This one came from the community.

A user reached out with a feature request: phone verification at the workflow level is great, but they wanted a way to prioritise leads based on how confident we are that the number is real and reachable.

Their logic was simple — if you know a lead’s phone number is solid, route them to sales immediately. If the number looks uncertain, maybe start with email. If the number is almost certainly bad, do not waste a rep’s time calling it.

So we built it. Clean Dial now returns a confidence score with every check.

How It Works

When a contact flows through the Clean Dial workflow action, the response now includes a confidence score alongside the existing phone data (format validity, line type, carrier, reachability status).

The score reflects how confident we are that the phone number is real, correctly formatted, and reachable. A high score means the number passed every check. A low score means something is off — maybe the format is valid but the number is not in service, or the area code does not match the country.

You get a number you can branch on in your workflow, not just a pass/fail.

Routing by Phone Quality

Here is what that looks like in practice:

Score 80+: Priority sales queue. The number is real, formatted correctly, and confirmed reachable. Route the lead to your best available rep. Call immediately.

Score 50–79: Standard queue. The number looks valid but something is uncertain — maybe the HLR check could not fully confirm reachability, or the carrier data is incomplete. Send an email first, then follow up by phone.

Score below 50: Marketing nurture only. The number is likely bad — incorrect format, disconnected, or disposable. Do not waste a rep’s call on this. Keep the lead in a nurture flow and let them re-engage on their own terms.

Why This Matters

Without a score, phone validation is binary — the number is either valid or invalid. That forces you into a hard cutoff: valid numbers get called, invalid ones do not.

But phone data is not binary. A number can be correctly formatted but disconnected. It can be valid but belong to a landline when you need mobile for SMS. It can be reachable today but from a disposable carrier that will be dead next week.

The confidence score captures that nuance. Instead of a binary gate, you get a gradient that lets you match your response to the quality of the data.

Setting It Up

The confidence score is available as a contact property that Clean Dial writes automatically when a record flows through the workflow action. You can use it in any HubSpot workflow branch, list filter, or report.

No additional configuration needed — install Clean Dial, add the workflow action, and the score is there alongside the other phone data properties.

Try It

Clean Dial’s formatting action is free and unlimited. The HLR lookup (which powers the confidence score) includes a free tier to get started.
