symfony/mailer

If the project contains .ddev/config.yaml, prefix every shell command with ddev (full mapping in the symfony skill's references/ddev.md). Examples target Symfony 7.4, 8.0 and newer — verify the installed version before using newer features.

When to use

You need to send email — transactional notifications, password resets, digest emails, etc. Supports SMTP, plus transports for SendGrid, Mailgun, Postmark, SES, Brevo, and others.

Replaces

PHPMailer
SwiftMailer (EOL)
Vendor SDKs called purely to send mail (SendGrid, Mailgun PHP SDK, etc.)
Raw mail() calls

Install

composer require symfony/mailer
# transport bridges (pick one):
composer require symfony/sendgrid-mailer
composer require symfony/mailgun-mailer
composer require symfony/amazon-mailer

Set MAILER_DSN in .env (e.g., sendgrid+api://KEY@default).

Minimal example

php

use Symfony\Bridge\Twig\Mime\TemplatedEmail;
use Symfony\Component\Mailer\MailerInterface;

public function __construct(private MailerInterface $mailer) {}

public function sendWelcome(string $to): void
{
    $email = (new TemplatedEmail())
        ->from('noreply@example.com')
        ->to($to)
        ->subject('Welcome!')
        ->htmlTemplate('emails/welcome.html.twig')
        ->context(['user' => $to]);

    $this->mailer->send($email);
}

Common patterns

Plain `Email` (no Twig)

php

use Symfony\Component\Mime\Email;

$email = (new Email())
    ->from('noreply@example.com')
    ->to('alice@example.com')
    ->subject('Receipt')
    ->text('Plain body')
    ->html('<p>HTML body</p>');

$this->mailer->send($email);

Attachments

php

$email->attachFromPath('/path/to/invoice.pdf', 'invoice.pdf', 'application/pdf');
// or inline:
$email->embedFromPath('/path/to/logo.png', 'logo');
// reference in template as <img src="cid:logo">

Async via Messenger (recommended for any user-facing flow)

In Flex projects MAILER_DSN is wired through Messenger automatically if a messenger.transport.async is configured. Otherwise:

yaml

# config/packages/messenger.yaml
framework:
    messenger:
        transports:
            async: '%env(MESSENGER_TRANSPORT_DSN)%'
        routing:
            'Symfony\Component\Mailer\Messenger\SendEmailMessage': async

The mailer then enqueues SendEmailMessage; a worker consumes and sends.

Multiple mailer transports

yaml

framework:
    mailer:
        transports:
            main: '%env(MAILER_DSN)%'
            newsletter: '%env(NEWSLETTER_DSN)%'

Pick at send time:

php

$email->getHeaders()->addTextHeader('X-Transport', 'newsletter');

Gotchas

TemplatedEmail requires symfony/twig-bundle.
from() is mandatory; configure a project-wide default via

framework.mailer.envelope to avoid setting it everywhere.

In dev, use MAILER_DSN=null://null to swallow mail, or point at

Mailpit/MailHog for inspection. ddev bundles Mailpit by default — see the symfony skill's references/ddev.md for the DSN and how to open its UI.

For DKIM/SPF you must configure the transport's account — Symfony just

hands the message off.
