Verify every lead before it can burn a domain.
Cold email lives and dies on bounce rate. BounceOwl checks each address live before the campaign, separates catch-all and unknown results, and shows you why each verdict was given.
The problem
- Lists that passed and still bounced
- Old results and catch-all domains let bad addresses through. One bad batch can push a sending domain into spam folders.
- Paying for answers you can't use
- Unknown results and repeat checks add up across many campaigns and clients.
- No way to see why
- A bare label gives you nothing to judge a risky lead by, so good leads get thrown out with bad ones.
How it fits your workflow
- 1
Upload the campaign list
Drop in the CSV from your lead source. Duplicates are folded and the cost is shown before it runs.
- 2
Send to valid, decide on the rest
Download valid rows for the campaign. Catch-all and unknown come back in their own files.
- 3
Resolve catch-alls that matter
Run the catch-all check on high-value catch-all leads only. Unclear answers are refunded.
