use when writing to you
You know the customer-facing inbox never gets shared with mass email sends
Next up is deciding who actually keeps those emails safe
