Stop 'spam likely' from costing you deals

Ytel took the time to listen to the problems we had with our previous dialer and made sure to explain how their solutions would solve our problems.

Remove Mislabels & Disputes

Sharpen submits remediation requests on your behalf, disputing incorrect "Spam Likely" and "Scam Risk" labels with carriers. Even numbers already in active use can be remediated without interrupting operations.

Monitor Continuously

Ongoing monitoring catches new flags before they hurt campaigns. Get real-time alerts and automated remediation — so your answer rates stay up without any manual intervention

How It Works

Step 1
Numbers are scanned and audited
Sharpen automatically scans your entire number inventory across carrier databases, checking reputation scores, flag status, and authentication credentials.
Runs continuously, 24/7
Step 2
Numbers are sorted — clean or flagged
Each number is classified based on its health. Clean numbers pass straight through. Flagged numbers — labeled "Spam Likely," "Scam Risk," or similar — are pulled aside.
Automatic classification
Step 3
Numbers take one of two paths
Two paths
Clean numbers
Immediately placed into active rotation and ready to dial.
Flagged numbers
Removed from rotation immediately to protect answer rates while remediation begins.
Step 4
Flagged numbers are queried and remediated
Sharpen submits dispute requests to carriers on your behalf, challenges incorrect mislabeling, and works through STIR/SHAKEN authentication to restore the number's reputation.
Avg. 5–10 business days
Step 5
Remediated numbers placed back into rotation
Once cleared, numbers rejoin the active pool — verified, registered, and protected. Your team picks up where they left off with a clean reputation.
Verified and ready
Ongoing
Continuous monitoring keeps everything clean
The cycle never stops. Sharpen watches every number in real time — catching new flags the moment they appear and restarting remediation automatically, no action required.
Set it and forget it
