Good to know
- Syntax checks cannot confirm that an address exists, accepts mail, or belongs to the intended person.
- Common domain typo suggestions are heuristic and are never applied automatically.
- BCC and mail systems can impose recipient limits; check the sending service before a large send.
- The first version accepts up to 5,000 extracted addresses at a time.
FAQ
- Does a ready result mean every email address is deliverable?
- No. The tool checks syntax only. It cannot confirm mailboxes, ownership, consent, or deliverability.
- Are possible Gmail or Yahoo domain typos changed automatically?
- No. A correction is shown as a review suggestion, while the original normalized address stays in the list until you decide.
- Is the recipient list stored?
- No. KoguNavi has no feature to keep recipient lists. Copy the output you need before leaving the page.
