Opting out - Amazon Pinpoint SMS

Opting out

By default, opt-outs are managed by AWS automatically. You can choose to disable this automatic opt-out handling by enabling self-managed opt-outs. Your account can contain both numbers for which opt-outs are managed by AWS, and numbers for which you manage opt-outs yourself. For more information about enabling self-managed opt-outs, see Self managed opt-outs.

Supported opt-out keywords

Where required by local laws and regulations (such as in the US and Canada), SMS and MMS recipients can use their devices to opt out by replying to the message with any of the following:


You can add custom keywords to phone numbers and phone pools to opt-out.



  • END



  • QUIT


  • STOP

  • TD


To opt out, the recipient must reply to the same phone number that Amazon Pinpoint SMS used to deliver the message. After opting out, the recipient no longer receives SMS or MMS messages from your AWS account.


For US toll-free numbers, opt-outs are managed at the carrier level. The only supported opt-out keyword for a US toll-free number is STOP. You can't add additional opt-out keywords, or change the response message that your recipients get when they opt-out. A user can resubscribe by sending a new message to the toll-free using either UNSTOP or START as the keyword.

To configure allowing a user to resubscribe add the keywords UNSTOP, START or both to your toll-free number and set the keyword action to Opt-in. For more information on adding keywords, see Manage keywords.
