Stop Wasting Months Validating Phone Numbers One at a Time

You know that sinking feeling when you inherit a database and have no idea how many numbers actually work?

Maybe it's a CRM migration.

Maybe it's a new client handoff.

Or maybe it's just years of data that's never been cleaned.

You fire up HubSpot workflows, set up validation one contact at a time... and realize you're looking at 6 months of gradual progress for a 50,000-contact database.

There's a better way!

The Problem with Traditional Validation

Workflow-based validation is great for keeping your database clean over time. You validate new contacts as they come in, run regular cleanup workflows, and slowly chip away at the backlog.

But what about when you need results now??

When you're launching a campaign next week? Or when you just migrated 100,000 contacts and need to know what you're working with?

One-by-one validation doesn't cut it.

You end up with:

- Campaigns launching on unverified data

- Sales reps wasting time on disconnected numbers  

- Connect rates that tank because 20% of your list is dead

- RevOps constantly firefighting data quality issues

Introducing Bulk Phone Validation

We built bulk validation for exactly this scenario.

Instead of validating contacts one at a time through workflows, we take your entire database, validate everything overnight, and have results back to you within 24 hours.

Here's how it works:

1. Book a quick discovery call (tell us your database size)

2. We validate all unvalidated contacts with phone numbers

3. Your HubSpot contacts get updated automatically

4. You receive a detailed report

No workflow setup, no waiting months, no complex configuration.

What You Get

For each contact validated, we check:

- Is the number properly formatted?

- Is the number active and reachable?

Your HubSpot contacts get updated with three key properties:

- `last_validated` - When we checked it

- `phone_validated` - Whether the line is active (true/false)

- `phone_format_valid` - Whether the format is correct (true/false)

Now you can segment, filter, and build lists around data quality.

"Show me all contacts with validated numbers" becomes a one-click filter.

Real-World Scenarios

Scenario 1: The Pre-Campaign Cleanup

A sales team is launching their biggest outbound campaign of the year. They have 50,000 contacts, but no idea how many numbers are good.

Before bulk validation: They'd either launch blind and waste resources on bad numbers, or spend months validating first and miss their launch window.

After bulk validation: 24 hours later, they know exactly which 42,000 contacts are reachable. They skip the 8,000 disconnected numbers entirely, saving hundreds of wasted call attempts and boosting connect rates from 15% to 28%.

Scenario 2: The CRM Migration

A company just migrated from Salesforce to HubSpot. They've got 75,000 contacts, and data quality during migration is always questionable.

Before bulk validation: RevOps would spend weeks spot-checking, slowly validating subsets, and still launching with uncertainty.

After bulk validation: One overnight run reveals 15% of phone numbers are invalid. Now they can prioritize re-enrichment efforts and go live with confidence in their data quality.

Scenario 3: The Quarterly Audit

A well-run RevOps team maintains their database with regular hygiene checks. But with 100,000+ contacts, comprehensive validation is time-consuming.

Before bulk validation: They'd run partial audits, sample random subsets, and accept that they'd never validate everything.

After bulk validation: Every quarter, they get a complete validation report. They maintain database accuracy above 90% and catch disconnected numbers before they impact campaigns.

Why It Matters

Bad data is expensive.

Every disconnected number your team calls is wasted time. Every campaign sent to invalid contacts hurts your metrics. Every quarter you delay cleaning your database compounds the problem.

Bulk validation isn't just about speed - it's about knowing your data is solid before you build on it.

Launch campaigns with confidence. Plan territories around reachable contacts. Report on real pipeline, not phantom numbers.

Getting Started

Bulk validation pricing is straightforward: per-contact pricing.

We validate format and reachability, update your HubSpot properties, deliver a detailed report, and guarantee 24-hour turnaround.
