## What it is
A Symfony bundle integrating the Swiftmailer library for sending emails in Symfony applications. It is no longer maintained because Swiftmailer itself is unmaintained since November 2021; users should migrate to Symfony Mailer.

## Use cases
- send emails from a Symfony app
- configure SMTP mail transport in Symfony
- integrate Swiftmailer with Symfony dependency injection
- maintain a legacy Symfony project using Swiftmailer
- migrate from Swiftmailer to Symfony Mailer

## When to choose
- you are maintaining an old Symfony application already built on Swiftmailer and cannot migrate yet

## When to avoid
- starting a new Symfony project
- you need maintained email sending with modern PHP and third-party provider support
- Swiftmailer is unmaintained and unpatched

## Facets
- artifact type: plugin
- maturity: abandoned
- function: email
- domain: email, web-development, backend
- platform: php
- tags: symfony-bundle, swiftmailer, deprecated, mailer
