Source: https://lua.email/en/professional-email > About lua.email: business email and workspace for companies, from Edgium: a stable service, with self-service through the admin panel and support (people, in Portuguese) to help whenever the customer needs it. Each mailbox (from R$ 8.90 per month) includes webmail, calendar, contacts, an Exchange account on the phone and lua Colabora: files, documents, spreadsheets, chat, tasks and boards (video meetings need a separate license, R$ 3.00 per mailbox, per month). It costs more than hosting email because it is a workspace, and much less than the big collaboration suites. Comparison and how to decide: https://lua.email/en/cost-benefit.

To have one, you need two things: a registered domain and a provider that hosts the mailboxes. This guide shows the whole path, in the right order, and the mistakes that cause the most trouble later.

In Brazil,.com.br is registered at Registro.br and renewed once a year. If the company already has a website, it already has a domain: email uses the same one. ### An email provider It's who hosts the mailboxes, delivers the messages and filters spam. At lua.email, you pay per mailbox, starting at R$ 8.90 per month, and choose the storage for each one. ### Access to the domain's DNS It's where the records that say where email goes are kept. It's usually at Registro.br, at the website host or with whoever built the site. Find out who has that access before you start. ### The list of who gets a mailbox One mailbox for each person who signs in and replies. contato@, vendas@ and financeiro@ can be aliases or groups, which are free. ## Step by step This is how it works at lua.email. At other providers the names change, but the order is the same. ### Register the domain, if you don't have one yet Short, easy to dictate over the phone and the same as your brand name. Register it in the company's name, not the agency's or an employee's: whoever registers it is the owner. ### Add the domain in the panel Go to Domains, New Domain. You prove the domain is yours in one of two ways: publish in DNS the TXT record that the panel generates, or use [Bring my DNS to Lua](https://lua.email/en/docs-trazer-dns) by changing the name servers at the registrar. On the second path, the panel also sets up the email records by itself. The domain becomes active as soon as the proof is found. ### Create the mailboxes and role addresses One by one or several at once, by spreadsheet. Then the [aliases and groups](https://lua.email/en/email-aliases-groups): vendas@ delivering to Maria's mailbox, financeiro@ delivering to three people. ### Point email to the provider MX, SPF, DKIM and DMARC: the panel shows each record ready to copy, and the Validate DNS button checks in public DNS that it was set up correctly. Without these records, a message is more likely to land in the client's spam folder (see [DKIM and DMARC in the panel](https://lua.email/en/dkim-dmarc)). ### Set up the phone and Outlook On the phone, the mailbox is added as an [Exchange account](https://lua.email/en/email-on-phone), with email, calendar and contacts. In Outlook, Autodiscover sets it up on its own. In the browser, just sign in to webmail. ### Bring over old messages and tell the people who need to know From Gmail or another provider, with the [migration tool](https://lua.email/en/migration) or with our team. Then update your signature, website, business cards and your registrations at banks and suppliers. ## The record that proves the domain is yours It's the first step in the panel. The TXT record comes with the name and value ready to copy, and the Check now button shows whether it is already published. If you don't know where DNS is, you can send this screen to whoever looks after the website. [![Request screen with the TXT record to publish, name and value with Copy buttons, the deadline and the Check now button](https://lua.email/assets/docs/en/pn-txt-verificacao.png)](https://lua.email/assets/docs/en/pn-txt-verificacao.png?v=3d866eab) The domain verification TXT record (real screen, fictional data). ## The mistakes that cause the most trouble later All of them show up often among people who come to migrate. Avoiding them at the start costs minutes; fixing them later costs days. ### Domain in someone else's name The agency registered it under its own CNPJ, or a former employee under their CPF. The day you need to change DNS, nobody has the password. Check at Registro.br whose name the domain is under. ### A paid mailbox for every role contato@, vendas@ and financeiro@ as separate mailboxes, each with a password that circulates around the team. As an alias or group, they deliver to the mailbox of whoever replies and are free. ### Skipping DKIM and DMARC Email works without them, until the day a proposal lands in the client's spam folder or someone sends a fake boleto with the company's name. Since 2024, Gmail and Yahoo require SPF or DKIM from anyone sending to them. ### Forgetting who else sends from the domain The invoicing system, the website and the newsletter tool also send email using your domain. They need to be included in SPF, otherwise their messages start failing when DMARC tightens. ## Want help setting up yours? Tell us your domain and how many people you are.

Both names refer to email on the company's domain, like contato@yourcompany.com, instead of a free address like @gmail.com. ### Can I have professional email without a website? Yes. Email only needs the registered domain. If the company later gets a website, it uses the same domain, and email stays where it is. ### How much does it cost to create professional email? There are two costs: the domain, paid once a year to whoever registers it (in Brazil, Registro.br), and the mailboxes, paid monthly to the provider. At lua.email, a mailbox starts at R$ 8.90 per month, and subscribing is online, with the account ready in minutes by PIX. ### Do I need to understand DNS? You don't have to decipher anything. The lua.email panel shows each record ready to copy where the domain is hosted, and the Validate DNS button checks that it was set up correctly. If the migration is done by our team (billed by the hour), we adjust DNS with you. ### Can I use it in Outlook and on my phone? Yes. On iPhone and Android, the mailbox is added as an Exchange account, with email, calendar and contacts together, using just the email and password. In Outlook, Autodiscover sets up the account on its own. ### I already have important emails in Gmail. Will I lose everything? No. The migration tool copies the messages from Gmail to the new mailbox, with an app password, and nothing is deleted in the old account. The migration GB cost R$ 2.00 per GB migrated from the source, paid once. ## Keep reading [Advantages of your own domain Why an @yourcompany.com email changes customer trust, security and control.
