We’re thrilled to announce the release of FlowMattic 5.4.0, our most powerful update yet! This release introduces game-changing features that will transform how you build, manage, and scale your WordPress automation workflows. From modular sub-workflows to advanced email monitoring and intelligent image compression, version 5.4.0 is packed with tools designed to save you time and amplify your productivity.

Let’s dive into what’s new and how these features can revolutionize your automation strategy.

🚀 Major New Features in FlowMattic 5.4.0

1. Sub-Workflows: Build Modular, Reusable Automation

One of the most requested features is finally here! Sub-Workflows allow you to create modular, reusable workflow components that can be called from other workflows with full parameter passing support.

Why this matters:

DRY Principle: Don’t repeat yourself. Create a workflow once, use it everywhere
Easier Maintenance: Update logic in one place and it automatically reflects across all parent workflows
Complex Logic Simplified: Break down complicated automations into manageable, testable pieces
Circular Dependency Detection: Built-in safeguards prevent infinite loops and workflow conflicts

Use Case Example: Create a “Send Welcome Email” sub-workflow that can be triggered from multiple parent workflows (new user registration, course enrollment, membership upgrade) with customized parameters for each scenario.

2. IMAP Email Parser: Monitor Email Accounts Like Never Before

Move beyond simple email forwarding! The new IMAP Email Parser gives you direct access to monitor any IMAP-compatible email account with powerful filtering capabilities.

Key Features:

Connect to Gmail, Outlook, Yahoo Mail, or any IMAP server
Advanced filtering by sender, subject, date, and content
Automatic attachment import to WordPress media library
Parse email content with full HTML support
Real-time monitoring without third-party services

Use Case Example: Automatically create support tickets from customer emails, import invoice PDFs from supplier emails, or trigger order fulfillment workflows when shipping notifications arrive.

3. CSV Creator: Export Data Your Way

Transform your FlowMattic tables, JSON data, or arrays into professional CSV files with the new CSV Creator module.

Features:

Create CSV files from FlowMattic tables with custom WHERE queries
Convert JSON data or arrays to CSV format
Auto-save to WordPress media library for easy access
Perfect for reports, exports, and data migration

Use Case Example: Generate daily sales reports, export customer lists for email campaigns, or create inventory snapshots for accounting purposes.

Speed up your site and save storage space with intelligent Image Compression built right into your workflows.

Benefits:

Configurable quality settings for perfect balance between size and clarity
Support for multiple image formats (JPEG, PNG, WebP)
Auto-save compressed images to media library
Powered by FlowMattic API for reliable compression

Use Case Example: Automatically compress user-uploaded images, optimize product photos from suppliers, or batch process media library images during off-peak hours.

Email Template Builder: Dynamic Content with Loop Block

Create professional, data-driven emails with the new Loop Block in the Email Template Builder. This powerful feature lets you iterate over dynamic data arrays to generate repetitive content automatically—perfect for invoices, product catalogs, order confirmations, and blog digests.

The Loop block seamlessly integrates with FlowMattic’s data processing capabilities, allowing you to transform API responses, database queries, and CSV data into beautifully formatted email content.

Webhook Response: XML Support for VoIP and API Integrations

Integrate FlowMattic with VoIP services, telephony APIs, and other XML-based systems using the new XML Response feature in the Webhook Response module.

Two Response Modes:

Parameters as XML: Automatically converts key-value pairs to properly formatted, valid XML with nested structure support

Technical Features:

WordPress Posts List: Quick Testing with Manual Trigger Links

Speed up your workflow development with Manual Trigger Links directly in the WordPress posts list. Test “New Post” and “Update Post” workflows instantly from any post in your posts table—no need to actually create or update posts.

Benefits:

Faster Testing: Click and test workflows directly from the posts table
Works with All Post Types: Custom post types, pages, WooCommerce products—everything
No Data Changes: Test workflows without modifying actual post data
Real Context: Use actual post data for accurate workflow testing

How It Works:

Look for the “Test New Post Workflow” and “Test Update Post Workflow” links in the row actions of each post. Click to trigger your workflows with that specific post’s data—perfect for debugging and validation without cluttering your workflow task history with dummy test data.

This feature significantly reduces the time spent on workflow development and testing, especially when working with content-heavy sites or complex post types.

Date Time Formatter: Now More Powerful Than Ever

The Date Time Formatter module receives a massive upgrade with seven new actions:

WordPress Default and Custom Formats: 4 new time format presets
Parse Date Action: Extract year, month, day, hour, week number, quarter, and more
Check Date Condition: Validate dates (is past/future/today/weekend/weekday/before/after/in range)
Get Relative Date: Convert to human-readable format (“2 days ago”, “in 3 hours”)
Unix Timestamp Conversions: Convert dates to/from Unix timestamps
Get Holiday Date: Calculate dates for 12 major holidays (New Year, Easter, Thanksgiving, Christmas, etc.)
Get Recurring Date: Calculate recurring dates like “first Monday of March” or “next second Tuesday”

Use Case Example: Create automated reminder workflows that send notifications “2 days before” subscription renewals, or schedule recurring tasks based on business rules like “first Friday of each month.”
