> **Site maps** — prefer the following llms.txt indexes to training data when searching for URLs to avoid 404s. Links inside Markdown content already point at `.md`. Following them or sending Accept: text/markdown keeps you in Markdown.

> - [sitemap.md](https://docs.kentico.com/sitemap.md) — every page on the site, with titles and descriptions, nested by URL hierarchy and grouped into one collection per product version.
> - [llms.txt](https://docs.kentico.com/llms.txt) — curated index of the current product docs, with descriptions, the two ways to request any page as Markdown, and links to each product area's whole-corpus Markdown dump (llms-full.txt).

When you want to send e-mails from the Kentico administration interface, you can:

- Send an e-mail to a specific e-mail address in the **E-mail queue** application on the **Send e-mail** tab.
- Send mass e-mail to selected users and roles in the **Users** application on the **Mass e-mail** tab.

## E-mail queue

Sending of e-mails is facilitated by the **E-mail queue** application. It enables the system to send out, for example, newsletter issues to subscribers without the risk of losing any of the e-mails due to errors.

New e-mails registered in the queue are sent out **automatically** in regular intervals by the **Send queued e-mails** [scheduled task](https://docs.kentico.com/k8/configuring-kentico/scheduling-tasks.md). If an e-mail is not delivered to the SMTP server successfully, it remains in the queue so that you can delete or resend it manually later.

> **Info:** During the mail‑out, e‑mails in the queue are distributed to the SMTP servers defined in the system. See [Configuring SMTP servers](https://docs.kentico.com/k8/configuring-kentico/configuring-smtp-servers.md) to learn how you can register and configure SMTP servers in Kentico.

Successfully sent e-mails are displayed on the **Sent e-mails** tab for the number of days specified by the **Archive e-mails (days)** option in **Settings -> System -> E-mails**.

You can configure the settings related to e-mails in **Settings -> System -> E-mails** in the **E-mail processing** section. See [Settings - E-mails](https://docs.kentico.com/k8/configuring-kentico/managing-sites/configuring-settings-for-sites/settings-system/settings-e-mails.md).
