Duplicate contact records from NetSuite can corrupt email marketing databases, leading to over-communication with contacts and skewed campaign performance metrics that impact marketing effectiveness.
Here’s how to implement effective deduplication strategies that ensure clean, unique contact data flows to your email marketing platforms.
Prevent duplicates with smart filtering using Coefficient
Coefficient provides effective NetSuite contact deduplication capabilities that prevent duplicate records from corrupting email marketing databases during synchronization.
How to make it work
Step 1. Set up pre-sync filtering for deduplication.
Use email address as the primary deduplication key in Records & Lists imports and apply AND/OR filtering logic to exclude duplicate contact criteria. Filter out inactive or merged contact records and sync only recently created/modified contacts to avoid historical duplicates.
Step 2. Implement SuiteQL deduplication queries.
Create advanced deduplication with SuiteQL using SELECT DISTINCT email, firstname, lastname, company FROM contact WHERE email IS NOT NULL AND isinactive = ‘F’ ORDER BY datecreated DESC. This ensures only unique, active contacts with valid email addresses are synchronized.
Step 3. Handle NetSuite-specific deduplication challenges.
Address NetSuite ‘s dual contact/customer structure that can create sync duplicates and manage same contacts appearing across multiple NetSuite subsidiaries. Clean up legacy contact records with inconsistent data quality and handle custom field variations for the same contact entity.
Step 4. Configure email address and company-based deduplication.
Filter NetSuite contacts where email field is not empty and use SuiteQL DISTINCT clause to eliminate email duplicates. Group contacts by company name using GROUP BY and identify primary contacts per company for email marketing to prevent over-communication.
Step 5. Implement ongoing deduplication management.
Conduct regular deduplication audits to review email platforms for NetSuite-sourced duplicates and refine Coefficient filters based on discovered duplicate patterns. Leverage email platform’s native deduplication during import and monitor duplicate rates to identify data quality issues.
