Podio Email Notifications
In Podio, each user has control over his or her own email notifications.
To control what type of emails you get from Podio, click My account (the silhouette icon) from the top blue bar, then click "Account settings" and the tab "Email & Notifications".
Then in the email settings you can decide for yourself what email you'd like to receive.
Please also tell your colleagues about this setting when you invite them to Podio, so that they can update their settings according to their preferences as well.
