The only email client I've ever used for more than a week! I've tried loads of email clients but didn't like the way it took my Gmail inbox which had categories for Promotions etc. and just dumped it into one big inbox. With Polymail, I have my inbox setup so not only do my multiple G Suite accounts all have their own inboxes, but also the original Gmail categorization is preserved. Throw in email tracking (opens, link clicks) and follow up reminders, and I'm sold. Highly recommend.
