Why Calls May Be Marked as Spam

Why Calls May Be Marked as Spam

• High Call Volume: Placing too many calls from the same number in a short period can trigger spam detection systems used by carriers.
• Carrier Thresholds: Many carriers track how many calls a number places per minute, day, or week. For example, making more than around 10 calls per minute can look like robocalling and raise a red flag.
• Short Calls in Large Numbers: A sudden increase in brief calls, especially within a narrow time window, can lead to blocking.
• Repeated Unanswered or Disconnected Calls: Calling numbers that often go unanswered or are disconnected signal potential spam.
• Voicemail-Only Calls: A large number of calls going straight to voicemail can also be a warning sign.
• Complaints from Recipients: When individuals report a number as spam, this contributes directly to a higher risk of being flagged.

Ways to Lower the Chance of Being Flagged

• Use Several Tracking Numbers: Distributing calls across multiple lines reduces the load on each number and lowers the chance of being blocked.
• Follow STIR/SHAKEN Standards: Verifying Caller ID through approved protocols can improve trust and reduce the risk of blocking.
• Call with Intention: Rather than repeatedly calling the same numbers, create a calling schedule that focuses on times when people are more likely to pick up.
• Mix Up Your Outreach: Incorporate SMS and email alongside calls. If you connect through multiple channels, you may need fewer call attempts.
• Speed to Lead Matters: Reaching out to hot leads quickly can boost answer rates and reduce the risk of being flagged.
• Stay TCPA-Compliant and Scrub Lists: Make sure you follow all telemarketing rules, check your lists against Do-Not-Call registries, and honor requests promptly.

Keep in Mind: Call filtering systems are constantly being updated, and carriers don't disclose the exact criteria they use. Sticking to reliable calling best practices can help improve the chances that your calls reach the intended recipients without being flagged.
