Sorry for the confusion! Google did not tell us they'd be emailing our users like this - the first we heard was when we received the same email on our personal accounts.

This is just about Moo.do's ability to access your emails in Gmail with the Gmail plugin. It won't affect your data at all, and sync with Contacts, Calendar, and Drive will still work fine.

We have a new solution for managing your emails in Gmail, a Gmail Add-On and a Chrome extension: https://www.moo.do/blog/chromeextension. And we have a big update for that coming out within the next week to make it even easier to use. And any emails you've already saved will be transitioned over to the new system.
