How to Automatically Flag and Manage Invalid Email Addresses in NetSuite

📌 Sending follow-up emails to addresses that bounce is a silent drain on any collections program. It wastes staff time, inflates campaign metrics, and can hurt your sender reputation with inbox providers. The good news is that Oracle NetSuite ERP includes native logic to catch hard bounces, flag those contacts, and keep them out of future mailings. You only need to turn on a few preferences and know where to look.

Below is a step-by-step guide to using this built-in safeguard, written for finance and marketing teams that rely on NetSuite for dunning reminders, campaigns, and other collections 

How to Automatically Flag and Manage Invalid Email Addresses

Step 1: See How NetSuite Flags a Hard Bounce

A hard bounce (e.g., due to an invalid domain) triggers automatic actions in NetSuite:

• Logs the email as bounced
  
  
• Flags the email address as invalid
  
  
• Adds a warning banner on the customer or contact record

 No need to monitor inboxes, NetSuite captures these bounce events automatically.

Step 2: Auto-Exclude Bounced Addresses

NetSuite suppresses bounced emails by default, but you can customize this behavior:

Go to Setup > Company > Email Preferences

• Scroll to the Bounce Handling section
  
  
• Set how long NetSuite should suppress invalid addresses (in days)
  
  
• Choose whether to let users reactivate them manually

This keeps your sender reputation intact and prevents unnecessary retries.

Step 3: Review the Bounced Email Address List

Navigate to: Lists > Relationships > Bounced Email Addresses

• Filter by date, contact, or bounce reason
  
  
• Clear bounce flags if a corrected email is provided
  
  
• Update the contact record before resending

 Tip: Run this review before major campaigns to keep your list clean.

Step 4: Watch for Bounce Warnings on Customer Records

Whenever you open a contact or customer with a bounced address, NetSuite will display a prominent alert.

• Update the email address before sending statements or dunning reminders
  
  
• Avoid wasted touches and improve success rates

Step 5: Exclude Bounced Contacts in Searches and Campaigns

• Saved Searches: Add a filter like Email Bounced = False
  
  
• Campaign Groups: Exclude contacts from the Bounced Email Address list

This ensures your lists are fresh and bounce rates stay low.
