You can manage your email notification settings any time here:

On this page, you can select which email notifications you'd like to receive, and the time you'd like to receive them. You can also add a phone number if you would like to receive text messages from Walkadoo.
Please note that it's not possible to "pause" your Walkadoo account if you'll be away, however you can toggle your email and text notifications on and off at any time.
