Why are they marked as SPAM?
Posted: Tue May 20, 2025 9:30 am
1. Many calls in a short time
Making a large number of calls in a short period of time, especially to numbers that haven't given you prior consent to be contacted, can trigger alerts from operators, who may interpret this as an attempt at phone spam. This is common in intensive telemarketing campaigns.
2. Complaints from users
Users have the option to report calls they consider annoying or unsolicited to various institutions and companies. If you receive multiple reports, your number may be labeled as spam. Consumers may also block the number or use apps to do the same.
3. Numbers not registered in public databases
If your number isn't registered correctly or advantages of using our skype database recognized by caller ID services, there's a higher chance it will be flagged as spam.
4. Recycled numbers
If you're using a number that was previously assigned to another person or business, it's possible that the number already had a negative reputation before you acquired it.
5. Automatic algorithms
Spam detection systems often use algorithms to identify suspicious call patterns, such as short call durations or a high rate of unanswered calls.
How can we help you?
When faced with these types of situations, the main challenge for companies lies in the lack of a single "source of truth." Many organizations suffer from being wrongly labeled as spam, and there is no single institution, company, or database where the situation can be easily rectified.
At Numintec, we have two ways to help you:
1. Ensuring the correct registration of the number according to the caller's identity from the very beginning.
2. Providing best practices to prevent SPAM signals.
It's very important to keep in mind that Numintec has no control over the spam lists of various institutions and companies. However, we've provided a list of best practices so you can take proactive measures to prevent this.
What can I do to mitigate the risk?
1. Use verified numbers
We recommend choosing phone numbers that are properly registered and verified by operators in Spain (or the corresponding country). This reduces the chances of your number being considered spam by caller ID services.
2. Personalize and segment calls
You can personalize your calls to make them more relevant and less intrusive. Segment your database and direct your communications to the right recipients, reducing the likelihood of your calls being reported as spam.
