Schedule Bulk SMS Campaigns
Schedule Bulk SMS Campaigns
Scheduling lets you prepare a bulk SMS campaign now and send it at the right moment — when recipients are most likely to read and respond, and within compliance windows.
Available on: Pro Plus plan and above
How to Schedule a Campaign
- Create a Bulk SMS campaign as usual (upload contacts, compose message).
- Instead of Send Now, click Schedule.
- Set the send date and time.
- Choose the time zone:
- Sender's time zone — all messages send at the same clock time, regardless of where recipients are.
- Recipient's time zone — messages send at the specified time in each recipient's local time zone (requires location data in your contact list).
- Click Confirm Schedule.
Quiet Hours Scheduling
Enable Respect Quiet Hours to prevent messages from being sent before 8 AM or after 9 PM in the recipient's time zone.
When enabled:
- Messages that would land outside the 8 AM–9 PM window are held.
- They're sent at the start of the next permitted window (8 AM the following day).
- Held messages are visible in the campaign dashboard with a "Queued — Quiet Hours" status.
Note: Quiet hours apply to the recipient's time zone. If you're sending to recipients across multiple US time zones, the campaign may span several hours as it drips messages into each time zone's permitted window.
Editing a Scheduled Campaign
Before the send time, you can:
- Edit the message — click on the campaign and modify the content.
- Change the schedule — update the date, time, or time zone.
- Add or remove contacts — update your recipient list.
- Cancel the campaign — click Cancel to prevent sending. Cancelled campaigns are saved as drafts.
After the scheduled time, the campaign is locked and cannot be edited.
Best Times to Send
Based on industry benchmarks for business SMS:
| Message type | Recommended send time |
|---|---|
| Appointment reminders | 24 hours before the appointment, during business hours |
| Marketing/promotions | Tuesday–Thursday, 10 AM–12 PM or 2 PM–4 PM |
| Event announcements | 1 week before + day-of reminder |
| Follow-ups | Same day as interaction, within 2 hours |
| Payment reminders | Morning (9–10 AM), 3 days before due date |
Avoid Mondays (inbox fatigue), Fridays after 3 PM (weekend mode), and weekends (unless your business operates weekends and recipients expect it).
