Sending Windows & Schedules
Control when your campaign emails are sent:
Sending Window — Set the start and end hours for email delivery:
- Default: 9 AM to 5 PM (business hours)
- Supports overnight windows (e.g., 10 PM to 6 AM) for different regions
- If start equals end, the window is 24 hours (always open)
Timezone — All scheduling is timezone-aware using IANA timezone strings (e.g., 'America/New_York', 'Europe/London'). Emails are sent during business hours in the recipient's timezone if you set it correctly.
Active Days — Choose which days of the week to send:
- Default: Monday through Friday (weekdays)
- You can enable weekend sending for certain industries
- Uses 0=Sunday through 6=Saturday notation
How Scheduling Works:
- When a prospect is ready for their next step, the system calculates the scheduled send time (step delay + random jitter)
- If the scheduled time falls outside your sending window or on an inactive day, it automatically advances to the next valid time
- The system scans up to 8 days ahead to find the next valid slot
- Random jitter (1-5 minutes) is added between individual sends to avoid pattern detection
Best Practices:
- Send during your prospect's business hours, not yours
- Tuesday through Thursday typically have the highest open rates
- Avoid Monday mornings (inbox overload) and Friday afternoons (weekend mindset)
- Morning sends (8-10 AM local time) tend to perform best
