End users who do not want to receive your messages must be able to opt out. DiaryBook manages this for you using a Stop List. Any message you try to send 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.
When sending a message you can choose to add an Opt Out Instruction. This is part of the message and shows the end user an opt-out link that they can click to opt out. When an end user does this their number is added to your stop list.
So what is a Stop List? This is a list of mobile numbers connected to your DiaryBook account that have requested to be opted-out of any future text messages from you.
How does it work? Every time you send a text message to a list of numbers, the list is sanitized against your Stop List. Any message that is intended to go to a mobile number on the Stop List is blocked.
The operation is automatic and aids in keeping you compliant with many data protection laws for your peace of mind.
