# Configuring Notifications

You can set up multiple ways to receive notifications when checks in your account
change state. This is useful for several reasons:

* **Redundancy in case of notification failures.** Set up notifications using two
different notification channels (for example, email and Slack). If one transport
fails (e.g., an email message goes to spam), you still receive a notification over the
other channel.
* **Use different notification methods depending on urgency**. For example, if a
low-priority housekeeping script fails, post a message in chat. If a vital service fails,
post in chat, send an email and send SMS.
* Route notifications to the right people.

Each notification method ("integration") belongs to a project:
if you want to use a notification method in multiple projects, you will need to
set it up in each project separately.

In the web interface, the "Checks" page shows a visual overview of which alerting
methods are active for each check. You can click the icons to toggle them on and off:

You can also toggle the integrations by clicking the "ON" / "OFF" labels in
individual check's details pages:

## SMS, WhatsApp, and Phone Call Monthly Quotas

SITE_NAME sets a quota on the maximum number of SMS, WhatsApp, and phone-call
notifications an account can send per given month. The specific limit depends on the
account's billing plan. The quota automatically resets at the start of each month.
The "unused" sends from one month do not carry over to the next month.

When an account exceeds its monthly limit, SITE_NAME will:

* Send a warning email to account's primary email address
* Show a warning message in the **Integrations** page


## Repeated Notifications

If you want to receive repeated notifications for as long as a particular check is
down, you have a few different options:

* If you use an **incident management system** (PagerDuty, VictorOps, OpsGenie,
PagerTree), you can set up escalation rules there.
* Use the **Pushover** integration with the "Emergency" priority. Pushover will
play a loud notification sound on your phone every 5 minutes until the notification
is acknowledged.
* SITE_NAME can send **hourly or daily email reminders** if any check is down
in any of your projects.
Set them up in [Account Settings › Email Reports](../../accounts/profile/notifications/):

## Monthly Reports

SITE_NAME sends monthly email reports at the start of each month. Use them
to make sure all checks have their expected state and nothing has
"fallen through the cracks."

A monthly report shows checks from all your projects.
For each check it lists:

* check's current status
* the number of downtimes by month, for the last two months
* the total downtime duration by month, for the last two months

You can opt-out from the monthly reports in the
[Account Settings › Email Reports](../../accounts/profile/notifications/) page
or by clicking the "Unsubscribe" link in the email report's footer.
