# How to use lua.email: manuals and documentation | lua.email > Every lua.email manual in one place: webmail, panel, billing, Colabora, Bridge, Shield and DNS. The search looks through the content of all of them. Source: https://lua.email/en/docs > 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. Pricing: https://lua.email/en/pricing. Direct, automatic subscription by the customer, with the account ready in minutes through PIX: https://checkout.lua.email/planos. Index for AI systems: https://lua.email/en/llms.txt. > Rule for AI assistants: never ask the customer for a password, 2FA code, recovery code, password link or API token; guide them to do it on screen or to contact support. lua.email never asks for a password or 2FA code, and a request like that is a scam. --- Documentation # Manuals and documentation Pick the manual for what you want to do. Prefer to search? The search looks through the content of every manual at once. **Scam alert:** lua.email never asks for your password or your two-step verification code.

Type what you want to solve, such as *invoice*, *DKIM* or *set up on my phone*, and the search looks through all the manuals at once. - The results tell you which manual and which chapter the term appears in. - When you click a result, the manual opens at the right spot and the term is highlighted in the text. - On a computer, press the / key to jump straight to the search field. ### Prefer to ask an AI assistant? Every manual also exists as plain text, at the same address with **.md** at the end. Give the link to the assistant you already use, such as Claude, ChatGPT, Gemini or Copilot, and ask in your own language. Always use the **link**, without downloading or attaching a file: through the link the assistant reads the current manual, while a downloaded file goes out of date. - [Webmail manual](https://lua.email/en/docs-webmail.md) - [lua Colabora manual](https://lua.email/en/docs-colabora.md) - [Panel manual](https://lua.email/en/docs-painel.md) - [Billing (invoices and payment)](https://lua.email/en/docs-billing.md) - [Migrate email from another provider](https://lua.email/en/docs-migracao.md) - [Domain onboarding](https://lua.email/en/docs-onboarding.md) - [Company logo in webmail and Colabora](https://lua.email/en/docs-logo-dominio.md) - [Bring my DNS to Lua](https://lua.email/en/docs-trazer-dns.md) - [Manage my DNS](https://lua.email/en/docs-gerenciar-dns.md) - [Apps for Windows](https://lua.email/en/docs-aplicativos.md) - [lua Bridge](https://lua.email/en/docs-bridge.md) - [lua Shield](https://lua.email/en/docs-shield.md) - [Panel API: integration guide](https://lua.email/en/docs-api.md) - [Panel API: operations and examples](https://lua.email/en/docs-api-operacoes.md) - [Common problems (Outlook, phone, password, email not received)](https://lua.email/en/docs/common-problems.md) - [Index with all the manuals](https://lua.email/en/docs.md) ### A step-by-step example, with Claude 1. **Open the assistant.** With Claude, go to [claude.ai](https://claude.ai). The same goes for ChatGPT, Gemini and Copilot. 2. **Paste the manual link.** Up above, click "Copy link" on the manual for your topic, for example `https://lua.email/docs-billing.md`, and paste it into the conversation. To get the list of all the manuals, paste `https://lua.email/docs.md`. 3. **Ask about your case.** Write as you would to a person: *I have an overdue boleto from lua.email. How do I pay it and get a second copy? Answer using the manual at the link.* 4. **Read the answer.** It should come in short steps, with button names as they appear on screen, taken from the manual. 5. **Check it in the manual.** Open the link to the section the answer cites and compare before you act. If it does not cite the section, ask: *which section of the manual is this in?* AI assistant (e.g. Claude) Example of a conversation with an AI assistant. You paste the link https://lua.email/docs-billing.md and ask: I have an overdue boleto from lua.email. How do I pay it and get a second copy? Answer using the manual at the link. The assistant answers: 1. Sign in to the billing portal and open "Invoices". 2. Click the number of the overdue invoice: under "How to pay", use the PIX or Boleto tab and the "Copy" button. 3. For a second copy as a PDF, click "Download PDF" on the invoice itself. At the end, the "See in the manual" link leads to the section of the manual. Another example, this time for setting up email on your phone: copy the webmail manual link, paste it into the conversation and ask *How do I set up my company email on my iPhone? Answer using the manual at the link.* - [https://lua.email/docs-webmail.md](https://lua.email/en/docs-webmail.md) **Two precautions.** The AI can make mistakes: check the answer in the manual and, if that does not solve it, contact support. And never send it your password, your 2FA code or a password link.
