This diff introduces a single utility for sending emails but violates several critical guidelines, most seriously exposing secrets and lacking explicit types. Top issues are related to security, type safety, and configuration. |

[blocker] SENDGRID_KEY is hardcoded directly in the source: const SENDGRID_KEY = "SG.XXXXXXXXXXXXXXXXXXXXXX.YYYYYYYYYYYYYYYYYYYYYY";
Suggestion: Remove the API key from the code and reference it via a process.env.SENDGRID_KEY environment variable. Ensure the key is stored in a .env file.

[blocker] Sensitive data (FROM email) is hardcoded: const FROM = "no-reply@example.com";
Suggestion: Move the FROM email value to an environment variable and access it using process.env.FROM_EMAIL.

[major] sendEmail's function arguments are untyped: sendEmail(to, subject, body)
Suggestion: Explicitly type all arguments, e.g., sendEmail(to: string, subject: string, body: string).

[major] sendEmail lacks an explicit return type.
Suggestion: Specify the function's return type, e.g., Promise or the precise response shape, not relying on type inference.

[major] No error handling is present for the fetch API call. Failures will throw uncaught exceptions.
Suggestion: Wrap the fetch call in try/catch and handle or propagate errors appropriately.

[minor] Raw string URL and email type are hardcoded as magic strings: "https://api.sendgrid.com/v3/mail/send", "text/plain".
Suggestion: Move URLs and fixed values to named constants, or, if configurable, into environment variables.
Automated Code ReviewScore: 🟡 80 / 100
The code generally follows proper modularity, type safety, and configuration principles, but there are major issues with input validation and the shape of returned data. Error handling and non-hardcoded configuration are well-applied, but schema and contract enforcement is weak at the API boundary. |

[major] No runtime validation of the input parameters is performed before passing them to the SendGrid API (e.g., to, subject, or body).
Suggestion: Add validation for parameters (to, subject, body) at the start of the function, rejecting improperly formed or empty values before proceeding.

[major] The function promises an explicit EmailResult return type, but returns the parsed response.json() object, which is not guaranteed to match the EmailResult interface.
Suggestion: Explicitly shape and check the response JSON to match EmailResult before returning, or map/validate its structure before returning.
