CRM & sales ops

Your CRM has more dead numbers than you think.

Years of accumulated contacts, bounced WhatsApp and SMS campaigns, reps guessing which numbers are even still worth trying. Bulk-verify your existing list and get a clean file back.

The cost

The rot you can't see until you look

Nobody adds a bad number to a CRM on purpose — it arrives as a typo, a number someone's since changed, a lead that went cold years ago and was never cleaned up. Roughly 1 in 5 phone numbers submitted through forms are disconnected or fake to begin with, and that rate only grows as a list ages. Every campaign you run against an unverified list is paying full price to reach a database that's quietly gone stale.

How FILTER fits

Bulk-verify what you already have

No new workflow to build — export the column you already have, upload it, get a verdict back on every row.

1
Export your CRM's phone number column as a CSV.
2
Upload it — up to 1,000 numbers a batch — or call the API directly if you're automating this.
3
Get a file back with a verdict on every number: CONNECTED, ABSENT, or UNDETERMINED.
4
Route ABSENT contacts out of active campaigns without deleting the record — you decide what happens next, we just tell you what's real.

What you get back

The same verdict shape, once per row, so your cleaned file drops straight back into whatever you exported it from.

{
  "country": "IN",
  "valid": true,
  "status": "CONNECTED",
  "carrier": "Vi",
  "line_type": "MOBILE",
  "is_ported": false
}

For a bulk cleanup pass, status and valid are all most teams act on — CONNECTED stays in rotation, ABSENT gets suppressed, UNDETERMINED gets retried later.

Your CRM has more dead numbers than you think.
