Looking for a bulk email verifier for free? Apollo isn’t just a powerful B2B lead platform — it also works as a bulk email verifier for free. Just upload your email list, and Apollo will help you clean and verify it in minutes — whether you scraped the emails or collected them from another source.
Here’s how to do it in 4 easy steps:
🚀 Step 1: Upload Your CSV File to Apollo
Start by logging into your Apollo account (a free account works fine). Go to the “Search People” section and look for the option to Import Contacts. Upload your .CSV file that contains the email addresses you want to verify.
💡 Tip: Make sure the email addresses are in a column labeled
🔘 Step 2: Click the “Import” Button
Once your file is mapped correctly, hit the “Import” button. Apollo will begin processing your file and verifying the emails in the background.
📌 Depending on the file size, this might take a few minutes. Also, remember to put a name to the import (the list name).
🧹 Step 3: Filter Verified Leads Only
After the import is complete, go to your contacts and use the filters to show only verified leads. In Apollo, you can filter by email status, selecting only emails marked as “Verified”.
⚠️ Avoid using leads marked as “Risky” or “Invalid” — these can still bounce and damage your sender score.
📥 Step 4: Export Your Verified Emails
Now that you’ve filtered your list, click the Export button to download your clean list of verified emails. You’ll get a fresh CSV with only the valid contacts — perfect for your next outreach campaign.

💡 Final Tip
Apollo’s email verification accuracy is around 75%, so while it’s a powerful free option, you may still need an additional validation tool (like MatchKraft) for 100% precision. That said, 75% accuracy is an excellent deal for a free platform.
