Free business email in Brazil: set up name@yourbusiness.com.br

Millions of Brazilian MEIs and small companies sell through WhatsApp, Mercado Livre and Instagram, take Pix, and use a Gmail for everything else. If you are ready for contato@suaempresa.com.br, the good news is that Brazil's domain system is straightforward and the mailboxes can be free. Here is the setup end to end.

Quick answer

Register suaempresa.com.br at Registro.br using your CPF or CNPJ, create a free OquMail workspace, add the domain, paste four DNS records, create mailboxes. The email is free with no card and no per-user fee, so the domain is the only cost.

Domain choice: .com.br or .com

Brazilian domains are run by Registro.br. A .com.br (and the other .br endings) requires a CPF for individuals or a CNPJ for companies, which means every .com.br is tied to a real Brazilian taxpayer. Registration is done directly at Registro.br or through resellers such as HostGator Brasil and Locaweb. A .com is common among Brazilian tech companies and exporters, but Brazilian consumers strongly expect .com.br.

• .com.br: requires CPF or CNPJ; the standard for Brazilian businesses of any size
• .net.br and .art.br: alternatives for tech and creative businesses
• .com: fine for exporters and software companies; still recognised locally
• MEIs can register with their CPF or the MEI CNPJ; using the CNPJ keeps the domain with the business

Why Brazilian customers trust a .com.br address

Because .com.br is tied to a CPF or CNPJ, an email from financeiro@suaempresa.com.br signals a registered business. That matters for issuing NF-e invoices, for quoting condominiums and companies, for Mercado Livre sellers moving to B2B, and for any dealing with banks. A Gmail address on a boleto or invoice is a well-known fraud pattern that Brazilian accounts departments have learned to question.

Step by step

1. Register suaempresa.com.br at Registro.br with your CPF or CNPJ, or through a reseller.
2. Create a free OquMail workspace at oqumail.com. No card.
3. Add the domain in the dashboard and copy the four DNS records.
4. At Registro.br, open the domain, choose Editar zona (DNS) and add the MX, SPF, DKIM and DMARC records. At a reseller, use its DNS panel.
5. Click Verify. The live DNS check shows which record is still missing.
6. Create mailboxes: contato@, financeiro@, vendas@ and one per person, up to 15.
7. Send a test from webmail, then add the account to Outlook or the phone mail app with the settings below.

The four DNS records OquMail needs

Registro.br's own DNS editor accepts MX and TXT records directly. If your domain was set up by a hosting reseller, that reseller probably pre-set an MX for its webmail; delete it before adding OquMail's.

• MX — host @, value mail.oqumail.com, priority 10
• SPF (TXT at @) — v=spf1 MX (Mail Exchanger — where incoming email is delivered) a:mail.oqumail.com ~all
• DKIM (TXT at your selector ._domainkey) — v=DKIM1; k=rsa; p=… (the exact key is shown in your OquMail dashboard)
• DMARC (TXT at _dmarc) — v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com

OquMail connection settings

• Incoming (IMAP): mail.oqumail.com, port 993, SSL/TLS
• Outgoing (SMTP): mail.oqumail.com, port 587, STARTTLS
• Username: your full email address (you@yourdomain.com)
• Password: the same password you use for OquMail webmail

What it costs

The domain is a yearly fee at Registro.br, payable by boleto or Pix. The email is free: OquMail's free plan needs no card and includes 15 mailboxes, 3 domains, 5 GB per mailbox, webmail, IMAP/SMTP, delivery logs and a send API. For an MEI or a small company, that removes the per-user monthly charge of Google Workspace or Microsoft 365 entirely.

Pitfalls common in Brazil

• Bundled hosting email with no DKIM: NF-e and orçamento emails land in spam at Gmail and Outlook.
• Vivo, Claro and TIM connections block outbound port 25. Use port 587 with STARTTLS.
• Choosing SSL on port 587 in Outlook. It must be STARTTLS.
• Accented mailbox names. Keep addresses plain ASCII (joao@, not an accented form) and put the full name in the display name.
• Leaving the Gmail on your Mercado Livre account and Google Business Profile after the domain is live.

Common questions

Can an MEI register .com.br?

Yes, with the MEI CNPJ or your CPF. Registering with the CNPJ is better because the domain stays with the business if you later change structure.

Does it work with Outlook and my phone?

Yes. Add an IMAP account in Outlook, Apple Mail or the Gmail app with the settings above.

What are the limits?

15 mailboxes, 3 domains, 5 GB per mailbox, no expiry.
