i've been using a rather 'rare' two letter tld for my e-mail address since forever. besides the typical autocomplete in forms to suggest to change it to a more common tld, it seems to work quite well for me. People also don't seem to have an issue remembering the tld as it seems to match closely with the common tld used within my country, but distinctive enough to not forget. .party as tld might not be the best idea of course, considering you might want to be taken seriously in your future e-mailing endeavors.
