Verify before a campaign
Know your bounce risk before the first email goes out.
Paste or upload the list you are about to send. See which addresses are dead, which are risky, and which people have already left, then download a clean file for your sender.

Typical situations
- You load a bought list into your sender, the bounce rate jumps on day one, and your sending domain suffers.
- A verifier said the email was valid, but the person left the company months ago.
- You run campaigns for clients and need to check their list before it touches your inboxes.
How ListHealth fixes it
- Step 1
Every address checked
Format, mail server and mailbox, with catch-all domains marked as risky instead of hidden as valid.
- Step 2
More than a verifier
A working inbox is not the same as the right person. We also check whether the person still works there.
- Step 3
Straight into your sender
Download a file for Smartlead or HeyReach with only the safe rows, or your original file with a status on every row.
Works with a CSV from HubSpot, Salesforce, Pipedrive, Zoho, Apollo or a spreadsheet. Finding replacements only runs on the rows you pick, and you see what it will use before it starts.
