Some clever customers of my email productivity tool (mentioned above) had a similar sentiment. They figured out a way to forward their emails to my service thereby keeping both separate and still benefitting from my tool. It prompted me to write up a how-to for Gmail which could be tweaked for any provider in theory: https://www.paced.email/articles/how-to-auto-forward-specifi...
But I don't want to trust, and pay for, multiple email providers. It increases cost, complexity, liability and lock-in. I'd prefer an email productivity tool that is a downloadable desktop/mobile app that I can start/stop using with no friction.
