Thanks for following along with the thread, @oldtimer.
How are you today? I hope you're having a great day so far.
At this time, the ability to remove the shaded lines from emails as you can with printing isn't available yet. I understand how beneficial this option would be for you and your business. With that said, I think this is the perfect opportunity to send this suggestion to our Product Development Team . Our Developers review each request and consider them all for future updates. Feel free to use the link I'm including below to submit your request at any time.
However, you do have other customization options when it comes to emailing an invoice in QuickBooks Desktop. To see what options you have available, check out Create custom email templates in QuickBooks Desktop.
Please let me know if there is anything else I can assist you with. I'm happy to lend a hand. Take care!
