Bounced Back Emails_Zoho CRM

Hello Everyone,

We've set up a workflow rule to automate sending Renewal Reminder emails to our clients, with this, bounced back emails are inevitable. What could be the possible ways to prevent this from happening? Is there a way we could solve this?

Also, is it possible that we could monitor the emails that are bounced back? or Is there a monitoring that we could use for our reference? or a notification email?

Answers and ideas would be greatly appreciated. Thank you!
