Messy lists cost you money and reputation

Every email campaign you send to a dirty list wastes budget, hurts your sender reputation, and risks landing in spam. Duplicate emails annoy contacts and inflate your subscriber counts. Mixed business and consumer emails mean you're targeting the wrong people with the wrong message.

Most businesses spend hours manually cleaning spreadsheets. ClientRoots does it automatically - in under a minute.

Not just a cleaner - an intelligent list processor

Every other email cleaner just removes invalid addresses. ClientRoots goes further with domain intelligence, lead scoring and smart segmentation.

Three steps to a clean list

1

Upload or paste your list

Upload a CSV or Excel file, or simply paste your email list directly into the text box. Accepts any format - one email per line, comma-separated, or with names in columns.

2

ClientRoots analyses and cleans

In seconds, the system validates each address, removes duplicates, identifies domain types, and segments business from consumer emails - with a full summary of what was found.

3

Download your clean files

Export as separate files: all clean, business only, consumer only. Business plan and above also get a lead quality score alongside each contact.

Common questions

You can upload CSV files, Excel files (.xlsx), plain text files (.txt), or simply paste your email list directly into the text box. ClientRoots automatically detects the email column in multi-column files and preserves all other data (names, phone numbers, etc.) alongside each email.

ClientRoots checks the domain of each email address against a database of known free consumer email providers (Gmail, Yahoo, Hotmail, Outlook, iCloud, AOL, and more). Any email on a custom domain is classified as a business contact. The split is instant and available on Starter plans and above.

Your uploaded email lists are processed and immediately discarded. We do not store, sell or share your contact data with third parties. All processing happens in-session only. ClientRoots is GDPR compliant and registered with the ICO.

Basic duplicate detection removes exact matches (the same email address appearing twice). Fuzzy detection (Business plan and above) also catches near-duplicates - for example, "johnsmith@acme.co.uk" and "john.smith@acme.co.uk" from the same domain, which are very likely the same person. This catches the duplicates that basic cleaners miss.

Your usage limits reset every calendar month. On the Free plan you can clean up to 100 email addresses per month. Starter gives you 5,000/month, Business gives you 25,000/month, and Agency gives you 100,000/month. You can run multiple batches throughout the month - the limit is cumulative, not per upload.
