How to Avoid Spam Caller ID's through SalesAi and Twilio

Follow this guide to learn some tips to avoid your Ai Agent calls showing up as Spam Caller ID's.

Overview:
When you’re making hundreds of outbound calls a day through Twilio and SalesAi, it’s not uncommon for your phone numbers to start showing up as “Spam Likely” or “Scam Risk” on caller ID. This guide walks you through a few smart ways to reduce the chance of that happening so you can keep your connect rates high.


📱 1. Purchase Multiple Phone Numbers & Rotate Them Regularly

Why it matters:
Using the same phone number too often can lead carriers to flag it as spam, especially if the number makes a high volume of outbound calls.

How to do it:

  • Log in to your Twilio account and purchase several phone numbers (at least 3-5 is recommended).

  • In your SalesAi Agent, manually switch your agent’s phone number every week.

  • Rotate through your purchased numbers so no single number gets overused.

Pro Tip:
Set a recurring reminder to swap numbers each Monday. Keeping usage balanced across multiple lines is a great way to fly under the spam radar.


🔄 2. Create a Weekly Sequence to Monitor Spam Flags

Why it matters:
Some spam flags show up gradually. The best way to catch them is by simulating a regular outbound call to yourself.

How to do it:

  1. Add yourself as a contact in SalesAi.

  2. Create a basic SalesAi Voice Agent.

  3. Build a sequence that uses this agent and includes multiple call steps.

  4. Delay each step by 7 days. 

  5. Add yourself to the sequence.
  6. Let the calls come in once per week.

⚠️ Do not answer these test calls. If you answer, the sequence will stop. Just let them ring so you can see how the caller ID appears. Look for any “Spam Likely” warnings on your phone.


🧠 Final Thoughts

Twilio spam labeling isn’t always predictable, but these proactive steps help lower your chances. Keep rotating your numbers and keep a pulse on how they appear. Regular checks and smart habits can make a big difference in your answer rate.
