What is an SMS blacklist?
An SMS blacklist is a list of phone numbers that have been blocked from sending text messages to a particular recipient or group of recipients. This is typically used to prevent unwanted or spam messages from reaching the recipient.
The numbers on the blacklist can be added manually by the recipient or automatically by a system that detects spam messages. When a message is sent from a number on the blacklist, it will not be delivered and may be rejected or dropped by the carrier.
In addition to blocking unwanted messages, an SMS blacklist can also be used to block unwanted calls or unwanted interactions from numbers that have been marked as spam or have a history of unwanted behavior. This is especially useful for individuals and businesses that receive a high volume of unwanted messages or calls.
An SMS blacklist can be managed and maintained by the individual recipient or by the service provider. Some service providers may offer a way for individuals to view and manage their SMS blacklist, while others may handle it internally.
It is worth noting that an SMS blacklist is different from a caller ID block, which prevents a caller’s phone number from being displayed when they call a recipient. An SMS blacklist blocks messages altogether, while a caller ID block simply hides the caller’s number.
Overall, an SMS blacklist is an effective tool for blocking unwanted messages and calls, protecting the privacy and productivity of the recipient.
