SMS Campaign Scheduling — Send Windows & Business Hours
Define when your campaigns send. Set business hours, time zones, and blackout periods. Messages only go out when you want them to.
Full Control Over Send Timing
Campaigns that respect business hours and recipient time zones.
Send Window Configuration
Define the hours during which campaign messages can be sent: e.g., 9:00–18:00 Monday through Friday. Messages queued outside the window wait until the next open slot. No SMS at 3 AM.
Pause & Resume
Pause a running campaign at any time. Remaining messages stay in queue. Resume when ready — the campaign picks up exactly where it left off.
Schedule for Future
Create a campaign now, schedule it to start next Monday at 10:00. Set it and forget it. SIMtrix will begin sending at the configured time within your send window.
