Data cleansing · Bulk and API

Clean the file before it reaches your client or campaign

Bought lists, supplier files, client data and your own database. Clean every file before you deliver it, dial it, email it or put it into a campaign.

Provero shows which records are usable, which need correcting and which should be left out, so the file you deliver or activate is one you can stand behind. Upload a file in minutes, or build cleansing into the way data moves through your business.

  • Upload a file, no integration needed
  • 1.4 million records in one upload
  • API for ongoing cleansing

A file delivered this morning can already be costing you

Bad data is not confined to old databases. A newly bought list, a supplier delivery or a client's own file can arrive with dead numbers, unusable emails, poor addresses and records that should be suppressed.

Every one of those records costs someone. Buyers pay for records they cannot use. Brokers and agencies field rejections, replacement requests and complaints. Direct marketers waste campaign spend. Contact centres waste agent time.

A poor delivery costs more than the records in it. It damages confidence in the next file and the next order.

Data you already hold decays too. People change numbers, close inboxes and move house, so even a good database needs refreshing before each use.

Where uncleaned files cost money

  • Records bought or sold that nobody can use.
  • Rejected deliveries and replacement requests.
  • Client complaints and lost repeat orders.
  • Campaign spend on undeliverable emails and post.
  • Agent time on numbers that never connect.
  • Marketing calls to TPS and CTPS registered numbers.

Why files go out, or go live, uncleaned

A file that opens cleanly in a spreadsheet can still be full of records that do not work. Formatting tells you nothing about whether a number connects or a mailbox exists.

Under delivery deadlines, files are often passed straight on, or straight into a campaign. The problems surface later, as bounces, dead dials, rejections and complaints, when they cost the most to fix.

What Provero finds in every file

Bought, received, supplied or your own, every record is examined for three things. Can it be used? Can it be fixed? Should it be used for this activity at all?

Unusable phone numbers and email addresses

Numbers that do not connect and mailboxes that will not accept mail.

Addresses that need correcting

Incomplete, misspelt and non-standard addresses, corrected and standardised for UK and international post.

Records to exclude

Numbers registered with TPS or CTPS ahead of a calling campaign, and fake, junk or abusive entries that should not be delivered or contacted.

The records to deliver or activate

The usable, correctly formatted records your client, campaign or calling team should receive.

How it works

  1. 1

    Receive or upload the file

    Upload it through the dashboard, or send it in from your own systems.

  2. 2

    Provero cleanses every record

    Each record comes back usable, corrected or marked to exclude.

  3. 3

    Review the results

    See what was corrected or excluded, and why, alongside your original data.

  4. 4

    Deliver or use the output

    Send the clean file to your client, your dialler or your campaign.

What changes

Fewer rejected records and replacement requests

Clients receive files with fewer records to send back.

Fewer avoidable complaints

Less time spent on problems a clean file would have prevented.

Confidence in every file you supply

Deliver data you have checked, not data you hope is fine.

Less wasted calling, email and mailing spend

Spend goes on records that can be reached.

Consistent quality across repeat deliveries

Every batch is held to the same standard, delivery after delivery.

Where cleansing fits into your operation

Before client delivery

Clean outgoing files so the client receives more usable records and fewer reasons to reject the delivery.

After purchasing data

Check a bought email or calling file before you commit campaign spend to it.

Before call centre handover

Remove unusable numbers and screen against TPS/CTPS before the calling file is supplied.

During regular data processing

Clean each incoming or outgoing batch as part of normal operations, not as a one-off project.

Before using your own database

Refresh customer and prospect records before the next campaign.

Who it's for

Direct marketers, data brokers, agencies buying or selling data, lead generators delivering to clients, contact centres receiving calling lists, and businesses cleansing their own customer and prospect data.

Bulk upload, or built into your workflow

Bulk upload needs no integration. For regular volumes, the API can sit in your supplier intake, your file-processing workflow, your delivery pipeline or your CRM, so every batch is cleansed as it moves.

Bulk
Upload a CSV through the dashboard. No developer time.
API
Cleanse each batch automatically as it arrives or before it leaves.

Why Provero for regular files

  • Built for big and frequent files

    1.4 million records have been processed in a single upload, and a typical 100,000-record phone file takes about 15 minutes. Upload as often as your operation needs.

  • Every requirement in one place

    Phone, email, address and calling-list screening on one platform, so a file does not travel between suppliers before it is ready.

  • Processed in the EU

    Your files, and your clients' files, are processed in the EU, so you can tell clients exactly where their data goes.

“We tested Provero as an additional layer for our KYC data provenance due diligence and the outcome reports were very insightful. We could identify data that was part of a legacy breach, data that existed on national suppression files along with detailed phone and email validation flags. Really impressive solution and would recommend to anyone onboarding new data or to check existing datasets. It enabled us at Dataxcel to make informed decisions especially around compliance.”
Lorcan Lynch, Dataxcel

Data cleansing FAQ

Can I cleanse bought or client-supplied files?

Yes. Bought lists, supplier deliveries, client data and your own records are all cleansed the same way.

We handle files every week. Does that work?

Yes. Upload as often as you need, or connect the API so each batch is cleansed as part of normal processing. Rates fall as volume grows.

Will it change my original data?

No. Results come back alongside your records. You decide what to deliver, correct or suppress.

Does cleansing guarantee campaign results?

No. It removes records that cannot work, so your spend, or your client's, goes on records that can. Results still depend on the offer and the audience.

How is this different from Source audit?

Data cleansing prepares a file for delivery or use. Source audit assesses whether a supplier's data meets your requirements before you buy it, accept it or rely on it. Many buyers do both.
