The Forum Post That Started It

We were browsing the HubSpot Community when we stumbled across this thread about meeting scheduler phone validation. The frustration was real:

"Phone numbers are critical for sales, marketing, and customer success teams—but right now HubSpot’s validation is limited. This often leads to messy data, bad formatting, and even non-existent numbers making it into our CRM."‍

This sort of problem is exactly why we built Clean Dial.

The Problem Users Are Facing

Your meeting scheduler is working perfectly - prospects are booking calls, your calendar fills up, and everything looks great in your dashboard.

Until your sales team starts making calls.

"The number you have dialed is not in service..."

Here's what's actually happening behind the scenes:

• Prospects accidentally typo their phone numbers during booking
• Some intentionally provide fake numbers (looking at you, 555-555-5555)
• International prospects submit numbers without proper country codes
• Mobile numbers get formatted incorrectly and become unreachable

This way, your "qualified meetings" turn into dead ends, and your sales team starts questioning the quality of your leads...

Clean Dial App

We decided to fix it.

Clean Dial works as a HubSpot workflow action that can validate and clean phone numbers after they enter your CRM.

Here's what happens when someone books a meeting with a bad phone number:

Automatic Cleanup: Our workflow action can be triggered when new contacts are created or phone numbers are updated

‍Smart Validation: We check if the number is valid, reachable with the validation action, and save to a custom property on the contact

‍Instant Corrections: Get properly formatted versions of phone numbers (you can then use these in subsequent workflow actions if needed)

‍Clear Flagging: Invalid numbers get marked so your sales team knows not to waste time calling them

The workflow actions give you the information you need to decide what to do with invalid numbers - whether that's flagging them for manual review, putting contacts into a different nurture sequence, or marking them as uncontactable.

A Simple Workaround for HubSpot's Missing Feature

Until HubSpot adds native phone validation to their meeting schedulers, Clean Dial offers a workflow-based solution. You can set up workflows to automatically validate phone numbers as they come in from meeting bookings or any other source.

While it's not the native solution the forum post was asking for, it gives you the data you need to identify which phone numbers are worth calling and which ones will just waste your sales team's time.

‍

How It Works

Setting up Clean Dial is simple:

1. Install the app
2. Create a workflow: set up a workflow that triggers when contacts are created or phone numbers change
3. Add Clean Dial action: drop our workflow action into your automation
4. Clean Data automatically: phone numbers get validated and cleaned as they flow through your system

No complex setup, no form modifications - just add it to your existing workflows and let it work in the background.

‍

More Than Just Meeting Schedulers

While Clean Dial can be used to help solve the meeting scheduler problem, it works as a workflow action for any phone number that enters HubSpot:

• Contact forms on your website
• Lead imports from other systems
• Manual data entry by your team
• API integrations and third-party tools

Set up workflows to trigger Clean Dial whenever phone numbers need validation - whether from meeting bookings, form submissions, or bulk imports.
