# Customization

The section **Customization** defines the brand under which the service is presented. 

It has two surfaces that you customize separately, the **User portal** (what the end customer uses) and the **Administration panel**, plus the email configuration. 

The reason for all this is in [The end customer and the partner brand](https://claude.ai/chat/el-cliente-final-y-la-marca).

### User portal and administration panel

Both surfaces are configured with the same elements:

| Item                        | What it is                                                                                                                                                                                                   |
| --------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| Portal name and Description | The portal name and description.                                                                                                                                                                             |
| Visual identity             | Background image (with View Gallery), Logo, Favicon, and Colors (Primary color, in format `#hex`).                                                                                                           |
| Own domain                  | A URL field for your address and, below it, the CNAME block with the HOST · TYPE · VALUE table. You need to create that CNAME record for the new URL to work. A Reset button returns to the default address. |
| Certificate                 | Choose between Generate Let's Encrypt certificate or Upload my own certificate.                                                                                                                              |

You save each block with **Save** (or discard with **Cancel**).

### Email

Define how and what the emails sent to the end customer look like. You can click **Send test email** to check it.

**Sending mode:**

* Use the established email template.
* Send from a specific email account (through our mail servers). When you choose it, you specify the sending email address and the display name.

**Appearance of sent emails:**

* Use the established email template.
* Custom: you define the organization name, the Logo, the Colors (Primary), and the email signature.

> #### ❗️ **Enable SPF and DKIM** 
>
> For emails to arrive correctly with your own account, SPF and DKIM must be enabled. 
>
> After completing and submitting the form, you will receive the instructions to do it.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.plenit.com/docs-en/platform/organizations/detalles/customization.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
