I recently concluded a successful job hunt with a protonmail address. I used `@pm.me` alias, which I guess didn't ring any alarm bells.
As an extra bit of authenticity I've been smime signing my sent mail. Not encrypting, just signed. I figure that something no spamer is going to do and I’m hoping any spam filter will look at and pass it. Assuming they don't ignore it and make it a waste of time.
