I don't normally write reviews but I am extremely dissapointed with this app considering its a google product. The functionalities in the app are great but I recieve very few, if any notifications for my emails recieved (all the notification settings are fine). I've also sent out a few emails which the recipients either never recieved the email or got it 10-11 hours later Don't take the risk with this app, many others which are very similar and work great.
