What Japan Unlimited SMTP includes
With Japan Unlimited SMTP, you receive a virtual server with 1 IP and unlimited sending enabled. For bulk campaigns, that means there is no fixed sending cap during the stated 1-day service lifetime.
Just as useful, the authentication layer is already in place. SPF, DKIM, and DMARC are configured, which helps signed email pass checks more cleanly and improves the chances of inbox placement instead of filters or outright rejection.
Mail access, attachments, and bulk mailer compatibility
This service supports Inbox Domain Mail through Roundcube, Cpanel, and Private Domain Mail. That gives users flexible access options depending on how they manage domains and outbound mail accounts.
Attachment sending is supported as well. That matters for standard outreach, document delivery, and transactional email where files need to be included as part of the message flow.
On the integration side, Japan Unlimited SMTP is compatible with all bulk mailers. Whether you use a desktop bulk sender, a browser-based platform, or a custom-built mailing tool, setup is typically straightforward.

Speed and service duration
Sending Speed: Fast. If your goal is quick deployment and immediate outbound delivery, this setup is designed for exactly that kind of use.
