Your Reps Waste 5 Hours Every Week Sitting Through Voicemail

At 5% connect rates, your SDR makes 60 dials per day and reaches 3 people. The other 57 calls? Voicemail. That's 5 hours wasted per rep every week — $8,200 per year per rep spent on numbers that never pick up.

You're calling numbers that won't pick up.

Most people don't answer calls from unknown numbers — it's a consistent behavioral pattern. But some people do. Without knowing which contacts on your list actually pick up, your reps are dialing blind — burning through lists and hoping for the best.

Your outbound numbers are showing up as “Spam Likely.”

Carriers like AT&T, T-Mobile, and Verizon are flagging your outbound numbers as “Spam Likely” or “Scam Likely.” Your prospects see the warning label on their caller ID and decline the call. The harder your team dials, the faster your numbers get flagged — and you have no way of knowing until your connect rates have already collapsed.

OptimalDial Fixes Both Sides of the Connect Rate Equation

Know who will pick up — before you dial.

Upload your call list. We analyze the answering behavior behind every number — not just whether it's valid, but whether the person on the other end actually picks up unknown calls. Your list comes back with every contact labeled:

Likely Answer Likely Voicemail Likely Call Screening Not Mobile

Your reps call the Likely Answer contacts first — leading to 25–30% connect rates.

Know when carriers flag you as spam — and we'll fix it.

Add your outbound caller IDs to OptimalDial. Every day, we test each number by calling real AT&T, T-Mobile, and Verizon devices — not APIs, not databases, actual phones. You see exactly what your prospects see. If a carrier flags your number, you get an alert with a screenshot of the flag and we handle the carrier remediation to get it removed.

Common Questions

Talk to us
Does this actually work?
We analyze the answering behavior behind every number on your list. The contacts we flag as ‘Likely Answer’ connect at 25–30% on average — versus 3–5% without. We offer a 14-day money-back guarantee so you can test it on your own data.
Is this just another data provider?
No. We don’t sell phone numbers. You bring your own data from Apollo, ZoomInfo, or wherever you source contacts. We tell you which numbers are worth calling and which to push to other channels.
Do I need to change my dialer or CRM?
No. You upload a CSV and get a CSV back with every contact labeled with an OptimalDial Status. Use whatever dialer you already have.
What about contacts that won’t answer?
Push them to email and LinkedIn sequences. You were probably doing multi-channel anyway — now you know which channel to prioritize for each contact instead of guessing.
How does Spam Label Protection work?
We test your outbound numbers daily on real AT&T, T-Mobile, and Verizon devices — not API lookups. If a carrier flags you, you get an alert with screenshot proof and we handle the remediation for you. Both Answer Intent and Spam Label Protection are included in every plan.
