1. 00:00How Lead411 keeps data fresh

   Lead411 rechecks its whole database on a schedule. Here's what that means for the file you already downloaded. That's the promise on Lead411's site. Every record comes back around, and bad or outdated data comes out. That schedule runs inside the database. A file you exported sits outside it. Nothing touches a CSV after the download, and the CSV is what reaches your sending tool. Those rechecks are thorough. Lead411 names three methods. SMTP, human verification, and email open validation. The third one is unusual. A message goes out, and an open from a real person marks that address as valid. An open tells you the mailbox worked on that day. Inside Lead411, pick verified data first. Its FAQ encourages exactly that. There's also verification in real time, and an option to send records to its data team for a 24 hour re-verification.

2. 00:56When to check again

   Lead411 says you don't need another tool to clean its data. Right after export, that's a fair place to start. A second check earns its place when the list has waited, when you've merged other sources in, or when you're reusing an old file. Lead411 can export to CSV, a CRM, or marketing automation. If you want that second check, choose CSV, so the file stops here first.

3. 01:19Verify the export

   Open File List Verify, and drop in the export. The email column gets picked out, repeats are collapsed, and you see the credits before you commit. Your download keeps your original columns and adds ours on the end. We've used generic headers here, so yours may read differently.

4. 01:33Read the results

   Catch-all needs a word. Lead411's FAQ treats those emails as their own case, with separate tools behind them. So an address it calls verified can still show catch-all here. That only means the mail server won't confirm that mailbox to us, and the sending decision is yours. Sort the rest before anything gets imported. Valid heads to your CRM or sequence. Catch-all gets a smaller, separate segment. Role gets a campaign written for shared inboxes. Unknown waits for review. Invalid and disposable go on your suppression list.

5. 02:04Import the clean list

   Then import this file, and not a fresh Lead411 export. A new export can bring back the rows you just removed. For us, every result costs one credit, catch-all and role included. Unknown, bad syntax and disposable are free. Uploading files takes a paid account, and any credit purchase unlocks it.
