Nowadays my email won't get past your spam filters unless I buy and warm up a reputable domain on a respectable IP address and adhere to the correct content standards. The precise rules for these aren't documented anywhere. Funny enough, the ease of running a mail server and sending email back in the day is probably why it’s so scuffed these days. Email did hit a weird overcorrection though that never evened out, whereas everything else seemed to either standardize or die off (rip the days of telnet’ing into a random domain and being able to actually do things)
