Hello there, @laurelann0119.
Your client will not receive an email about the recurring invoice once it's deleted or canceled in QuickBooks. Make sure that you cancel the recurring transaction before its's scheduled date.
If you'll want to make changes to your recurring template, you can read out this article: Edit a recurring template.
Also, you can refer to this article if you would like to run reports in QuickBooks. It also provides steps on how to email, export, and print reports: Run reports in QuickBooks Online.
Should you have other questions or concerns, please let me know. I'll be right here to lend a hand. Thank you for posting and take good care.
