1) Better email clients This would help people manage their email better. Outlook and exchange are getting better, but still lacking. Gmail has it's threads which work most of the time. Both have proprietary tagging which is not IMAP compatible, which is why Thunderbird suffers. If Thunderbird could handle Exchange and Gmail proprietary nuances it'd be perfect. 2) Better email etiquette The easier your email is to read and comprehend the more likely it'll get responded to. Fix / improve these two then this need to "disrupt email" would fade.
