Here are a couple things you can do to avoid ‘Spam Likely’ if you are using Twilio. For platform numbers unfortunately you can’t check them before purchasing.
Find the number on Twilio you want to purchase. Don’t buy it yet.
Run it through this phone number checker. https://www.truecaller.com/spam-scam-phone-number-lookup
Do not purchase if it shows any signs of SPAM or other issues. Rather find one that shows it’s clear or unknown.
Once purchased register your numbers with Free Caller Registry. It’s free, and helps carriers recognize your business as legitimate. Take advantage of all verification services offered.
If possible, use SIP trunking instead of just platform numbers. This gives you more control over business profiles, caller IDs, and regulatory features like SHAKEN/STIR. Owning your numbers through SIP also makes swapping numbers easier if you run into issues.
Rotate your numbers using a number pool. This spreads your call volume across several numbers, reducing the risk that any single number gets flagged as spam.
Warm up your numbers slowly, just as you would with a new email sender. Start with low call volumes to your most engaged contacts and ramp up gradually. Focus on getting positive call metrics (like answered calls and good sentiment) before scaling up.
