How to Schedule Bulk SMS in Australia
TL;DR: In SMSFlow you schedule bulk SMS when you compose the message by picking a later date, time, and timezone. Review upcoming sends in the scheduled messages report and cancel any that no longer fit (you cannot edit a scheduled message).
Schedule bulk SMS in 5 steps
-
Open Send SMS and choose recipients
Select contacts, one or more groups, paste Australian numbers, or import a CSV of recipients. Confirm the list is the one you want for this delayed send. -
Write or pick the message
Type the text, paste it, or choose a saved template. Use placeholders such as{first_name},{last_name}, or{stop_message}if you want personalisation. Check the message preview and the credit estimate (some messages use more than one credit). -
Turn on scheduling and set the timezone
Instead of sending now, choose the option to schedule for a later date. Set the date and time, and select the timezone that matches when your audience should receive the SMS. Account timezone defaults live under Maintenance → Account → General if you want a consistent baseline. -
Confirm credits and submit the schedule
Review total credits for the batch, then confirm. The messages sit as scheduled rather than going out immediately. New Australian business accounts need email, ABN, and related verification before any send (including scheduled ones) can proceed. Sign-up includes 50 free credits. -
Review or cancel from the scheduled report
Open Report → scheduled messages to see what is still queued. If plans change, remove or cancel the scheduled item. You cannot edit the content, time, or recipients after it is scheduled—cancel and create a new send if you need changes.

Why timezone matters
Bulk SMS for Australian businesses often needs to land in business hours or just before an event. Scheduling with an explicit timezone reduces the risk of messages going out at the wrong local time when your team and customers sit across states. Set a sensible default timezone in account settings, then double-check the schedule picker on each send.
What you can and cannot change later
The scheduled messages report is built for oversight: see what is coming up and cancel what you no longer want. There is no edit path for a scheduled job. That keeps the queue simple, but it means you should treat the compose step as final—preview the message, recipients, and credit count carefully before you confirm.
Credits, verification, and Australian numbers
Billing is per credit, not strictly one credit per SMS; longer or more complex messages can use more. Check remaining credits under Account → Billing and see current pricing before large batches. SMSFlow is for Australian businesses with a valid ABN; sending targets Australian numbers on the web platform (no desktop or mobile app). You cannot send until verification steps are complete.
After messages go out
Once a scheduled send runs, track outcomes in the dashboard and Sent reports (date range, status filters such as delivered or failed). Inbound replies from numbers you have messaged appear in Inbox; reply via Send SMS, not from Inbox. If you use a Sender ID, recipients cannot reply to those messages.

FAQ
Can I edit a scheduled bulk SMS?
No. You can only remove or cancel a scheduled message. Create a new send if the copy, time, or list needs to change.
Where do I see upcoming scheduled messages?
Use Report → scheduled messages. It lists what is still waiting to go out so you can review or cancel.
Do I pick a timezone when I schedule?
Yes. When you schedule from Send SMS you set a later date and time with a specific timezone. You can also set an account default timezone under Account → General.
When are credits used for scheduled SMS?
Credits are part of the send model (some messages use more than one credit). Check the credit counter on compose and your balance under Billing before you lock in a large schedule. See pricing for how credits work.
Can recipients reply to a scheduled message?
If you send from a number that supports replies, inbound messages show in Inbox and you reply via Send SMS. If you use a Sender ID, recipients cannot reply.
Who can use SMSFlow for scheduled bulk SMS?
Australian businesses with a valid ABN (validated), subject to email, mobile, 2FA, and related checks before sending. Non-business email domains may need extra review.
