 The Send Email Hook runs before an email is sent and allows for flexibility around email sending. You can use this hook to configure a back-up email provider or add internationalization to your emails.
 
+## Email Sending Behavior
+
+Email sending depends on two settings: Email Provider and Auth Hook status.
+
+| Email Provider | Auth Hook | Result                                                               |
+| -------------- | --------- | -------------------------------------------------------------------- |
+| Enabled        | Enabled   | Auth Hook handles email sending (SMTP not used)                      |
+| Enabled        | Disabled  | SMTP handles email sending (custom if configured, default otherwise) |
+| Disabled       | Enabled   | Email Signups Disabled                                               |
