## What it is
Nextcloud Mail is a webmail client app for Nextcloud that connects to any IMAP/SMTP account, built on the Horde PHP libraries with a Vue single-page frontend. It integrates with Nextcloud Contacts, Calendar, Files, and Tasks, and supports S/MIME and Mailvelope encryption.

## Use cases
- access my email inside nextcloud
- self-hosted webmail client for imap accounts
- manage multiple mail accounts with a unified inbox
- send encrypted email with s/mime or pgp
- replace gmail with a self-hosted mail interface
- group emails into conversation threads
- host my own email client without a mail server

## When to choose
- you already run Nextcloud and want integrated email with Contacts/Calendar/Files
- you need a self-hosted webmail UI for existing IMAP/SMTP servers
- you want multi-account unified inbox with encryption support

## When to avoid
- you need a full mail server - this is a client, pair it with Mail-in-a-Box, Stalwart, or Dovecot
- you don't use Nextcloud and want a standalone webmail like Roundcube or SnappyMail
- you need heavy offline desktop email features like Thunderbird
