About this app

Y!mobile Mail is the official Y!mobile email app.

You can manage multiple email accounts at once, including Y!mobile email address (@yahoo.ne.jp), MMS/SMS/+Message (*1), Yahoo! Mail, Gmail, etc. (*2), depending on the purpose. This is the definitive email app that has two display formats that you can choose from.

~ Two display formats to choose from depending on the application ~

It is a chat-like format that allows you to easily exchange messages, and you can see the flow of previous interactions and conversations, so it is suitable for casual communication with family and friends.

Additionally, you can automatically sort emails from addresses other than those registered in your phone book, so you won't miss any important emails.

[List type]
This display format is similar to that of a regular mailer, and allows you to check the emails that have arrived in your inbox or personal folders in chronological order. The filtering function also supports automatic folder sorting.

Additionally, you can switch to conversational mode with a single tap from the email details screen, so you can immediately check the conversation up to that point.

・The MMS that can be used are as follows.
・MMS and +Message can only be used when using a SIM contracted with Y!mobile or SoftBank. Even if you have a contract with Y!mobile or SoftBank, some contract plans may not be available.
・+Message is not available on some devices

Compatible with Outlook.com and Docomo Mail

The app looks nice and does seem to work. It's just too bad they are like most Japanese companies that have trouble making their products more accessible to foreigners. It's weird because Softbank their parent company offeres their text/email app in other languages.

1) absolutely horrible, bloated and outdated design. Looks like from late 1990s, wasting screen space. 2) difficult to use. 3) weird DNS requests to various yahoo servers that I had to block on my firewall and reported for Pi-hole lists. Telemetry or logs? 4) no fingerprint support. 5) Backups were difficult to turn off and delete afterwards. No clear privacy policy on data. Are you aware that even for Europeans living in Japan, you, the software maker, must comply with EU GDPR policy?
