WeGive uses Twilio to send SMS messages, and Twilio automatically handles industry-standard SMS unsubscribe behavior. This ensures compliance with messaging regulations and helps protect your sending reputation.
How SMS Unsubscribes Work
When a supporter replies to one of your SMS messages with specific keywords, Twilio will automatically stop sending future messages to that number and return a confirmation message.
Supported Opt-Out Keywords:
-
STOP
-
STOPALL
-
UNSUBSCRIBE
-
CANCEL
-
END
-
QUIT
When any of these single-word replies are received:
-
Twilio blocks future messages from that number.
-
Twilio sends the following default auto-response:
"You have successfully been unsubscribed. You will not receive any more messages from this number. Reply START to resubscribe." -
You will receive a 400 error if you attempt to send more messages to that number (Error Code 21610).
Note: Only exact keyword replies (e.g.,
STOP
) will trigger an unsubscribe. Messages like “STOP PLEASE” or “PLEASE CANCEL” will not.
How Supporters Re-Subscribe
To resume receiving SMS messages, supporters can reply with:
-
START
-
YES
-
UNSTOP
Twilio will unblock the number and send the following default message: "You have successfully been re-subscribed to messages from this number. Reply HELP for help. Reply STOP to unsubscribe. Msg&Data Rates May Apply."
HELP and INFO Keywords
Supporters can also reply with:
-
HELP
-
INFO
Twilio will automatically reply with: "Reply STOP to unsubscribe. Msg&Data Rates May Apply."
This provides basic help or opt-out instructions. You can customize these responses if using Advanced Opt-Out with a Twilio Messaging Service.
⚠️ If a supporter has unsubscribed,
HELP
andINFO
replies will not be delivered until they opt back in.
Important Notes for WeGive Users
-
Unsubscribes are managed automatically by Twilio. There is no need for you to manually remove numbers from your sending list when they reply with STOP keywords.
-
If you use more than one phone number for SMS campaigns, you’ll need to handle opt-outs across numbers manually. Twilio blocks only the specific number the recipient replied to.
-
For compliance, always include opt-out language like “Reply STOP to unsubscribe” in your SMS messages.
Alphanumeric Sender IDs and Short Codes
-
Alphanumeric Sender IDs (e.g., your brand name) are for one-way messaging only. They cannot receive replies, so STOP/START/HELP do not apply.
-
Short Codes can support STOP/HELP replies, but only if they’re part of a Twilio Messaging Service with Advanced Opt-Out enabled.
If you're unsure whether SMS is right for your campaign or need help interpreting opt-out data, feel free to contact the WeGive support team!
