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.
Warning: Using a Distribution List (DL) as a subscriber can result in any of the recipients on the DL effectively unsubscribing everyone else. For this reason, we strongly encourage you to avoid subscribing a Distribution List to your page, and instead, subscribe individual email addresses.
When they subscribe, they will receive an email with a link to confirm their subscription. The confirmation link must be clicked in order to receive any notifications. This link expires after 90 days.
Once the confirmation link is clicked, the user is taken back to the status page and that's it! As long as they remain a subscriber, they will receive updates when incidents are posted to the page.
Your customers can also subscribe to receive SMS notifications for incidents. SMS messages are not charged individually per message - they are included in the cost of your subscription.
Subscribers with U.S. phone numbers will be subscribed via SMS short-code. This requires confirming the subscription by replying YES to the subscription confirmation message. Subscribers with non-U.S. numbers will be subscribed via long-code, and this does not require confirming the subscription with 'YES'.
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 (this is only for pages that do not have Component Subscriptions enabled). For pages that do have Component Subscriptions enabled, the subscriber needs to click the 'Manage Subscriptions' link in an email notification and then fully opt-out of all component subscriptions on the following screen.
