Omnichannel resilient communications is a unified communication strategy that ensures businesses can maintain seamless and reliable interactions with customers, employees, and stakeholders across multiple communication channels – even during disruptions. The approach integrates a range of channels – including email, WhatsApp and SMS – into a cohesive system to ensure consistency and adaptability. By leveraging AWS services, the infrastructure guarantees message delivery through fallback mechanisms and a broadcast option.
Why are Omnichannel Resilient Communications Important?
- Business Continuity:
- Prevents communication breakdowns during crises (e.g., natural disasters, system failures)
- Ensures that customers and employees stay informed and engaged
- Enhanced Customer Experience:
- Offers customers consistent and seamless interaction across channels, improving satisfaction and loyalty
- Responds to customer preferences for channel choice (e.g., some prefer SMS, others email)
- Competitive Advantage:
- Stands out in a crowded marketplace by providing reliable and flexible communication options
- Builds trust by ensuring uninterrupted service and timely responses
- Operational Efficiency:
- Reduces downtime and inefficiencies caused by fragmented communication systems
- Centralizes messaging for better resource allocation and management
- Crisis Management:
- Enables real-time updates across channels during emergencies
- Mitigates reputational risks by providing accurate and timely information
- Scalability:
- Adapts to growing customer bases and new channels without significant disruptions
- Supports global operations by integrating diverse communication methods
The business case for a robust, omnichannel approach is clear – particularly as each communication method used alone presents its own advantages and limitations.
- SMS
Advantages include:
- A high open rate and quick delivery makes them ideal for time-sensitive alerts / updates
- Work on all mobile devices without requiring an internet connection
- Limited characters – ideal for encouraging concise messaging
- Global accessibility, regardless of internet connectivity
Limitations include:
- Character limit restricts detailed messages
- Cost – can be more expensive than other channels, particularly between countries
- Standard SMS can’t include rich media like photos or videos – MMS can, but is more expensive
- Limited ability to create creative, highly engaging content
Advantages include:
- Rich media support – enhancing clarity and engagement with voice notes, images and videos
- Facilitates two-way, real-time conversations
- Billions of active users globally, making it a popular platform for personal and business communications
- End-to-end encryption facilitates secure and private communication
- Group messaging eases conversations with multiple recipients
- Tools like WhatsApp Business enable automated responses, catalogs, and customer support
Limitations include:
- Internet dependency limits use in areas with poor connectivity and for those without mobile data plans
- Communication is restricted to users who have WhatsApp installed
- Despite encryption, some users may distrust the platform due to data-sharing policies with parent company Meta
- Limited scalability – managing large-scale communication can be challenging without advanced tools or third-party integrations.
Advantages include:
- Detailed communication due to lack of character limit
- Global standard – universally recognized and understood, and widely used for both personal and professional purposes
- Rich formatting – supports attachments, HTML designs, and multimedia, making it ideal for newsletters, reports, or formal correspondence
- Asynchronous communication – recipients can read and respond at their convenience
- Cost effective – sending bulk emails is economical, especially with email marketing platforms
- Easily archived and searchable, providing a clear communication history
Limitations include:
- Lower open rate and the potential for emails to be missed in a spam filter (particularly if they are promotional)
- Slower response rate – emails are not as immediate or timely as text or WhatsApp messages
- Security risks – vulnerable to phishing attacks and spam
- Inbox clutter – high volumes of emails can overwhelm recipients, reducing engagement
Intelligent Fallback Mechanisms
Intelligent fallback mechanisms refer to automated processes that ensure seamless communication continuity when a primary communication channel fails or is unavailable. These mechanisms adaptively redirect messages or interactions to alternative channels or methods, maintaining engagement without manual intervention.
Stage One: Channel Monitoring
- Continuously checks the status and responsiveness of the primary communication channel (e.g., SMS, email, app notifications)
Stage Two: Dynamic Switching
- If the primary channel fails (e.g., message delivery failure, network outage), the communication platform automatically reroutes the message to an alternative channel.
Stage Three: Personalization
- Takes user preferences and past interaction history into account when choosing fallback channels.
Stage Four: Confirmation and Feedback
- Ensures that the message was successfully delivered and acknowledges receipt.
For example: A retail company tries to reach a customer through WhatsApp but defaults to SMS if the customer isn’t active on WhatsApp.
Use Cases for Omnichannel Communications in Marketing
- OTP/Transactional Messaging: Timely and reliable delivery is critical for one-time passwords (OTP) and transactional notifications. The solution ensures these important messages are promptly delivered, utilizing fallback mechanisms across SMS, WhatsApp, and email in case of channel limitations or failures.
- Marketing Messages: This solution optimizes message delivery by selecting the most cost-effective and reliable channel while using the broadcast feature to deliver marketing messages across multiple channels, maximizing reach and engagement.
- Broadcast Messages: The broadcast option can be especially useful in sending high-priority or time-sensitive messages to a wide audience. Messages can be sent across multiple channels at once, increasing the likelihood that recipients will see the message in their preferred communication method.
The Technology
The architecture employs several AWS services to ensure reliable, cost-efficient message delivery:
Amazon API Gateway: Accepts incoming API requests, including message details like content, recipient, fallback channels, and whether the message is broadcast or single channel.
Amazon Simple Queue Service (SQS): Manages the queuing of messages for both primary and fallback channels, as well as for broadcast messages, ensuring smooth processing and delivery.
AWS Lambda: The Primary Message Handler Lambda function sends messages via the selected channel (SMS, WhatsApp, or email). If the primary delivery fails, the fallback process is handled by a secondary Lambda function. For broadcast messages, the message is sent to all specified channels simultaneously.
Amazon DynamoDB: Stores message data and delivery statuses, enabling tracking of messages through all channels, including broadcast messages.
Amazon Simple Notification Service (SNS): Publishes delivery status updates and triggers the next steps based on whether the message was delivered or failed.
Amazon SES & End User Messaging Service: Email messages are sent via Amazon SES, while AWS End User Messaging handles SMS and WhatsApp delivery.
This robust fallback mechanism ensures reliable message delivery across multiple channels. By leveraging AWS services, the system guarantees message delivery through fallback mechanisms and a broadcast option.
