There are several ways in which your number can be marked as spam:
Recipients can report numbers they suspect as being suspicious spam or spam to their carriers.
Telecom carriers also use complex algorithms to identify potential spam calls. These algorithms look at factors such as call volume inconsistency, short duration calls, and repeated calls to the same number.
Fortunately there are a number of measures you can take to minimize your risk of being flagged as spam.
Best Practices to Avoid Being Flagged as Spam
Moderate your call volume: Avoid making a high number of calls from a single number. If necessary, distribute your call volume across several numbers and avoid calling the same number multiple times in one day. Engaging in high-volume calling, especially if many calls are short or go unanswered, can trigger spam flags
Maintain call quality and increase your call-back rate: Ensure that calls are not consistently short and try to leave meaningful voicemails if the call goes unanswered. This helps demonstrate the legitimacy of your calls.
Apply smart dialing strategies: Consider carefully the time of day you are calling and the appropriate number of attempts to call a number
Enroll your numbers in recognized services: Leading carriers collaborate closely with certain services to clear SPAM labels and link your business identity to your phone numbers. By enrolling in these services, you can enhance the credibility of your numbers and ensure the accuracy of each carrier's data. It's important to note that these are the same entities responsible for tagging calls as "possible SPAM," and their databases may not always be current. The services include:
