Suppression Match & Remove Tool

Upload a main list and a suppression list, choose match keys, and export a remaining output plus a suppressed output for auditing.

🎯 Step 0: Match Settings
Phone matching can normalize to 10 digits. Custom columns combine values into a single match key.
📁 Step 1: Upload Suppression File

The suppression file contains the numbers/records to remove (e.g. DNC list, opt-outs, existing customers).

📄 Step 2: Upload Main Data File

This is the file you want to clean — rows matching the suppression list will be removed.

Outputs include a remaining file and a suppressed-rows file. Both files are stored privately.

Tool overview

Upload a main list and a suppression list, choose match keys, and export a remaining output plus a suppressed output for auditing.

What is suppression matching?

Suppression matching is the process of comparing a main outreach list against one or more suppression lists and removing rows that should not be contacted.

Operationally, the goal is two exports every run: a remaining list and a suppressed list, with totals that reconcile for QA and reporting.

When to use this tool

  • Before uploading a calling list to a dialer
  • When combining multiple lead sources into one outbound file
  • When you need a suppressed output for auditing and review
  • When manual spreadsheet matching becomes slow or error-prone

Example: main file vs suppression file

Main file Suppression file
lead_export.csv dnc_list.csv
phone / email keys phone / email keys
campaign fields (optional) exclusion reasons (optional)

Matched vs remaining outputs

This workflow separates results into two outputs so teams can move fast without losing auditability.

  • Remaining output: rows not found in suppression (typical dialer-ready list)
  • Suppressed output: rows matched to suppression (review/audit file)

What outputs you receive

  • Remaining export (callable list)
  • Suppressed export (matched rows for review)
  • Counts that reconcile to the input

Matched vs remaining counts

Operational workflows depend on predictable totals. This tool is designed so remaining + suppressed counts reconcile to your starting file.

Audit and reconciliation counts

  • Keep a pre-run input count for the main file
  • Confirm remaining + suppressed totals reconcile to the input
  • Spot-check a small sample of matched keys for accuracy

Why audit-friendly outputs matter

Teams lose trust when rows disappear with no record of what changed. A suppressed export plus clear counts makes suppression workflows reviewable and repeatable.

Who this tool is for

  • Call centers and lead ops teams running suppression workflows
  • Compliance-oriented teams that need auditable outputs
  • Ops teams reducing manual spreadsheet matching

How it works

  1. Upload your main list and suppression list
  2. Select match keys (phone, email, or custom columns)
  3. Run the match to separate remaining vs suppressed rows
  4. Download both outputs with totals that reconcile

Use cases

  • Remove excluded rows before an outbound upload
  • Produce a suppressed export for QA and auditing
  • Standardize suppression workflows across teams

Example outputs

Output What it contains Why it matters
remaining export rows not found in suppression dialer-ready list
suppressed export rows matched to suppression audit and compliance workflow

Security & privacy

Uploads and outputs are stored privately and served via protected download links. Outputs are retained for 30 days by default.

FAQ

Do I get both remaining and suppressed files?
Yes. The workflow is designed to export both outputs so totals reconcile and QA is straightforward.
Can I match on multiple columns?
Yes. Multi-column matching can reduce false matches and better reflect your operational keys.
Are uploads private?
Yes. Uploads and outputs are stored privately and served via protected download links.
