Baremail

Baremail (ベアメール) is a Japanese service from LINK, INC. built around one goal, which its home page states as helping companies with "メールを確実に届ける" (getting email delivered reliably). It is not a campaign editor or newsletter tool. It offers two services: a mail relay that sends a company's own system email faster and with a better delivery rate, and a spam scoring service that analyzes email for problems and diagnoses its health. The home page says customers combine the two according to their environment and situation, cutting the operational work of email delivery while raising delivery rates, and that businesses across many industries use them.

The mail relay service

The Mail Relay Service (メールリレーサービス) handles the mail a company most needs to arrive: automatic notifications such as membership registration, product purchase and reservation confirmations, and bulk sends of important announcements. The home page says a sender only has to point its outgoing delivery at Baremail to get faster delivery and a better delivery rate, so an existing application or mail server keeps generating the messages while Baremail carries them to recipients.

The company's blog describes the relay as SMTP-based. For teams that would rather call it from code, a Web API option can be added to the normal plan, letting systems and applications send through an API. The blog lists what the option covers: bulk sending, merging recipient names into messages, scheduled delivery, and support for implementing one-click unsubscribe. The relay's section of the site has pages on features, functions, use cases, pricing, an onboarding guide and a free trial.

The same blog post explains how to choose between the two connection modes. SMTP suits a team that wants to keep its existing SMTP sending setup and change its application as little as possible, though it may require opening SMTP ports such as 25, 465 or 587. An API call travels over HTTPS on port 443 and suits applications that need to be tightly linked to sending, including handling what happens after a message goes out; the post notes that API sending still uses SMTP for the actual delivery behind the scenes.

Spam scoring, DMARC, SPF and BIMI

The second service, Spam Scoring (迷惑メールスコアリング), checks whether mail risks being misjudged as spam by the receiving side. A sender sends a test email and gets an analysis from several angles, which the page says makes it easy to learn what is keeping mail from arriving and how to fix it. Under this service the site lists three tools: DMARC analysis, SPF hosting, and BIMI deployment support. The DMARC side has outside recognition: the home page reports a "High Performer" award in the DMARC report analysis tool category of the ITreview Grid Award 2026 Spring.

What customers have done with it

The case studies on the home page show the DMARC and scoring tools at work for large senders.

• Chateraise (株式会社シャトレーゼ) reorganized a sending environment of more than 10 million emails a month to deploy BIMI and strengthen protection against spoofing. It raised its DMARC policy to "quarantine" at 100% and now displays its logo through BIMI.
• JP Digital (株式会社JPデジタル) moved the DMARC policy on its main domains to "reject" in just 4 months, and the case study credits Baremail's premium support for making the change run smoothly with a limited team.
• Japan Airlines (日本航空株式会社) used the DMARC analysis function of spam scoring to sort out a very large sending environment, improved its authentication success rate to 99% in half a year, and tightened its policy to reject.

All three are tagged with spam scoring and DMARC analysis, and two of them with reduced operational workload. A press release dated September 29, 2026 announced the Chateraise project.

Pricing

The blog's comparison table lists Baremail's mail relay at an initial fee of 50,000 yen and a monthly fee from 5,000 yen per 10,000 emails, with support by phone, email and online meetings. The 10,000-email figure is the entry point of a volume-based price. The Web API option is an add-on to the normal plan, and the relay can be tried first through the free trial linked from the site menu.

Support

Support is the point the company returns to most. The home page calls attentive, hands-on support (手厚いサポート) Baremail's strength, from the evaluation stage through introduction and after launch: staff first hear out the customer's issues and sending environment and then propose the setup that fits. Anyone with a "メールが届かない" (email is not arriving) problem is invited to get in touch for a consultation. Contact is by phone on weekdays from 9:30 to 17:30 or through a web form, and the blog adds online meetings to the support channels. The JP Digital case study mentions a premium support tier for closer guidance.

The site also carries a blog on delivery problems and authentication, with recent troubleshooting articles on SMTP server errors, the 550 5.7.1 error, SPF softfail versus hardfail, hard bounces, mail not reaching iCloud and modern OAuth 2.0 authentication, a glossary, downloadable guides, events and seminars, a FAQ and a support page, and the Baremail name belongs to a wider "ベア" (Bear) brand that offers other services.

Who it suits

Baremail suits Japanese companies whose own systems send important mail, such as sign-up confirmations, order and reservation notices and bulk announcements, and who want those messages to arrive without rebuilding how they send. It fits especially well where email authentication is on the agenda: the case studies show large senders using the DMARC analysis to reach quarantine or reject policies and to display a BIMI logo. Developers can stay on SMTP or add the Web API option for bulk sends, merge fields, scheduling and one-click unsubscribe. Because the two services can be combined to suit the situation, a company whose mail is being flagged as spam can start with a scoring test to find the cause, while one with many systems sending under the same brand can use the DMARC analysis to map them, as Japan Airlines and Chateraise did, before moving its notification traffic onto the relay.

It is a delivery and diagnosis service rather than a marketing platform, so list building, templates and campaign design stay in the sender's own tools, and the initial fee makes it a planned purchase rather than a quick experiment.
