This is a real deal breaker for me, and has led me to look for an alternative and I have a 100% never recommend Quickbooks, which amounts to 17 different potential new customers in the past year.

Here we are in 2024 still not able to do this. I have customer that don't receive the invoices emailed from in QBO at all, let alone landing in spam folders. Soon the email from within the app will stop working altogether.

Can this feature request be prioritised?

Thank you for joining in this thread, Opia. I understand the importance of having to email your customers for your business. Allow me to shed some light on this. 

Please know that we value our customers' feedback to ensure that our product fits your needs. However, we cannot determine if the current feedback is being prioritized since they are randomly read by our product developers. And this may take time to add to the upcoming updates.

I doubt "ABILITY" is the issue on Intuit's end. Think about it. If they send out their own emails, they get more than free advertising. This request is never going to happen unless we all start jumping ship over their greed. And honestly with all the scams we get from people claiming we owe them money through Intuit, as a company IT admin I would also like to block emails like these who are from a "generic" billing company. 

I absolutely agree. Everyone has better and better firewalls every year. This needs to be fixed. I am a company. It is embarrassing to send my invoices from a random outlook address instead of our company address.

Annoyingly I could probably modify the system to integrate with 365 and Google in half a day so really don't know what the problem with doing this is.

With recent SPF/DKIM/DMARC changes from the major provider sending from the intuit domains is worse than ever and we have zero control over it.

Come on Intuit, surely you could spend half a day for a significant improvement.

For folks still looking for a solution to this, Fazeshift (https://www.fazeshift.com/) just launched the functionality to send QuickBooks invoices via email using your own custom domain.

It basically plugs into QuickBooks, grabs the invoice, and sends the email to your customer using your custom domain so invoices stop ending up in spam folders.
