Why is this still happening ?! ( July 2024) I've just started using Quickbooks and about a third of my invoices are not being found by my customers until I tell them to look in the Spam folder. Others aren't even finding it in the Spam folder. This is creating delays in payments and cash flow disruption.  This is very disapointing  and creating considerable hassle for both myself and my customers. It's certainly not the sort of thing I want my customers to experience. I thought this was supposed to make invoicing and organising payments easier...but it's done the opposite.
