Email app myMail has unveiled a version of the app for the Apple Watch, as well as several updates to the iOS and Android versions. The iPhone and iPad apps now incorporate biometric security, with Touch ID access to email.

A recent survey of the email habits of 600 American adults in relationships carried out by myMail provider, My.com, found that a more powerful authentication and authorization method is needed when it comes to protecting email privacy. One third of respondents said they had accessed their partners’ email, and over 12 per cent said they do it every chance they get.

“While native apps and top email providers have existed for years, their approach to how users’ email data should be protected on mobile remains the same,” said My.com founder, Dmitry Grishin. “As myMail launched in November 2013 as a mobile-only email service, we can implement security features focused solely on mobile. With myMail’s new Touch ID support, those who let others use their mobile devices will feel more secure in knowing that their email is safe.”

Other new myMail features include themed design templates to enable users to make emails more expressive, as well as the ability to insert emoticons into emails without a dedicated emoji keyboard. Other updates include the ability to open links in Safari or myMail, and the option to see only unread email, all flagged or important email, or just email with attachments.
