Applying as a Email Marketing position

I been doing a lot of freecodecamp and I wanted to start applying. I have a really good understand of HTML and CSS. I been studying JavaScript but more on that later. In the mean time I been apply for a HTML Email Developer position. I figure that would be a great way to get my foot in the door to become a front end web developer. I apply on Linkedin and Indeed. I do get a lot of rejection letter so that means some body is view my resume. I do have a portfolio and I included that in my resume. with a lot of reject letters sometimes it makes me feel like I might not be good enough what can I do to stand out? I included my portfolio and my link to my github Please and feedback is welcome and any advice is also welcome. Thank you for you time.
