On your settings page, you will find a section called “Notifications”. Check or uncheck the relevant checkboxes there, hit the blue “Save” button, and you’ll be all set.
I already did that and I’m still getting the same notifications!
Most likely you haven’t linked your accounts under one email address. You may have updated the settings for one email address, but not another. We recommend linking your emails under one account to keep things simple.
Note: “Task” Confirmations Are Always On
When scheduling a task (ex firstname.lastname@example.org), we force a confirmation both for yourself (and if done via the ‘ cc’ field, for the other person as well) regardless of your confirmation settings. This is because the initial task confirmation email provides the only place to complete or cancel the followup.
