폼메일 소스인데 메일로 받을때

내용을 테이블로 작업해서 받고 싶어요.

send파일에서 내용출력하는 부분에 html로 테이블 짜서 넣으면

메일로 html태그가 텍스트로 다 나오는데 혹시 방법이 없을까요?ㅜㅜ

아래 이미지처럼 메일받고 싶어요.

<form name="contactform" method="post" action="send.php">
    <div class="formmail">
        <ul>
            <li><input name="first_name"  type="text" class="ipt" size="30" maxlength="50" placeholder="이름" required ></li>
            <li><input name="email"  type="text" class="ipt" size="30" maxlength="80" placeholder="이메일" required ></li>
            <li><input name="telephone"  type="text" class="ipt" size="30" maxlength="30" placeholder="연락처" required ></li>
            <li><textarea  name="comments" cols="50" rows="10" placeholder="문의사항" required ></textarea></td></li>
        </ul>
    </div>
    <div class="formmail_btn">
        <span><input type="submit" value="전송하기" class="btn btn-red"></span>
        <span><input name="재설정" type="reset" value="다시작성" class="btn btn-black"></span>
    </div>
    </form>
