  summary: The SendGrid Engagement Quality (SEQ) API allows you to retrieve metrics
    that define the quality of your email program.
  description: "The SendGrid Engagement Quality (SEQ) API allows you to retrieve metrics\
    \ that define the quality of your email program.\n\nAn SEQ score is correlated\
    \ with:\n- The quality of the data in a sender\u2019s program.\n- How \u201Cwanted\u201D\
    \ the sender's email is by their recipients.\n\nBecause \u201Cwanted\u201D email\
    \ and deliverability are closely related, a higher SEQ metric is correlated with\
    \ greater deliverability. This means the higher your SEQ score, the more likely\
    \ you are to land in your recipients' inboxes. See the SEQ Overview page to understand\
    \ SEQ, how it's calculated, and how you can address your score. The SEQ endpoints\
    \ allow you to retrieve your scores and scores for your Subusers."

      operationId: ListEngagementQualityScore
      description: '**This operation allows you to retrieve your SendGrid Engagement
        Quality (SEQ) scores for a specified date range**.

        A successful request with this API operation will return either a `200` or
        `202` response.

        ### 202

        This operation returns a `202` response when SendGrid does not yet have scores
        available for the specified date range. Scores are calculated asynchronously
        from requests to this endpoint. This means a score may be available for the
        specified date at a later time, but a score is not available at the time of
        your API request.

        ### 200

        A 200 response will include all available scores beginning on the `from` and
        ending on the `to` dates specified. The `score` and `metrics` properties will
        be omitted from the response for any days in which the user is not eligible
        to receive a score.

        The `score` property represents a user''s overall engagement quality. The
        `metrics` property provides additional scores for the input categories that
        contribute to that overall score. All scores range from `1` to `5` with a
        higher number representing better engagement quality.

      description: '**This operation allows you to retrieve SendGrid Engagement Quality

        A successful request with this API operation will return either a `200` or
        `202` response.

        ### 202

        This operation returns a `202` response when SendGrid does not yet have scores
        available for the specified date range. Scores are calculated asynchronously
        from requests to this endpoint. This means a score may be available for the
        specified date at a later time, but a score is not available at the time of
        your API request.

        ### 200

        A `200` response will include scores for all Subusers or customer accounts
        belonging to the requesting parent or reseller account. The `score` and `metrics`
        properties will be omitted from the response if a Subuser or customer account
        is not eligible to receive a score for the specified date.

        The `score` property represents a Subuser or customer account''s overall engagement
        quality. The `metrics` property provides additional scores for the input categories
        that contribute to that overall score. All scores range from `1` to `5` with
        a higher number representing better engagement quality.
