We do not send you any messages that you have not explicitly opted to receive or have explicitly asked for.
Check your Mobile Activation page to see the alerts you've previously signed up for.
Remember, email notifications can be requested every time you send an email, so if it is not selected on the above page, you must have inadvertently chosen it when sending.
If you are receiving messages and you have not even registered on this site, then someone is most likely using your phone fraudulently. We never send any messages until the phone has been verified. This means that at some point, the person requesting these messages has previously had access to your phone and has successfully requested and received a message on it. If this is happening to you, then please get in touch with us here, and we will remove your number and the person using your number.
