Information organization isn’t something a mail provider should attempt to solve. A mail provider is a dumb pipe that sends me mail, that’s it. At maximum, a provider can offer features with folders / labels / filters and spam / junk.
Anything that tries to categorize a feed, classify priority or importance, recommend smart replies, etc., is 100% hot garbage for all possible use cases.
Maybe let it be valid for 24 hours or something.
If you solved the captcha then your mail drops into my inbox.
Or maybe you get a webform to say what you gotta say after the captcha. Maybe no attachments unless you fill in a webform and captcha..
Afterwards if i do reply to the mail it goes into a whitelist and you(or perhaps your domain?) don't need to fill in captchas again.
There could tweaks like if you've solved the captcha then you get to email other addresses of my domain without the captcha requirement too.
Or even add the kyc kind of checks like... You get instructions to take a selfie holding a ok sign with your left hand and upload that. And i get to add you to my whitelist after i look at the picture you've submitted...
I can even sort of imagine my phone doing this to incoming phone calls...it answers non-whitelisted numbers with...please dial seventeen plus the cube root of eight....hah
Gmail has "tabs" or whatever they are called which automatically aggregate your emails into different panes. The automatic part didn't work well for me. I'd often find important emails in my "Social" tab, which led to me checking all tabs to make sure the machine learning didn't incorrectly categorize an email.
Hey gives me control over that, and it has been fantastic for the 11 days that I've had an account.
There are other features I love, but the feed has made the biggest impact so far.
A $100 a year for the features that HEY offers isn't worth it to me. I don't have most of the problems that they wrote code for.
The Hey workflow would actually be worse for me, and the lack of custom domains support is a dealbreaker anyway.
