Enabling Opt Out by Reply
When sending marketing and promotional SMS, you must comply with anti-spam regulations – below we reference those applicable to Australia and New Zealand. One of the core requirements is that recipients must be provided with a clear and functional method to opt out (unsubscribe) from receiving further messages.
To support this, touchSMS allows you to enable opt-out via SMS reply, which automatically unsubscribes the recipient and adds their number to a designated Opt-Out List. This functionality now includes support for multiple opt-out lists, giving you greater flexibility and compliance control.
🔄 New: Support for Multiple Opt-Out Lists
Previously, opt-outs were managed under a single list per account. With the updated system, you can now create separate opt-out lists to manage preferences by communication type, such as:
-
Marketing
-
Transactional
-
Event Alerts
-
Regional Notifications
This means a contact can unsubscribe from marketing messages while still receiving essential or transactional communications, as long as each message is associated with a different list.
Example: A customer opts out of your “Marketing” list by replying STOP. They will still receive appointment reminders if those are sent using a different opt-out list (e.g. “Reminders”).
✉️ Enabling Opt-Out via Reply
To configure opt-out via reply in your account:
-
Navigate to Opt Out Lists in your dashboard.
-
Click on the Opt Out Settings tab.
-
In the Opt Out Keywords section, enter one or more opt-out keywords (e.g.
STOP,UNSUBSCRIBE,CANCEL) and click Add Keyword. -
Set a Default Opt-Out List to capture opt-outs when a message is sent without a specific list assigned.
-
(Optional) Enable Opt-Out Confirmation SMS to send an automatic reply confirming the recipient has unsubscribed.
-
Click Save to apply the changes.
When a recipient replies using one of your configured keywords, their number will be automatically added to the relevant Opt-Out List.
🗂️ Assigning Opt-Out Lists to Messages
When sending an SMS, you can now choose which Opt-Out List to assign to that message. This allows you to target opt-outs by campaign or message category.
If no list is selected, the system will apply your default opt-out list, which is configured under Opt Out Settings.
🌏 Country-Specific Requirements
Australia
Under the Spam Act 2003 (Cth), all commercial electronic messages must:
-
Identify the sender
-
Contain a clear and functional unsubscribe facility
-
Action unsubscribe requests within 5 business days
touchSMS helps you meet these requirements by enabling keyword-based opt-outs, automated list management, and optional confirmation messaging.
New Zealand
Under the Unsolicited Electronic Messages Act 2007, commercial messages must:
-
Be clearly identified as promotional
-
Include accurate sender information
-
Offer a free, low-cost, or easily usable unsubscribe mechanism
Using reply-based opt-outs with keywords like STOP ensures you meet these standards. You can further customise your sender identity using local sender ID options.
🧾 Sender ID and Reply Handling
The ability for recipients to reply and opt out depends on the Sender ID used:
| Sender ID Type | Supports Reply Opt-Out | Notes |
|---|---|---|
| Shared Local Number | ✅ Yes | Replies are received and opt-outs processed |
| Dedicated Virtual Number | ✅ Yes | Full 2-way messaging supported |
| Custom Sender ID | ❌ No | Replies are not possible — you must include a manual opt-out URL or alternative unsubscribe method in the message |
If you’re using a custom sender ID, you must provide a clear unsubscribe instruction, such as a short link to a landing page where users can opt out manually.
📌 Best Practices
-
Include an opt-out instruction in all promotional messages (e.g. “Reply STOP to unsubscribe”)
-
Assign the appropriate Opt-Out List based on message type
-
Avoid mixing critical messages (e.g. service alerts) with marketing content
-
Use short links or unsubscribe pages when reply handling is not available
