Email notification for subscription

[migmake]

Description

I would like to send an email confirmation when a user do a subscription.
I see in the doc how to do it with orders on products, but no informations about email on subscriptions...
Any ideas ?
Thanks.

Thanks for the request. We eventually plan to move subscriptions out of core Craft Commerce and let them live in payment provider plugins like our new Stripe plugin.

In the meantime you might be able to just do something like this in a module:

Event::on(
    Subscriptions::class,
    Subscriptions::EVENT_AFTER_CREATE_SUBSCRIPTION,
    function(SubscriptionEvent $event) {
        $mailer = Craft::$app->getMailer();
        /** @var Message $newEmail */
        $newEmail = Craft::createObject(['class' => $mailer->messageClass, 'mailer' => $mailer]);
        $newEmail->setTo($event->subscription->getSubscriber()->email);
        $newEmail->setSubject('Your new subscription');
        $newEmail->setHtmlBody('You have a new subscription');
        Craft::$app->getMailer()->send($newEmail)
     }
);
