How to Clean Your Email List: A Step-by-Step Guide

A practical walkthrough of cleaning your email list using Enrichmatic. From uploading your CSV to downloading verified results, this guide covers everything you need to get started.

Cleaning your email list doesn't have to be complicated. With Enrichmatic, you can go from a messy CSV to a verified, campaign-ready list in minutes. Here's exactly how.

Before You Start

Make sure you have your email list in one of these formats:

  • CSV (.csv)

  • TXT (.txt)

  • XLSX (.xlsx)

Your file can contain up to 1 million email addresses. Don't worry about duplicates — we remove them automatically at no extra cost.

Step 1: Upload Your List

Log into your Enrichmatic dashboard and drag your file onto the upload area. You can also click to browse your files.

Enrichmatic automatically detects the email column in your file. If your CSV has multiple columns (name, company, phone, etc.), we'll find the email addresses and ignore the rest.

Step 2: Review the Preview

Before verification begins, you'll see a preview showing:

  • Total email addresses found

  • Duplicates detected (removed for free)

  • Estimated credits needed

  • Estimated time to complete

This is your chance to confirm everything looks right before spending credits.

Step 3: Start Verification

Click "Verify" to begin. Enrichmatic routes each email through multiple verification providers for maximum accuracy. You'll see real-time progress:

  • Safe to Send — Valid, active email addresses

  • Review — Addresses that need manual review (catch-all domains, role-based addresses)

  • Remove — Invalid addresses, disposable emails, and known spam traps

For larger lists, you can close the browser and come back later. We'll send you an email when verification is complete.

Step 4: Download Your Results

Once verification finishes, download your results as a single, clean CSV file. You have three download options:

  1. Safe emails only — Only addresses verified as deliverable

  2. Full results — All addresses with status columns appended

  3. Flagged addresses — Only addresses that need attention

Understanding Your Results

In the simplified view, you'll see three categories:

| Category | Meaning | Action | |----------|---------|--------| | Safe to Send | Verified, active mailbox | Include in campaigns | | Review | Uncertain (catch-all, etc.) | Decide based on risk tolerance | | Remove | Invalid or risky | Never send to these |

Toggle to detailed view for seven granular statuses:

  • Valid — Confirmed deliverable

  • Invalid — Mailbox doesn't exist

  • Catch-All — Domain accepts everything (risky)

  • Disposable — Temporary address

  • Role-Based — Generic address (info@, support@)

  • Unknown — Couldn't determine (credit refunded)

  • Spam Trap — Known trap address (dangerous)

Tips for Best Results

  • Verify regularly — Email addresses go stale at 2-3% per month

  • Use the Review category wisely — If you have good engagement data, keep engaged catch-all addresses

  • Re-verify before big campaigns — Even a list verified last month can have new bounces

  • Don't skip catch-all resolution — Our multi-provider approach significantly reduces unknowns on catch-all domains

What About Credits?

Remember:

  • Duplicates don't cost credits — removed automatically

  • Unknown results get refunded — you only pay for definitive results

  • Credits never expire — use them whenever you need

That's it. Three steps, clean data, better campaigns.
