Configure Email/SMS Messaging

What is email/SMS used for?

When your users submit a privacy request, you may want to send them messages to do things such as verify their identity or keep them informed of progress on their privacy request. Fides supports email and SMS service configurations for sending processing notifications to your users.

Supported modes of use:

  • Subject Identity Verification -> Used to verify subject identity by sending an OTP (one-time-passord, or code) before proceeding with their privacy request. To learn more about how to use identity verification in subject requests, see the Privacy Requests guide.
  • Request Receipt Notification -> Used to send subject notifications upon privacy request receipt.
  • Request Review Notification -> Used to send subject notifications upon privacy request review. Includes denial reason of the request, if applicable.
  • Request Completion Notification -> Used to send subject notifications upon privacy request completion. Includes link to download data package, if applicable.


Fides currently supports Mailgun and Twilio (SendGrid) for email messaging, and Twilio for SMS messaging.


When using Mailgun, ensure you register or use an existing Mailgun account in order to get up and running with email communications.

Mailgun can be setup to either use Mailgun templates, allowing for customization, or the generic Fides template.

Using Mailgun templates

  1. Within Mailgun create a template named fides
  2. The template can be setup as desired, but needs to contain a {{{fides_email_body}}} variable. This is where the Fides email text will be placed.
  3. In order to use the email template the Mailgun private API key needs to be provided in the Fides Mailgun configuration.

When sending emails Fides will check to see if the fides template is available and use it if so. If a fides template is not found the email will fall back to using the generic Fides email template.

Using the default fides template

  1. Generate a Mailgun Domain Sending Key

    Follow the Mailgun documentation to create a new Domain Sending Key for Fides.

Alternatively the Mailgun private API key will also work for this option, but is not required.

Twilio SMS

To configure messaging via SMS, you will need your Account SID and Auth Token (viewable in the Api keys and tokens section of your account settings), and either your Messaging Service ID or your Twilio sender phone number (both available in your Twilio console).

Twilio SID and Auth Token

Use your messaging service ID if you've set up a specific messaging service in Twilio, otherwise use your Twilio sender phone number.

Twilio Email (Sendgrid)

To configure messaging via email, you will need generate a Twilio API key.

Follow the Twilio documentation to create a new API key for Fides.


Configuring Fides to integrate with a messaging provider can be done either by:

  1. using the hosted UI
  2. or by making API calls, if desired for automation or advanced setup

Using the hosted UI (basic configuration)

To get started, open up the Fides UI, navigate to the "Configure your privacy requests" page (/privacy-request/configure) and select the option to "Configure a messaging provider".

Select the appropriate messaging provider from the given options, enter your configuration details for the given provider, and click Save.

After doing this, Fides will be configured to send messages to users for all types of notifications, using the messaing provider you've selected. Subject identity verification will also be enabled. If you'd like to send only specific types of messages to users, or if you would prefer to not require subject identity verification on privacy requests, please refer to the advanced API calls outlined in the "Using the API" section below.

Below are the attributes you'll need to specify for each messaging provider you'd like to configure. Though you can configure details for multiple different messaging providers, only the selected messaging provider will be used by Fides to send messages at any given point.

Using the API (advanced configuration)

If preferred, you can also make API calls to configure Fides to use your desired messaging provider, rather than using the hosted UI. This may be desirable if you'd like to configure Fides as part of an automated process, or if you require advanced configuration for a specific use-case.

Creating the messaging configuration

First, you can create a default messaging config for the messaging provider of your choice, and provide any non-sensitive configuration details:

Mailgun Config
    "service_type": "mailgun",
    "details": {
        "domain": "{{mailgun_domain}}"

Twilio SMS Config

    "service_type": "twilio_text"

Twilio Email Config

    "service_type": "twilio_email",
    "details": {
        "twilio_email_from": "{{twilio_from_email}}"

Add the messaging configuration secrets

Next, you'll need to add any necessary sensitive configuration values (i.e., secrets) to the corresponding messaging configuration.

Mailgun Secrets
    "mailgun_api_key": "{{mailgun_api_key}}",

Twilio SMS Secrets

    "twilio_account_sid": "{{twilio_account_sid}}",
    "twilio_auth_token": "{{twilio_auth_token}}",
    "twilio_messaging_service_sid": "{{twilio_messaging_service_id}}"

Twilio Email Secrets

    "twilio_api_key": "{{twilio_api_key}}",
mailgun_api_keyYour Mailgun Domain Sending Key.
twilio_account_sidYour Twilio Account SID.
twilio_auth_tokenYour Twilio Auth Token.
twilio_messaging_service_sidYour Twilio Messaging Service SID. One of twilio_messaging_service_sid or twilio_sender_phone_number must be provided.
twilio_sender_phone_numberYour Twilio Sender Phone Number. One of twilio_messaging_service_sid or twilio_sender_phone_number must be provided.
twilio_api_keyYour Twilio API Key.

Set global messaging settings

Lastly, you'll need to update global application settings related to messaging, to ensure messages are sent at the desired points and using the messaging configuration of your choice. Here you can also specify whether you'd like to require subject identity verification on privacy requests, which will also use the specified messaging configuration.

  "notifications": {
    "notification_service_type" : "mailgun",
    "send_request_completion_notification": true,
    "send_request_receipt_notification": true,
    "send_request_review_notification": true
  "execution": {
    "subject_identity_verification_required": true,
notifications.send_request_completion_notificationboolFalseWhen set to True, enables subject notifications upon privacy request completion.
notifications.send_request_receipt_notificationboolFalseWhen set to True, enables subject notifications upon privacy request receipt.
notifications.send_request_review_notificationboolFalseWhen set to True, enables subject notifications upon privacy request review.
notifications.notification_service_typeStringN/ASets the notification service type used to send notifications. Accepts mailgun, twilio_text, or twilio_email.
execution.subject_identity_verification_requiredboolFalseWhether privacy requests require user identity verification.

Check the messaging configuration status

To check that your messaging configuration has been fully configured, you can invoke the following endpoint:

    "config_status": "configured",
    "detail": "Active default messaging service of type MAILGUN is fully configured"

This can help you confirm that you've done what's needed to configure a messaging configuration and that Fides will use during request execution.
