Use a custom server to send Ory Identity messages to users

The Ory Network comes with SMTP email sending configured out of the box. Ory emails are sent from this address:

{project.name} via Ory <no-reply@courier-eu.mg.oryapis.com>
info

You must send emails using your SMTP server to change the sender address (from_address) and sender name (from_name).

Send emails using your SMTP server​

You can send emails from your own SMTP server. Follow these steps to configure Ory to use a custom SMTP server:

  1. Go to Authentication → Email configuration in the Ory Console
  2. Toggle the Advanced Settings switch
  3. Add the configuration for your SMTP server

SMTP security mechanisms​

SMTP has six different security mechanisms. Most SMTP services today use Explicit StartTLS with trusted certificates.

  1. Recommended: StartTLS with certificate trust verification. This is the most common option today: 
    smtp://username:password@server:port/
  2. StartTLS without certificate trust verification: 
    smtp://username:password@server:port/?skip_ssl_verify=true
  3. Cleartext SMTP uses no encryption and is not secure. This option is often used in development environments: 
    smtp://username:password@server:port/?disable_starttls=true
  4. Implicit TLS with certificate trust verification: 
    smtps://username:password@server:port/
  5. Implicit TLS without certificate trust verification: 
    smtps://username:password@server:port/?skip_ssl_verify=true
  6. Implicit TLS with certificate verification which works if the server is hosted on a subdomain and uses a non-wildcard domain certificate: 
    smtps://username:password@subdomain.my-mailserver.com:1234/?server_name=my-mailserver.com

SMTP Integrations​

Sample connection URIs to send emails via SMTP using different providers.

Mailgun​

Use the following connection URI to send emails using Mailgun via SMTP.

Note: The username and password must be URI encoded.

smtp://{smtp-user}:{smtp-password}@smtp.mailgun.org:587

# For example:
# smtp://some-user%40mailgun.example.org:df2a2c4e-5caa-4f04-85b9-72d54a2468ad@smtp.eu.mailgun.org:587

AWS SES SMTP​

Use the following connection URI to send emails using AWS SES SMTP via SMTP.

Note: The username and password must be URI encoded.

smtp://{smtp-user}:{smtp-password}@email-smtp.{region}.amazonaws.com:587/

# For example:
# smtp://theuser:the-password@email-smtp.eu-central-1.amazonaws.com:587/

Postmark​

Use the following connection URI to send emails using Postmark via SMTP.

Note: The username and password must be URI encoded.

smtp://{YOUR_POSTMARK_SEVER_API_TOKEN}:{YOUR_POSTMARK_SEVER_API_TOKEN}@smtp.postmarkapp.com:587/

# For example:
# smtp://thetoken:thetoken@smtp.postmarkapp.com:587/

Sendgrid​

Use the following connection URI and settings to send emails using Sendgrid via SMTP.

  • Sender address: an email address for a domain that has been verified in SendGrid via Domain Authentication
  • Hostname: smtp.sendgrid.net
  • Port: 587
  • Security Mode: STARTTLS
  • Username: apikey
  • Password: the API key created in SendGrid, with the full “Mail Send” permission (no other permissions needed)
  • SMTP Headers: none If you are unsure which port to use, a TLS connection on port 587 is typically recommended.
smtp://apikey:<YOUR_SENDGRID_API_KEY>@smtp.sendgrid.net:587/

# For example:
smtp://apikey:somekey@smtp.sendgrid.net:587/

Send emails using an HTTP server​

Ory Identities supports sending emails using an HTTP server. This is useful if you want to customize the email content or use a service that doesn't provide an SMTP server.

  1. Go to Authentication → Email configuration in the Ory Console.
  2. Select HTTP Server.
  3. Configure your HTTP server.
  4. Click Save.

Payload​

The payload of the HTTP request is a JSON object that's generated using a Jsonnet template. By default, the following Jsonnet template is used:

function(ctx) {
  recipient: ctx.recipient,
  template_type: ctx.template_type,
  to: if "template_data" in ctx && "to" in ctx.template_data then ctx.template_data.to else null,
  recovery_code: if "template_data" in ctx && "recovery_code" in ctx.template_data then ctx.template_data.recovery_code else null,
  recovery_url: if "template_data" in ctx && "recovery_url" in ctx.template_data then ctx.template_data.recovery_url else null,
  verification_url: if "template_data" in ctx && "verification_url" in ctx.template_data then ctx.template_data.verification_url else null,
  verification_code: if "template_data" in ctx && "verification_code" in ctx.template_data then ctx.template_data.verification_code else null,
  login_code: if "template_data" in ctx && "login_code" in ctx.template_data then ctx.template_data.login_code else null,
  registration_code: if "template_data" in ctx && "registration_code" in ctx.template_data then ctx.template_data.registration_code else null,
  subject: if "template_data" in ctx && "subject" in ctx.template_data then ctx.template_data.subject else null,
  body: if "template_data" in ctx && "body" in ctx.template_data then ctx.template_data.body else null
}

The courier passes the following object as the ctx parameter into the Jsonnet template:

VariableTypeDescription
recipientStringThe email address of the recipient.
template_typeStringThe type of the template. See the list of available templates for a full list
template_dataObjectThe data that should be included in the email. See the list of variables for each template for a full list.

In most cases, the default payload should be sufficient.

HTTP Integrations​

Sample configurations to send emails via HTTP using different providers.

Sendgrid​

Use the following connection URI and settings to send emails using Sendgrid via HTTP.

...
courier:
  delivery_strategy: http
  http:
    request_config:
      url: https://api.sendgrid.com/v3/mail/send
      method: POST
      body: file:///etc/config/kratos/mail.template.jsonnet
      headers:
        "Content-Type": "application/json"
      auth:
        type: api_key
        config:
          name: Authorization
          value: Bearer <API_KEY>
          in: header
...

Here is one example of a Jsonnet body:

function(ctx) {
"personalizations": [
    {
      "to": [
        {
          "email": if "TemplateData" in ctx && "To" in ctx.TemplateData then ctx.TemplateData.To else null)
        }
      ],
     "verificationCode": if "TemplateData" in ctx && "VerificationCode" in ctx.TemplateData then ctx.TemplateData.VerificationCode else null
    }
  ],
  // Other values and personalizations .......
}

Troubleshooting​

In general, if you have problems setting up email delivery, you can view outgoing messages on the Monitoring → Email Delivery page in the Ory Console.

note

The Sent state of an email only indicates whether Ory Identities successfully "handed" off the email to the SMTP server.

Emails do not arrive​

The best way to figure out, why an email did not arrive is checking the Email Delivery dashboard in the Ory Console. It will show all emails sent by your project, along with its delivery state. If the Ory Network could not reach your SMTP server or there was an authentication failure, it will be indicated here along with the error message.

If the email's status is Sent, but it did not arrive, please check the spam folder or the logs of your custom SMTP server (if configured).

Emails are marked as spam​

If you're using a custom domain, but no custom SMTP server, some (or all) emails the Ory Network sends, can be marked as spam or blocked by the email providers of your users, such as Gmail. This is due to the phishing/spam protection these providers have in place to protect their users.

To read more, see Automated Emails but in short: we recommend setting up a custom SMTP server, if you use custom domains.
