Email alert method

Reading time: 0 minute(s) (0 words)

The email alert method sends customized alert messages to up to 30 different inboxes per alert to notify Nobl9 users whenever an incident is triggered.

Adding the email alert method​

You can add the email alert method directly in the Nobl9 Web application.

Alternatively, utilize the SLOs-as-code approach by:

Nobl9 Web​

  1. Navigate to Integrations > Alert methods.
  2. Click .
  3. Select Email.
  1. Select a Project (mandatory).
    Project is a way to organize your Nobl9 resources and manage access to them.
    When Project is skipped, Nobl9 uses the default project.
  2. Enter a Display Name (optional).
    Spaces are allowed.
  3. Enter a Name (mandatory).
    The name is mandatory and can only contain lowercase, alphanumeric characters, and dashes (for example, my-alert-method-1). Nobl9 duplicates the display name here, transforming it into the supported format, but you can edit the result.
  4. Enter a Description (optional).
    Provide extra details about it, its purpose, responsible persons, etc.
    Up to 1050 characters.

  1. Select Send as plain text (optional) to receive alerts without background graphics and text formatting.

  2. Specify email Recipients (mandatory).
    You can select a category per recipient (at least one recipient in any category, up to 10 recipients in every category):

    • To (default): add direct email recipients

    • Click CC to add carbon copy recipients

    • Click BCC to add blind carbon copy recipients

    • Separate email addresses with spaces, commas (,), or semicolons (;). For example:

      email1@example.com email2@example.com
      email1@example.com,email2@example.com
      email1@example.com;email2@example.com
      email1@example.com ; email2@example.com,email3@example.com email4@example.com
  3. Click Add alert method.
