KAGOYA MAIL is a cloud email hosting service from Kagoya Japan designed for businesses. Its flat-rate pricing model charges a fixed monthly fee regardless of how many user accounts are created, so per-user costs drop as the organization grows.
Every plan includes a dedicated IP address, so outgoing email reputation is not shared with other customers. SPF, DKIM, and DMARC authentication, spam filtering, virus protection, and a firewall are all included. A free trial is available.
Custom Domains
Unlimited domains can be configured on any plan, and one free domain registration is included. Users can also bring domains from other registrars.
WebMail
The Active! mail webmail client is included for smaller plans and works on both desktop and mobile browsers.
IMAP
POP3
IMAP and POP3 are supported with SSL encryption for use with standard email clients on any device. Added on March 26, 2026
