SMS Campaigns for WHMCS

Reach your clients instantly with mass SMS campaigns from inside WHMCS. SMS Campaigns lets you target groups of clients, send messages through Twilio, and track delivery without leaving the admin area.

Whether you need a one-off reminder or a campaign to thousands of customers, this module queues messages and sends them automatically with the WHMCS cron.

Why SMS Campaigns?

Email is easy to miss. SMS is read. Use this module to notify clients about outages, promotions, renewals, or account updates using the phone numbers already stored in WHMCS.

Key benefits:

  • Send bulk SMS to filtered groups of WHMCS clients
  • Send a single SMS instantly when you need a one-off message
  • Track sent, failed, and pending messages per campaign
  • Retry failed SMS without recreating the campaign
  • Works with your existing Twilio account

Features

Mass Campaign Builder

Create campaigns in a simple two-step wizard:

  1. Choose recipients — General clients, Product/Service, Addon, or Domain
  2. Compose and send — Write your message and launch the campaign

Filter by client group, status, country, language, custom fields, products, servers, and domain status so only the right clients receive the message.

Campaign Dashboard

Manage campaigns from a familiar WHMCS-style list:

  • Campaign name and type (General, Product/Service, Addon, or Domain)
  • Status: In Progress, Completed, Paused, or Pending
  • Sending progress such as 6808 / 6882 (99%)
  • Start and completed date/time based on actual sending activity
  • Pause, resume, delete, and preview the message

Sending Report

Open View Sending Report to see:

  • Total messages sent
  • Failed deliveries with client name and failure reason
  • A Retry button that sends that SMS immediately via Twilio

Manual SMS

Send a one-off SMS to any number from the Send SMS page. Select the country, enter the number, and send. Useful for support follow-ups and quick notices.

SMS Logs

Review request and response logs for campaign and manual sends. Logging is designed to stay fast even with large volumes of records.

Twilio Integration

Connect your Twilio account in Settings:

  • Account SID
  • Auth Token
  • From Number
  • Client phone number source (WHMCS profile field or a custom field)
  • Optional message signature

How It Works

  1. Enter your Twilio credentials in Settings.
  2. Create a campaign and select the client group to target.
  3. Compose the SMS and start the campaign.
  4. WHMCS cron sends queued messages in batches through Twilio.
  5. Review progress, failed messages, and retry as needed.

Requirements

  • WHMCS 8.x
  • PHP 7.4 or later
  • A Twilio account with SMS capability
  • WHMCS system cron enabled

A Twilio account is required. SMS usage is billed by Twilio according to your Twilio plan.
