Thanks for bringing this to my attention, christophec.
I'd be happy to help you get this issue straightened out right away and ensure that you'll receive the email reminders moving forward.
Based on what you've mentioned, it seems like our Intuit Sender Address might've been marked as Spam by your email provider at one point. To fix this, you'll need to set our service related email address as a Safe Sender or whitelisted on your email account.
I'm including this article for the steps on how to set this up on supporting email providers: How to make sure you receive important email messages from Intuit
That should do it. I'm confident that you'll be all set to receive the reminders again in the future.
Please keep me posted should you need more help with the setup. I've always got your back. Thanks for coming to the Community, wishing you and your business all the best!
