You're right. That's why we initially aimed this tool at hackers, who are expert on categorizing their own data. For regular users, probably your best bet is to filter emails which Gmail determines as "important" by itself. Or, at least, you can filter out for subject "Important", those of your significant other, etc. We'll definitely think this through, thanks for your feedback!
I'd definitely use this if I could just forward specific emails to an address for them to be read out. I'm pretty sure I've implemented this in Asterisk once, years ago, but Asterisk is a real pain. Kudos for seeing it through. Edit: Oh, right, I was assuming you asked for an oauth token to my mailbox, but forwarding makes more sense
We provide an email address, you create some filters, and any incoming message will be read to you.
Feel free to ask if you have more questions!
