Overview

Scalendo's September 2025 release introduces an improved Drip Mode for bulk actions that "delivers rock-solid reliability, supports schedules longer than 30 days, and works consistently across every bulk action type."

What is Drip Mode for Bulk Actions?

Drip Mode enables users to "send messages or apply updates to large contact lists in timed batches rather than all at once." This spacing prevents carrier throttling and protects sender reputation.

Key Benefits

• Handles extended contact sequences efficiently
• Improved checkpointing prevents actions from stalling mid-send
• Supports schedules beyond the previous 30-day limitation
• Reusable, configuration-driven engine across all Drip Mode use cases
• Reduced code duplication for faster enhancements

Checkpointing & Automatic Recovery

The system "records progress after every batch." If disconnections or restarts occur, the engine resumes from the last checkpoint, eliminating manual restarts and lost sends.

Beyond 30 Days Scheduling

Previously limited to 720 hours, the new engine allows "any future date—ideal for semester-long nurture series, recurring donation drives, or extended retention campaigns."

Configuration Parameters

• Start On: First batch date/time
• Batch Quantity: 1– 10,000 contacts per run
• Repeat After: Interval in minutes, hours, or days
• Send On: Restrict to specific weekdays
• Process Between: Business hours respecting account time zone
