How to re-enable email notifications

Discord should allow the email notification function to be turned back on. I made a fast decision to tunrof email notofocations. This is normal, people often make fast decisions and then change their mind later.
Also I didn't know that clicking it is permanent and cannot be undone

otherwise I would have been more careful.

Considering that many other sites have easy way to re enable this setting

I don't see why it should take this long to add this feature.

Please add this feature ASAP..
