I reinforced knowledge about how to manage forms with react-hook-form

const {
  register,
  handleSubmit,
  formState: { errors },
} = useForm();
const emailRules = {
  required: "Email is required",
  pattern: {
    value: /^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,}$/i,
    message: "Email is invalid",
  },
};

<FormContainer onSubmit={handleSubmit(onSubmit)}>
  <Field>
    <Messages>
      <p className="fw-bold color-charcoal-grey">Email address</p>
      {errors.email && <Span>{errors.email.message}</Span>}
    </Messages>
    <Input
      type="email"
      placeholder="[email protected]"
      {...register("email", emailRules)}
    />
  </Field>
  <button className="btn fw-bold color-white fs-normal">
    Subscribe to monthly newsletter
  </button>
</FormContainer>
