I suppose I fall into the artisanal category (postfix,dovecot,spamassassin,roundcube etc). In our case everyone runs mobile/desktop IMAP clients, web mail at least seems to be a "when all else fails" backup plan for quick emails. I do have a specific beef with all the consolidated email providers. If one of them determines your SMTP server to be spam (false-positive), ALL of their clients now reject your email with little recourse for the admin. Just had this happen with a solution that rhymes with 365. Even their clients were clueless as to how to resolve it.
