How to Set Up Email Domains and Signatures in NetSuite

📌 Unbranded or unauthenticated emails often end up in spam folders or go ignored by recipients. Without DKIM authentication and professional signatures, even legitimate messages from Oracle NetSuite can appear suspicious. Setting up branded domains and email signatures builds credibility, enhances email deliverability, and reinforces your brand identity.

Steps to Set Up Email Domains and Signatures 

Step 1: Configure Email Domains (DKIM)

• Navigate to Setup > Company > Email > Email Preferences
  
  
• Go to the Email Domains (DKIM) subtab and enter your branded domain or subdomain in the Domain Name field
  
  
• Click Verify DNS Entry to start the verification process
  
  
• NetSuite will provide CNAME records to be added to your domain provider’s DNS settings
  
  
• Once added, send a test message to a DKIM reflector address to confirm the setup
  
  
• This enables DKIM authentication, allowing recipient servers to confirm your emails are from a legitimate source
  

Step 2: Customize Email Preferences and Signatures

• Go to Home > Set Preferences > User Profile
  
  
• In the Signature field, enter your preferred email signature using HTML formatting
  
  
• Include branded elements such as company logo, tagline, and contact information
  
  
• In the From Email Address field, specify the desired branded sender address (optional—defaults to login email if left blank)
  
  
• While creating Email Templates, select your configured email domain to replace NetSuite’s default domain
  

Step 3: Maintain Consistency Across Templates and Users

• Standardize email templates across teams to maintain uniform tone and branding
  
  
• Share signature templates for users to paste into their preferences for consistent external communication
  
  
• Regularly review and update templates and signatures to align with current branding guidelines

Benefits of Using Branded Email Domains and Signatures

• Enhanced Sender Reputation: DKIM builds domain credibility, preventing spoofing or impersonation
  
  
• Improved Deliverability: Authenticated emails are less likely to be filtered as spam
  
  
• Professional Appearance: Consistent branding creates a polished, reliable impression
  
  
• Increased Trust: Familiar domains and clear identity cues reassure recipients that the email is legitimate
