## What it is
PHPMailer is a full-featured PHP library for creating and sending email, with integrated SMTP support, authentication, attachments, HTML/multipart messages, and DKIM/S/MIME signing. It is the classic, widely adopted email-sending class used by projects like WordPress, Drupal, and Joomla.

- send emails without a local mail server

- send multipart alternative emails from php

## When to choose
- you need reliable RFC-compliant email sending from PHP
- you need SMTP auth, TLS, attachments, or HTML email support
- you want battle-tested code protecting against header injection

## When to avoid
