Scheduling an SMS Sending

When sending an SMS campaign, if you choose to schedule the sending for a later time/date, a lot can change before the scheduled time.

For example, people may sign up for communication from you; a few others may unsubscribe between the time you set up an SMS sending and the actual time of the sending. Or, you could want to make some changes to a scheduled campaign.

Wondering what happens in the scenarios mentioned above?

As a rule of thumb, we freeze the sending details 30 minutes before the scheduled sending time.

Let us look at the different ways in which this impacts your sendings:

Scenario I – SMS Sending is Scheduled for a Time that is Less than 30 minutes away from the Current Time

For example, if the present time is 5 pm, and the user schedules an SMS sending for a time between 5 pm to 5:30 pm.

In this Scenario

This sending’s distribution details will be frozen immediately, i.e., at 5 pm.

  • The user will not be allowed to make any changes to the SMS content or the recipient groups.
  • The SMS campaign will be sent to all the contacts that were a part of the recipient group(s)/ dynamic group(s) at 5 pm. This means that in case a contact, which was a part of the recipient group at 5 pm, but he/she unsubscribed from the mailing list at 5:15 pm, he/she will still receive the SMS campaign. Similarly, if a contact gets added to the recipient dynamic group at 5:20 pm, he/she will not receive the SMS campaign.

Scenario II – SMS Sending is Scheduled for a Time that is More than 30 minutes Away from the Current Time

For example, if the present time is 5 pm, and an SMS is scheduled for sending at any time later than 5:30 pm, let’s say at 10 pm.

In this scenario

  • The user will have the option to edit the SMS (both content and distribution details) until 45 minutes before the scheduled distribution time, i.e., until 9:15 pm in the above example.
  • The user will have the option to cancel (delete) the SMS sending until 30 minutes before the scheduled sending time, i.e., until 9:30 pm in the above example.
  • The sending details for this SMS campaign will be frozen at 9:30 pm, i.e.,
    • The user will not be allowed to make any changes to the SMS content or the recipient groups.
    • The SMS campaign will be sent to all the contacts that were a part of the recipient group(s)/ dynamic group(s) at 9:30 pm. This means that in case a contact, which was a part of the recipient group at 9:30 pm, but he/she unsubscribed from the mailing list at 9:45 pm, he/she will still receive the SMS campaign. Similarly, if a contact gets added to the recipient dynamic group at 9:50 pm, he/she will not receive the SMS campaign.
