Arrow-guided Nazori operation


Nazori Mail Checker prompts you to trace your mouse over the recipient, subject, attachments, and other important information on your PC’s screen. Arrows (⇨) displayed behind important information show you the areas to check with the Nazori operation. Because Nazori Mail Checker sorts in-house addresses (that don't require checking with the Nazori operation) from external addresses (that do require checking), you can see external addresses in the list of recipients at a glance.


Colors inform you when the Nazori operation is needed


Nazori Mail Checker uses deep colors to highlight important information that requires checking with the Nazori operation. The color changes once the check is complete, preventing misdirected email etc.


Nazori operation accuracy determination


If the Nazori Mail Checker determines that the Nazori operation was too routine, too far from the target area, or too fast, it deems the operation invalid and you must perform the check again. This reduces mistakes caused by rushing and can prevent misdirected email etc.


Nazori operation support features help you notice mistakes


You may not notice mistakes if you only trace over information. Nazori Mail Checker displays the areas to check in multiple ways. This includes highlighting characters as you perform the Nazori operation and displaying English email addresses in Japanese. These features make it easy to notice mistakes.


A third-party checking function for double checking


Install Nazori Mail Checker on multiple PCs to make use of the third-party checking function. Work with your managers and colleagues and use the Nazori operation to check each other's recipients, subject, attachments, and emails from each person's own computer.

*Although the third-party checking function does not require a separate server, some set conditions apply (network configuration etc.) Please contact us for details.
