KoguNavi

Email & Distribution List Cleaner

Paste copied recipients or a distribution list to extract addresses, remove duplicates, and review syntax or common domain typos before sending.

Unique address list

What it helps with

  • Remove duplicate recipients before sending an announcement
  • Extract email addresses from a copied recipient list
  • Review common domain typos before CSV or CRM import

How to use

  1. Paste addresses separated by lines, commas, or semicolons, including display-name entries.
  2. Clean the list and review invalid, duplicate, or possible typo rows.
  3. Copy the unique line list, BCC-ready list, or CSV report.

Examples

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.
