You can unsubscribe from an email thread by using the "Unsubscribe" button at the bottom of your email. This will only unsubscribe you from that particular email thread. For example, we have a few different emails threads, such as "Weekly Energy Snapshot", "Promotions and offers email", among others.
You can unsubscribe from ALL OhmConnect emails (Except of course #OhmHour notifications. You need those!) on your settings page by going to the "Subscriptions" section, and finding where it says "Click here to unsubscribe from all emails, except for #OhmHour and account recovery emails." at the bottom of the Subscriptions section.
If you'd like to unsubscribe from some, or all SMS #OhmHour notification text messages, you can do so on your settings page in the "#OhmHour Notifications" section.
