What messages you will receive
Messages sent under this programme are limited to transactional status updates for a support request or demo booking that you submitted yourself. Each message identifies KEEN BEST and references the specific request or booking it relates to.
| Event that triggers a message | What the message tells you |
|---|---|
| Request received | Confirms that we received your support request or demo booking, and confirms your SMS subscription for that request. |
| Status changed | Tells you the new status of your request when our team updates it. |
| Request resolved | Tells you that your request has been closed or resolved. |
| Booking confirmed | Confirms the date and time of a product demonstration you booked. |
| Booking reminder | Reminds you of an upcoming product demonstration you booked. |
We do not send marketing messages, promotional offers or newsletters through this programme. Messages are sent only in response to a request that you initiated.
Message frequency
Up to 6 messages per request. If you submit more than one request, each request has its own set of updates. We do not send recurring messages outside the lifecycle of a request you submitted.
Cost
We do not charge you for these messages. Message and data rates may apply from your mobile carrier depending on your plan. Contact your wireless provider for details of your text plan or data plan.
How you opt in
You opt in on our public web form at https://keenbest.com.tw/support/sms-updates-optin.html. You must actively select a dedicated SMS consent checkbox that is not selected by default. The mobile number field only becomes available after you select that checkbox, so we do not collect a mobile number and no message is sent unless you have consented.
The SMS consent checkbox is optional. You can submit a support request or book a demo without opting in to SMS updates, in which case we reply by email only. Consent to receive text messages is never a condition of receiving support or booking a demonstration.
How to stop receiving messages
- Reply STOP to any message to cancel.
- Reply HELP to any message to request help.
- You may also contact us at support@keenbest.com.hk or +852 2511-0933 to have your number removed.
If you reply STOP to a message sent from a United States toll-free number, the opt-out is applied by the mobile carrier at network level. We cannot override or reverse it on your behalf, and no further messages can be delivered to your number from that toll-free number.
To resume receiving messages, reply UNSTOP or START to the same number. Submitting a new support request on our website is not sufficient to restore delivery after you have replied STOP.
Supported regions
SMS status updates are available to mobile numbers in the United States, including the US territories of Puerto Rico, the US Virgin Islands, Guam and American Samoa. Availability in other regions may be added over time and will be reflected on this page.
Carrier and delivery
Messages are delivered through mobile carriers using messaging infrastructure operated by Amazon Web Services on our behalf. Delivery depends on your carrier and your device. Carriers, including US mobile carriers, are not liable for delayed or undelivered messages.
