1. 00:00What ZoomInfo's fields mean

   ZoomInfo stamps each contact record with a date. Here's what that date covers, and how to check the mailbox before you send. ZoomInfo's API docs list five fields worth knowing here. Email and supplemental email. A valid date. A last updated date. And a contact accuracy score. Your CSV headers may read differently. Start with the valid date. The docs define it as the date the contact record was last validated. That's the record. The definition doesn't say the mailbox was tested that day. The accuracy score has its own definition. Reachable, and still employed at the company listed. So it's a likelihood about a person. You still need an answer from the mail server. And the clock keeps running. People leave. Domains move. The date in your file stays where it is, while the list waits to go out.

2. 00:51Filter before you export

   You can start with fresher records. Through the API, you can require an email on every result. You can keep only records validated after a date. And you can set a minimum accuracy score. ZoomInfo also has a Prepare endpoint for cleaning values, and it's blunt about its isValid flag. That flag only means the input was in good enough shape. It is not a quality judgment. Deliverability, the docs say, comes only from verification.

3. 01:15Verify the export

   If your list leaves ZoomInfo as a CSV, put one check between that file and your CRM or sending tool. Supplemental emails need their own rows if you want them checked. Upload it to File List Verify. Each upload gets its own row in History, with the date you ran it. Now you have a date for the mailbox check too. Large files keep going without you. Results land one address at a time, and you get an email when the job finishes.

4. 01:39Handle catch-all

   One verification result needs a decision, and that's catch-all. ZoomInfo's docs put it well. The domain accepts all addresses, so that one mailbox can't be confirmed. Those leads don't belong in your main send.

5. 01:50Route the results

   Now route each result. Valid goes into your CRM and your normal sequence. Catch-all gets a separate, lower-volume segment. Role gets its own campaign. Unknown waits for review. Invalid and disposable go on a suppression list. Your download keeps your original columns and adds ours at the end. So the old date and today's answer sit on the same row. ZoomInfo's record can change after you export. Your file won't. So before you reuse an old list, verify it again.

6. 02:21What it costs

   On our side, one result costs one credit. That includes catch-all and role. Unknown, bad syntax and disposable cost nothing. File uploads need a paid account, and any credit purchase unlocks them.
