Email (SendGrid)
Email is used for alerts, team invitations, password resets, and system notifications. InNEXTAUTH_PROVIDER="email" mode, the sign-in screen’s “Forgot password?” link sends the reset email through this same provider, so configuring it here is what enables self-service password recovery.
