TextP2P support for opt-out keywords (SMS STOP filtering)
By default, TextP2P handles standard English-language reply messages such as STOP, UNSTOP, UNSUBSCRIBE or CANCEL for Toll-Free and Long Code messages, in accordance with industry standards. These keywords trigger automatic standard replies from TextP2P. This guide is intended to list the supported opt-out and opt-in keywords for TextP2P Messaging service.
STOP, STOPALL, UNSUBSCRIBE, CANCEL, END, or QUIT
Automated reply: You have successfully been unsubscribed. You will not receive any more messages from this number. Reply START to resubscribe.
Any of these STOP keyword replies will prevent a customer from receiving new messages from the TextP2P phone number they're responding to. When TextP2P receives one of these replies, we will create a "blacklist" entry on our side. Once we have a blacklist entry for a particular recipient phone number, any future attempts to message them will cause the system to auto-filter out those messages with a FAIL status. Recipients can disable this message stop, and resume receiving messages with the START, YES, or UNSTOP commands as outlined below.
Only single-word messages will trigger the block. So, for example, replying STOP will stop the customer from receiving messages from that particular TextP2P number, but replying "STOP PLEASE" or "PLEASE CANCEL" will not. Further, the block works and is logged even if your number currently has no messaging request URL.
START, YES and UNSTOP
Default reply: You have successfully been re-subscribed to messages from this number. Reply HELP for help. Reply STOP to unsubscribe. Msg&Data Rates May Apply.
Any of these replies will opt customers back in to the messages coming from a TextP2P Long Code.
Notice: TextP2P Toll-Free numbers only respond to START and UNSTOP for re-subscribe.
HELP and INFO
Default reply: Reply STOP to unsubscribe. Msg&Data Rates May Apply.
TextP2P does not forward HELP/INFO messages to your incoming message inbox.
When using a TextP2P to send SMS messages, any STOP keyword replies will apply to the entire pool of phone numbers in the account. Similarly, a START keyword will disable our blacklisting for the entire Messaging Service, and allow messages to this recipient once more.
Note that when a user opts-out of receiving text messages they are also removed from receiving Ringless Voicemails automatically by the system. Therefore if you want to tell your customers how they can opt-out in your voicemail message you may. In this situation it's best to leave the caller id field blank so that your TextP2P phone number will be used and the recipient can simply reply with the word STOP by text message.
