I strongly concur with the_macwhisperer and ChuckHull. I typically receive in excess of 300 e-mails a day, across 6 different mailboxes. Between MailHub and MailTags, my productivity is enhanced; without them, I am in trouble. Neither vendor has been able to post an update, due (apparently) to Apple's release of Catalina prior to giving advance notice to developers. That said, if the folks at Dervish software need to create a paywall / annual subscription process, add me to the list of subscribers.
