+Mailomat Bridge
+===============
+
+Provides [Mailomat](https://mailomat.swiss) integration for Symfony Mailer.
+
+Mailer
+-------
+
+Configuration example:
+
+```env
+# .env.local
+
+# SMTP
+MAILER_DSN=mailomat+smtp://USERNAME:PASSWORD@default
+
+# API
+MAILER_DSN=mailomat+api://KEY@default
+```
+
+Where:
+ - `USERNAME` is your Mailomat SMTP username (must use your full email address)
+ - `PASSWORD` is your Mailomat SMTP password
+ - `KEY` is your Mailomat API key
+
+
+Webhook
+-------
+
+Create a route:
+
+```yaml
+framework:
+    webhook:
+        routing:
+            mailomat:
+                service: mailer.webhook.request_parser.mailomat
+                secret: '%env(WEBHOOK_MAILOMAT_SECRET)%'
+```
+
+The configuration:
+
+```env
+# .env.local
+
+WEBHOOK_MAILOMAT_SECRET=your-mailomat-webhook-secret
+```
+
+And a consumer:
+
+```php
+#[\Symfony\Component\RemoteEvent\Attribute\AsRemoteEventConsumer(name: 'mailomat')]
+class MailomatConsumer implements ConsumerInterface
+{
+    public function consume(AbstractMailerEvent $event): void
+    {
+        // your code
+    }
+}
+```
+
+Where:
+- `WEBHOOK_MAILOMAT_SECRET` is your Mailomat Webhook secret
