StatusPage.io can send out notifications to your customers via email and SMS when you create or update an incident.
To see what events trigger notifications, check out Notification Triggers.
Log in to your account and go to the Notifications page. Once there, click the settings tab. Along the right side, you'll see a section where you can customize which subscription types you want to allow. To send email/sms notifications, make sure the relevant checkboxes are checked.
Although subscribers can be created through the API, most subscribers will sign themselves up through your status page.
When they subscribe, they will receive a confirmation message. As long as they remain a subscriber, they will receive updates for incidents.
Below are some screenshots to show the copy we send out for notifications.
End-users can unsubscribe from SMS notifications by replying STOP. (Note: some international carriers don't play nice with sending "STOP" messages, which may require those numbers to be unsubscribed through the UI by a StatusPage admin/team member).
End-users can unsubscribe from Email notifications by clicking Unsubscribe on the email.
