Is anyone else having issues sending emails, when I’m sending my invoices via email not all invoices are being sent

Hello there, lesliesmith67.

We have received several reports regarding this, and our Product Engineers are now working to fix it as quickly as possible. While they do, I recommend reaching out to our Customer Care Team, so you'll be added to the list of affected users (INV-56459). 

To reach them, click the ? Help button at the top-right corner and select Contact Us to talk with a live agent. Ensure to review their support hours to know when agents are available.

Thank you for your patience while we work for a fix. If you have additional assistance while managing your QuickBooks account, let me know. I'll be around to provide further assistance. Have a nice day.
