I've been using Pangram's Gmail inbox labeler for about two months now. It's been pretty huge to be able to see cold emails labeled as AI and use this info to inform how I want to engage.
With this feature, there was a big discussion internally about privacy. Zero data retention (ZDR) -- where Pangram doesn't store the result after processing -- is a policy typically reserved for enterprise customers. However, since email data is much more sensitive, we ended up deciding to turn on ZDR for all email inbox scans. No email inbox data will be retained by Pangram, and this applies equally to everybody.
The other really important thing here was to give users a choice of what happens to their email. My preference today is to simply label AI emails but leave them in my inbox. This may shift In the future if AI emails ramp up in volume, so we have the option to make fully AI emails skip the inbox or go straight to spam.
Please try it out and let me know any feedback you may have!
