Advanced multi-server email sending with intelligent rotation and rate control
4 Rotation Strategies
Distribute emails across servers using round-robin, least-used, random, or weighted rotation. Optimize deliverability by balancing load across your PowerMTA infrastructure.
Multi-Threaded Sending
Send through multiple threads simultaneously for maximum throughput. Configure thread count per campaign to match your server capacity and sending goals.
Pause, Resume & Stop
Full campaign lifecycle control. Pause running campaigns, resume them later, or stop completely. Orphan cleanup handles interrupted campaigns automatically.
Template & List Management
Create and manage HTML email templates with the built-in editor. Import email lists, manage recipients, and reuse templates across multiple campaigns.
Delay Modes & Rate Limiting
Configure fixed delay, random delay, or rate-limit mode between sends. Set per-server rate limits to stay within provider thresholds and protect your reputation.
PMTA + Custom SMTP Servers
Send through your PowerMTA servers or any custom SMTP server. Mix and match server types in the same campaign for maximum flexibility.
