How to Setup a Custom Email Provider for OTP emails

Custom Email Provider is a premium feature that allows developers to configure the sender of Magic Link emails by routing emails through their own SMTP servers. Emails sent from our servers come from the default [e-mail].
Enabling a custom SMTP gives you full control over where your application's login emails are sent from, as well as the name of the sender. Custom email providers are configured at the application level by visiting the Settings section of the Dashboard.
