About this plugin
SentWatch monitors WordPress email delivery reliability with instant notifications when problems occur.
The plugin sends periodic “heartbeats” to our monitoring service. If these signals stop arriving, it means your site has stopped sending emails (SMTP issues, plugin conflicts, server problems), and we notify you immediately.
Key Features:
- Hybrid Heartbeat System – Uses HTTP API with email fallback for maximum reliability
- Automatic Time Sync – Plugin synchronizes with server time to prevent false alarms
- Instant Notifications – Get alerts immediately when email delivery fails
- Zero Configuration – Just enter your API key and you’re done
- Lightweight – No performance impact on your site (runs in background)
- Smart Scheduling – Heartbeats are automatically aligned with server expectations
How It Works:
- Plugin sends a “heartbeat” signal at regular intervals
- Our server tracks when heartbeats arrive
- If a heartbeat is missed, we verify your site is reachable
- If the issue persists, you receive an instant email notification
Subscription Plans:
- Free – 1 site, 24-hour monitoring interval
- Silver – 10 sites, 12-hour interval
- Gold – 50 sites, 6-hour interval
- Platinum – 200 sites, 3-hour interval
Note: This plugin requires a free account on SentWatch.
