The $0 business email address (and exactly where it breaks)

You do not need to pay for a you@yourbusiness.ca email address. Not “there’s a cheap option” — you genuinely do not need to pay anything, and for a lot of one-person businesses the free version is the right answer rather than the desperate one.

This is the guide nobody writes, because everybody who explains business email is selling business email.

First, the only question that matters

Do you need a mailbox, or do you need an address?

• An address is hello@yourbusiness.ca on your invoices, your van, and your Google Business Profile. Mail sent to it reaches you. You can reply as it. You read and write everything in the inbox you already use all day.
• A mailbox is a separate account that lives at your domain — its own login, its own storage, its own apps, reachable by more than one person and portable to a new owner.

Most solo operators need an address. They think they need a mailbox because that’s what’s for sale.

If you need an address, this guide gets you there for $0 and about 20 minutes. If you need a mailbox, skip to the provider comparison — a real inbox starts around a dollar a month and that’s honest money well spent. The setup guide walks you through it.

The free recipe, in two halves

Here’s the part that trips people up, and it’s the reason most “free business email” guides quietly fail you: receiving and sending are two separate problems. The free tools solve receiving beautifully. Sending takes one more step, and guides that skip it leave you with an address that can’t reply.

We’ll do both.

Half one: receiving (about 5 minutes)

If you followed our hosting guide, your domain’s DNS is already at Cloudflare — so this is in a sidebar you’ve already used, and there’s no new company to sign up with.

1. Cloudflare dashboard → your domain → Email → Email Routing → Get started.
2. Create a custom address: hello@yourbusiness.ca.
3. Point it at the inbox you actually check — your Gmail, your Outlook, whatever you use now.
4. Cloudflare emails that destination to confirm it’s really yours. Click the link.
5. Accept the DNS records it offers to add. It writes its own MX records — you don’t hand-edit anything.

That’s it. Mail to hello@yourbusiness.ca now lands in your normal inbox. Set up as many addresses as you like — hello@, invoices@, mike@ — all pointing at the same place, and a catch-all if you want anything@yourbusiness.ca to reach you. Cloudflare allows up to 200 verified destination addresses per account, which is not a limit you will ever meet.

It costs nothing, and Cloudflare pays us nothing for telling you — the same arrangement we have with them for hosting.

Half two: sending (the part that’s usually missing)

Now the honest bit. Cloudflare Email Routing only receives. It forwards mail to you; it will not send mail as you. (Cloudflare does offer a separate outbound service, but it sits on a paid Workers plan — not part of this free path.)

So if you stop here, you have an address that receives beautifully and then replies from yourname@gmail.com, which rather gives the game away on the invoice.

The fix is Gmail’s “Send mail as” feature, and there are two versions of it. The difference is genuinely worth understanding, because this is where free-email guides either mislead you or stop.

Version 1 — the five-minute one. In Gmail: Settings → See all settings → Accounts and Import → Send mail as → Add another email address. Enter hello@yourbusiness.ca, and let Gmail send it through Google’s own servers. Gmail sends you a confirmation code at that address — which now works, because you just set up half one — and you’re done. You can now pick your business address in the From dropdown on any email.

This works, it’s free, and for a plumber emailing quotes to twenty local customers a month it is completely fine.

The catch: your mail is sent and cryptographically signed by Google as a gmail.com sender, not as yourbusiness.ca. The technical name is DMARC alignment, and yours won’t align. In practice, with no strict DMARC policy published on your domain, mail delivers normally. It only becomes a real problem if you later tighten your DMARC policy, or if you’re sending at volume to picky corporate mail servers.

Version 2 — the properly-aligned one. Route your outgoing mail through a transactional email service that lets you authenticate your own domain with DKIM — SMTP2GO, Brevo, Resend and Mailgun all have free tiers aimed at exactly this. You verify your domain with them, add the DKIM records they give you, then enter their SMTP server details in that same Gmail “Send mail as” box instead of Google’s.

Now your business mail is signed as yourbusiness.ca and aligns properly. It’s maybe 20 extra minutes and still $0.

Free-tier sending allowances on these services are usually generous for a small business but they change, and they’re often quoted per-day and per-month — check the current numbers on the provider’s own pricing page before you commit, rather than trusting any blog post, this one included.

Which version? Start with version 1. Move to version 2 when you’re sending enough that deliverability is worth 20 minutes — or immediately, if you enjoy doing things properly.

While you’re in the DNS: two records worth adding

Whichever version you pick, a domain that sends no mail and publishes no policy is an easy target for someone spoofing your business name.

• SPF — a TXT record naming who’s allowed to send as your domain. Whatever sending service you chose gives you the exact value.
• DMARC — a TXT record at _dmarc.yourbusiness.ca saying what to do with mail that fails. Start with the monitoring-only policy (p=none), which changes nothing about delivery and simply stops your domain being a blank cheque.

Both are copy-paste jobs, exactly like the paid setup.

Exactly where this breaks

Here’s the section everyone else leaves out. The free path is genuinely good, and it has a ceiling. You’ve hit it when:

The moment	Why free stops working	What to do
A second person needs the address	Forwarding lands in your personal inbox. There’s no shared account, no handover, no “check the info@ mail while I’m away.”	A real mailbox, one per person
You want the mail to live at your domain	Your business history sits inside a personal Gmail account. Nothing is stored at yourbusiness.ca.	A real mailbox
You want IMAP / a mail app on the business address	Forwarding has no server to connect to — there’s no account, just redirection.	A real mailbox
You start sending real volume	Free relay tiers are for a trickle. Newsletters and bulk sending are a different tool entirely.	A paid relay, or email-marketing software
You sell or hand over the business	You cannot hand someone your personal Gmail. The address was never separable from you.	A real mailbox, ideally from day one if you’re building to sell

Notice the pattern: every one of these is about the mailbox, not the address. That’s the same fork from the top of this page, and it’s why the fork is the only question that matters.

If two or more of those rows describe you, stop reading and go buy the dollar-a-month inbox. That’s not a defeat — it’s the tool matching the job, and a dollar is not the thing standing between you and a functioning business.

Canadians: the currency nobody mentions 🍁

There’s a quiet Canadian tax on cheap email that never appears in the sticker price.

Look at what happens on our comparison page: Google and Microsoft both charge Canadians more than a straight currency conversion of their US prices, and Zoho bills in US dollars — so a Canadian buying “a $1 plan” pays the conversion plus whatever foreign-transaction fee their card issuer adds, on a product priced at a dollar. The percentage overhead on tiny recurring USD charges is genuinely silly.

The $0 path sidesteps currency entirely, because zero converts perfectly. If you’re Canadian and torn between free and a dollar a month, that’s a real thumb on the scale — and it’s a point we’ve not seen made anywhere else, because the people writing about business email are being paid in the currency they’re quoting.

The receipt

Cloudflare Email Routing .............. $0
Gmail "Send mail as" .................. $0
SMTP relay free tier (optional) ....... $0
SPF + DMARC records ................... $0
Your time, once ....................... ~20 min

A paid mailbox, when you actually need one ... from about CA$1.40/mo (US$1)

That last line is not a grudging footnote. When you need a mailbox, buy one — here’s the comparison, and here’s the setup. The point of this guide isn’t that paid email is a scam. It’s that you shouldn’t buy one before you need it, and nobody else will tell you where that line is.
