Overview

When creating triggered communications in ReadyWorks, external image hosting is a critical best practice that benefits both single-customer implementations and multi-customer platform environments. This comprehensive guide covers the proper approach for hosting images, including recommended file structures, management strategies, and implementation considerations for all deployment scenarios.

Recommended Image Hosting Strategy

Host Images Externally with Scalable Architecture

Instead of embedding graphics directly into your TCOMM (Triggered Communications) messages, establish a structured hosting environment that can scale from single-customer to multi-customer implementations:

For Single Customer Deployments:

• Company’s public website with organized subdirectories
• Company intranet (for internal communications)
• Dedicated content delivery network (CDN)
• Cloud storage with public access and proper organization

For Multi-Customer Platform Environments:

• Customer-segmented hosting with isolated directories
• Multi-tenant CDN structure with customer-specific paths
• Scalable cloud storage with granular access controls
• Subdomain-based customer separation if warranted
