Hi, Olivier!!!!
First off, thanks so much for reading and taking the time to reply. Thanks also for your kinds words. They mean a lot for me!
A long time ago, I decided to bet on Gmail as my best email client: 19 Reasons Why Gmail Is the Best Email Client (https://link.medium.com/yY4ZyXWe0ib)
I don’t believe in local email clients. I think they belong to the past.
I'm an Apple's geek, but I do believe in the combination of Apple + Google: How You Can Take The Best From Apple’s and Google’s World (https://link.medium.com/eFCrgBZe0ib)
For me, using Google's gmail is an awesome way to achieve inbox 0 ever day. Here you can see how: The Exact and Easy Workflow I Follow to Achieve Inbox Zero in Minutes Every Day (https://link.medium.com/lSXtfwSe0ib)
Anyway, I think you can integrate your email in Instapaper using Instapaper internal email's address. You just make a forward to that email address, and you can see your forwarded email inside Instapaper without any problem at all.
Tell me if it works!!!!
Take care!!!!
Cheers!!!!
