Once you have registered your Most Contacted people, you can run the phone or the mail by a tapping.
Registration is just pick a person from the address book.

In the email editing screen, you can create an email template.

The source of an icon is not only the address book but also the SD card.

Rinsuke supports email concurrent transmission.
If you send email to multiple people by a tap, please add commas before secondary email address.
( aaa@aaa.com , bbb@bbb.com )

If you want to use # in the phone number, please use the "Edit number before call" option.
Although Rinsuke can not call the phone number containing #, you will be able to enter # in the edit screen.
