Clean Client Lists, Better Campaign Results
Agencies juggle data across dozens of client accounts. Cleanlist helps you verify contacts, clean imported lists, and maintain deliverability standards that keep clients renewing.
The Data Challenges Marketing & PR Agencies Face
Common data quality problems that slow down growth and waste resources.
Client-Provided Lists Are Always Messy
Clients hand you CSV exports from trade shows, purchased lists, and legacy CRMs. These lists are full of duplicates, invalid emails, and outdated job titles that tank campaign performance if you don't clean them first.
Deliverability Problems Kill Client Retention
When email campaigns bounce at 8-15% because of bad data, clients blame the agency. Maintaining sender reputation across multiple client domains requires verified, clean contact data for every campaign.
Scaling Across Multiple Client Accounts
Managing data quality for one client is manageable. Doing it for 20+ clients with different CRMs, naming conventions, and data formats creates operational chaos without a centralized enrichment workflow.
Proving ROI on Data Services
Clients expect measurable results from every dollar spent. Without clear before-and-after metrics on data quality, enrichment rates, and deliverability improvements, it's hard to justify data services as a line item.

Frequently Asked Questions
How do agencies typically use Cleanlist?
+
Most agencies use Cleanlist in two ways: reactive list cleaning (verifying and enriching client-provided CSVs before campaigns) and proactive contact building (finding new contacts at target accounts for ABM programs). The CSV upload workflow handles batch processing for campaign prep, while the API supports ongoing enrichment for clients with active outbound programs.
Can we manage multiple client accounts in one Cleanlist workspace?
+
Yes. Cleanlist supports batch processing with tagging and export controls that make it straightforward to manage multiple client engagements from a single account. You can upload, enrich, and export data for each client separately while keeping everything organized under one billing relationship.
How does Cleanlist help us prove data quality ROI to clients?
+
Every enrichment and verification job produces clear metrics: emails verified vs. invalid, fields filled vs. missing, duplicates found, and job titles normalized. You can share these before-and-after reports directly with clients to demonstrate the value of data services. Agencies often use these metrics to justify ongoing retainers for data hygiene.
What file formats and CRM exports does Cleanlist support?
+
Cleanlist accepts CSV and XLSX uploads with automatic column mapping. It handles exports from Salesforce, HubSpot, Pipedrive, Zoho, and most CRMs. The system auto-detects email, name, company, and phone columns so you don't need to manually map fields for every client export. Processed data exports in the same format for easy re-import.
How fast can Cleanlist process a large client list?
+
Batch processing speed depends on the enrichment depth. Email verification alone processes at roughly 10,000 contacts per minute. Full waterfall enrichment with firmographic data takes 2-5 minutes per 1,000 contacts. A typical 50,000-contact client list goes through full verification and enrichment in under 30 minutes.
