Companies who don't listen to their users [ or worse... lecture them! ] are unlikely to do well.
I use one more step with email and it works well for me - finding anything is easy. You can order by date. Outlook lets us search any search string for any directory tree [your Zip Code example].
I learned a long time ago that if you give the same task/objective to different talented people thy often approach it differently. Even their use of software and tool preference is likely different. There is no right way, and rarely an 'only way'. Flexibility empowers people.
So many of your users have explained this, endlessly. Clearly you are not listening.
You should be enabling users, not lecturing them.
Your approach however is to say … actually, doing that our side is hard - so you all adapt your working habits to us.
