Remove Bounced Emails From a List: Clean It Before You Resend
To remove bounced emails from a list, export the bounces from your sending tool, delete the hard bounces from your main list, suppress them so they are never added back, and then verify what is left before you resend. SimpleVerifier Pro does the verification for $39 a month: the first 100,000 checks a month at full speed, then slower, never cut off. Try 100 free checks first, no card.
Step by step
- Export the bounce report from your email tool, with the bounce type if it gives one.
- Separate hard from soft. A hard bounce is permanent. A soft bounce is temporary; if the same address soft-bounces in several sends, treat it as hard. Our SMTP deferral versus bounce post explains the difference.
- Delete hard bounces from the main list and add them to a suppression list, so a later import cannot bring them back. See cold email suppression lists.
- Verify the remaining addresses. Removing bounces only deals with addresses that already failed. An old list has more that have not failed yet. Upload the file to the verify page or the CSV email verifier.
- Export valid, risky and invalid separately. Send to valid first. Send risky in small batches and watch bounces.
- Resend and check the new bounce rate. If it is still high, read why cold emails bounce.
For the file handling itself, see remove invalid emails from a CSV.

When another vendor is cheaper
If this is a single clean of a list under 100,000, a prepaid pack from Reoon or DeBounce costs less than a month of Pro, and you pay once. A monthly plan fits when bounces keep coming because you add new lists regularly and want to verify each before sending. The Reoon and DeBounce pages show costs at different list sizes.
Bottom line
Remove and suppress the bounces, then verify the rest so the next send does not bounce again. Try the free 100 checks on a slice of the list to see how much more is hiding in it.
Common questions
How do I remove bounced emails from my list?
Export the bounced addresses from your sending tool, add the hard bounces to a suppression list, delete them from the main list, then verify the remaining addresses before you resend.
What is the difference between hard and soft bounces?
A hard bounce is a permanent failure such as an address that does not exist. A soft bounce is temporary, such as a full mailbox or a server problem. Repeated soft bounces on the same address are usually treated as hard.
Do I need to verify after removing bounces?
Yes if the list is old. Bounced addresses are only the ones that failed in that send. Others on the list may fail next time.
How much does it cost to verify the rest?
SimpleVerifier Pro is $39 a month with the first 100,000 checks a month at full speed, then slower, never cut off. You can try 100 free checks first, no card.
