# cPanel API 2 Functions - Email::listpopssingle

Warning:

The cPanel API 2 system is deprecated. We **strongly** recommend that you use [UAPI](/cpanel/introduction) instead of cPanel API 2.

## Description

Warning:

We **strongly** recommend that you use the following [UAPI](/cpanel/introduction/) function instead of this function:

- ` Email::list_pops ` — This function lists the cPanel account's email accounts.

cPanel Tag System (deprecated)

div
Warnings:
br
- cPanel tags are **deprecated**. We **strongly** recommend that you **only** use the [LiveAPI](/guides/guide-to-the-liveapi-system) system to call the cPanel APIs. Examples are **only** present in order to help developers move from the old cPanel tag system to our [LiveAPI](/guides/guide-to-the-liveapi-system).
- cPanel API 2 calls that use cPanel tags vary in code syntax and in their output.
- For more information, read our [Deprecated cPanel Tag Usage](/cpanel-api-2/cpanel-api-2-deprecate-cpanel-tag-usage/) documentation.
