How to auto subscribe customer in registration process?

Question

There is a code for checked newsletter subscription in Magento 2 registration page like below.

Even if I click on the checkbox and register the newsletter subscription is not working as shown below.

Answer 1

In Magento customer account create post page the code looks like below:

    if ($this->getRequest()->getParam('is_subscribed', false)) {
        $this->subscriberFactory->create()->subscribeCustomerById($customer->getId());
    }

If you see the data is posted correctly then you should look for the custom extensions which might be modifying the behavior of the method.

NOTE: This will not instantly subscribe the customer, he has to verify his mail first, depending on how you set it up in the settings at Store -> Configuration -> Customer -> Newsletter: Abonnement options -> Has to confirm.

So if the above method does not instantly subscribe, then check your mails and settings.
