Trackly SMS offers flexible scheduling options for your campaigns, from immediate sends to complex recurring patterns.

​
Schedule Types

​
Send Now

“Send Now” is a one-time scheduled send with the send_date set to the current time. There is no distinct “Send Now” mode — it is a convenience shortcut:
  1. Create your campaign
  2. Select Send Now
  3. Click Schedule
  4. A one-time schedule is created with send_date set to now and messages start queuing immediately
“Send now” means messages start queuing. Actual delivery depends on queue size and provider capacity.

​
Scheduled Send

Send at a specific future time:
  1. Select Scheduled
  2. Pick the date and time
  3. Choose timezone (your timezone or contact’s local timezone)
  4. Click Schedule
The campaign will trigger at the specified time.

​
Recurring Send

Send on a repeating schedule:
  1. Select Recurring
  2. Set the send time
  3. Select days of the week
  4. Set a start date and end date (both are required for recurring schedules)

​
Recurring Configuration

​
Days of Week

Select which days the campaign should run:
This sends every Monday, Wednesday, and Friday.

​
Time

Set the send time in 24-hour format:

​
Date Range (Required)

Recurring schedules require both a start date and an end date:
The campaign only runs within this date range. Both dates must be provided when configuring a recurring schedule.

​
Spread Duration

Spread your sends over a time window instead of sending all messages at the exact send_time. Configure spread_duration_minutes (0-120 minutes) to stagger delivery:
This reduces carrier throttling and improves deliverability for large campaigns.
When using local timezone with a spread duration, the system validates that the spread window won’t push past the 9 PM TCPA limit. A schedule with send_time: 20:30 and spread_duration_minutes: 60 will be rejected because it could deliver messages after 9 PM.

​
Local Timezone Sending

Target contacts at their optimal local time:
All contacts receive at 10 AM Eastern, regardless of their location.

​
How Local Timezone Works

  1. The contact’s timezone is stored on the Contact record
  2. The campaign triggers in rolling waves across timezones
  3. Eastern contacts get it first, Pacific contacts later
Contacts without timezone data receive messages in your account’s default timezone.

​
Frequency Capping

Prevent over-messaging with frequency caps:

​
How It Works

When the campaign evaluates a contact:
  1. Check when they last received a message
  2. If within the cap window, skip them
  3. If outside the window, include them

​
Scheduling Best Practices

​
Optimal Send Times

General guidelines (test for your audience):

​
Time Zone Considerations

  • B2C: Local timezone is usually best
  • B2B: Fixed timezone (business hours) may work better
  • Promotional: Consider recipient’s likely activity times

​
Avoiding Conflicts

When running multiple campaigns:
  1. Space sends at least 2-4 hours apart
  2. Use frequency capping to prevent double-sending
  3. Check for overlapping schedules

​
Campaign Calendar

The calendar view for scheduled campaigns is not yet available.

​
Pausing and Resuming

​
Pause a Campaign

Pausing a campaign sets its schedule status to off. To temporarily stop a recurring campaign:
  1. Find the campaign in the list
  2. Click Pause (this sets status='off' on the schedule)
  3. Campaign stops sending new messages

​
Resume a Campaign

  1. Click Resume on a paused (off) campaign
  2. The status is set back to on and it continues from the next scheduled occurrence
Pausing (setting status to off) does not cancel messages already in the queue — it only prevents new messages from being queued.

​
Editing Scheduled Campaigns

You can edit scheduled campaigns before they send: Editing a recurring campaign affects all future occurrences. Past sends are unchanged.

​
Canceling a Campaign

To cancel a scheduled send:
  1. Find the campaign
  2. Click Cancel or Delete
  3. Confirm cancellation
Messages already in the queue may still send. Create a support ticket from your dashboard (Support > New Ticket) to cancel queued messages.
