CardDAV at FastMail
After much work and testing – and then some more work and testing – we’re delighted to announce the release of CardDAV support in FastMail. With CardDAV, you can access your FastMail contacts on your mobile phone, tablet or smart watch, with any changes you make on any device kept in sync – just like IMAP works with your email.
Unlike Apple and Google, you cannot restore your contacts to a particular time.
