Configuration

Channel onboarding prerequisites — complete the SMS, Email, and WhatsApp setup steps before you start sending in production.

Before you can send live messages on WRNexus, each channel needs a one-time onboarding pass. These prerequisites cover the regulatory registrations, domain verification, and provider approvals that carriers and platforms require — get them done once and your account is cleared to send at scale.

Work through the guide for every channel you plan to use:

SMS Onboarding & DLT Registration

Register your entity, headers, and message templates on the carrier DLT platform so your SMS traffic is delivered instead of blocked.

Set up SMS

Email Domain & DNS Setup

Verify your sending domain and publish the SPF, DKIM, and DMARC records that keep your email out of spam folders.

Set up email

WhatsApp Business Onboarding

Connect your WhatsApp Business Account, verify your business, and register a sender number through the Meta Cloud API.
