Combining SMS and WhatsApp messaging channels in Salesforce offers businesses a comprehensive way to reach and engage customers. For Salesforce users, admins, and marketing professionals, it is essential to implement these communication methods while adhering to legal compliance and communication best practices. This blog focuses on how to achieve compliant, effective multi-channel messaging using Message Blink, a 100% native best Salesforce messaging app, to send sms from salesforce.

Understanding Compliance Requirements for SMS and WhatsApp Messaging

TCPA and SMS Regulations in the US

The Telephone Consumer Protection Act (TCPA) establishes strict rules for SMS marketing to protect consumers from unwanted communications. Businesses must obtain prior express written consent before sending promotional SMS. They also need to provide clear opt-out instructions in every message and respect timing restrictions for sending texts. Non-compliance can lead to heavy penalties and impact your Salesforce SMS campaigns.

WhatsApp Business Messaging Policies

WhatsApp requires businesses using the WhatsApp Business API to:

  • Obtain explicit user consent before messaging.

  • Use only pre-approved message templates for outbound communications.

  • Respect opt-out requests promptly.

  • Keep conversational threads professional and relevant.

Businesses that fail to meet WhatsApp’s rules risk loss of access to the WhatsApp Business API and related messaging services.

Salesforce’s Compliance Framework

Within Salesforce, compliance can be managed through data capture, automation, and logging. Salesforce admins and developers can use custom fields to record opt-in status, and automate compliance checks using Flows or Process Builder. This framework paired with a messaging platform like Message Blink helps maintain compliance at scale.

1. Collecting and Tracking Opt-Ins

Capture customer consent explicitly through Salesforce forms, purchase journeys, or support interactions. Record this consent on Lead and Contact records in Salesforce to create a single source of truth across SMS and WhatsApp channels.

2. Unified Opt-In Management with Message Blink

Message Blink, as a Meta tech provider, integrates natively with Salesforce to provide unified opt-in tracking across both SMS and WhatsApp. This prevents sending messages to unsubscribed users or numbers that have opted out on either channel.

3.Maintaining Customer Preferences

Use automated Salesforce workflows to manage re-opt-in campaigns, reminding customers of message preferences or requesting consent renewal to stay compliant with evolving regulations.

Crafting Compliant and Engaging Messages

WhatsApp Message Templates

Utilize WhatsApp-approved message templates stored and managed in Salesforce through Message Blink. Avoid overly promotional content, keep templates informative, and personalize dynamically with Salesforce data.

Best Practices for SMS Content

  • Be concise, clear, and relevant.

  • Include standard opt-out instructions like “Reply STOP to unsubscribe.”

  • Avoid spammy language and excessive use of links.

  • Time message sends thoughtfully respecting customer time zones.

Personalization to Enhance Engagement

Leverage Salesforce data to customize messages by customer behavior, preferences, and interactions. This approach increases engagement while adhering to compliance by making messages meaningful and welcomed.

Automating Compliance with Salesforce and Message Blink

1. Automated Opt-In Checks

Configure Salesforce automation to confirm opt-in status before any outbound SMS or WhatsApp sends. Message Blink supports these checks and ensures messages are only sent to compliant contacts.

2. Scheduling of Messaging
