Opt Out Management
End users who do not want to receive your messages must be able to opt out. ExcelSend manages this for you using a Stop List. Any message sent to a number that's on the stop list is automatically blocked.
If the message you send can be replied to* and if the end user replies with STOP then their number will be added to your stop list.
*Some countries allow an alphanumeric sender id which prevents the end user from replying to the message.
Opt Out Instruction
When sending a message you can choose to add an Opt Out Instruction. This is part of the message and shows the end user a freephone number they can call to opt out. When an end user does this their number is added to your stop list.
