I switched from Gmail too a few months ago, setting up my own domain as well. I went with Mailfence, it's slightly cheaper than proton mail (€2.50 per month, but there's also a free tier), and still privacy focused. I think a few things could be improved (no catch all email address available, for example), but for that price I don't think I can complain.

Edit: forgot to add that I used this website to compare different email providers: https://thatoneprivacysite.net/email-section/

That's weird, I'm in Sydney and last year I sent around more than 100 resumes over the span of 6 months, only to land an intern position in a terrible "startup like" company, where I was underpaid and overworked. I had to quit after burning out in a few months. I know of several other juniors with this same issue.

100 applications with almost no luck sounds really bad but there is a possibility you are missing something in your resume. I work in Melbourne, if you want email me your resume and I will take a look to make sure you are not missing something basic.

Thanks for the offer, I appreciate it. I had my resume looked over at Reddit and by other industry professionals, it was just lacking working experience and qualifications (I graduated from TAFE, not uni). I'm not looking anymore, now, as I got a much better job, although not development related (which was, anyway, what I wanted, after burning out).
