# Notification Profile Types

> Once you have alarms configured in Ignition, you can notify people when alarms occur. Ignition provides three Notification Profile Types:  Email, SMS or text message, and Voice through a phone call in Ignition. All three of these notification profiles can be configured to be two-way which can be acknowledged via email, or by text message, or by pressing 1 on the phone. Here is a brief description of each Notification Profile Type:

- [Email Notification Profile](email-notification-profile.md) - simply sends an email containing the alarm notification message. The two-way sends an email containing links that allow the user to acknowledge the alarm.
- [SMS Notification Profile](alarming\alarm-notification\notification-profile-types\sms-notification-profile.md) - sends a text message to users notifying them of an alarm, and a link to acknowledge the alarm.
- [Voice Notification Profile](voice-notification-profile.md) - delivers alarm notifications to users via telephone. Acknowledgement is provided as a voice instruction as part of the call.

Details on how to create and configure each of these profiles are found on the following sub-pages.

## Module Requirements
Each Notification Profile requires the [Alarm Notification Module](getting-started\ignition-modules\core-modules\alarm-notification-module.md). This is because Notification Pipelines are managed and defined by the Alarm Notification Module. The [SMS Notification Module](getting-started\ignition-modules\core-modules\SMS-notification-module.md) and [Voice Notification Module](getting-started\ignition-modules\additional-modules\voice-notification-module.md) are similar in concept to browser plug-ins in that they extend the functionality of another piece of software. The SMS Notification and Voice Notification are both separate modules, and can be downloaded from the [Ignition Downloads webpage](https://inductiveautomation.com/downloads/ignition/8.1.31). To learn more about installing these modules, refer to [Installing or Upgrading a Module](getting-started\installing-and-upgrading\installing-or-upgrading-a-module.md).

### Additional Requirements
Each Alarm Notification Profile needs a method to deliver the message. These methods are not included with the Alarm Notification Module, and some may require additional hardware to be purchased.

- **Email Notification** - The Gateway will need network access to an SMTP server.
- **SMS Notification** - A cellular modem with an active SIM card. Alternatively, a Twilio account may be used instead of the physical cellular modem.
- **Voice Notification** - Any SIP compatible phone system.
