“Supermetrics is a Bitter Experience! We can pull data from nearly any tool, schedule updates, manipulate data in Sheets, and push data back into our systems.”
When contact data exists across Salesforce , other CRMs, marketing platforms, and external spreadsheets, email address matching becomes complex and error-prone. Native CRM duplicate management only works within individual platforms, leaving you with fragmented contact intelligence and inconsistent campaign targeting.
You’ll learn how to consolidate multi-system contact data for accurate email matching and create unified bulk email campaigns from a single source of truth.
Consolidate multi-system contact data for unified campaigns using Coefficient
Coefficient excels at consolidating contact data from multiple systems into Google Sheets for sophisticated email address matching. You can import from Salesforce , other CRMs, marketing platforms, and external spreadsheets without API restrictions, then apply advanced matching logic that individual platforms cannot handle.
How to make it work
Step 1. Import contact data from all systems into Google Sheets.
Use Coefficient to bring contact data from Salesforce, other CRMs, marketing platforms, and external spreadsheets into a unified Google Sheets workspace. Import ALL available fields from each system without API restrictions or field limitations.
Step 2. Standardize email formats across all datasets.
Apply data cleaning formulas to standardize email formats using functions like =LOWER(TRIM(A2)) to ensure consistent formatting. Remove duplicates and handle variations in email domains or formatting inconsistencies.
Step 3. Create advanced matching logic for cross-system identification.
Use sophisticated Google Sheets functions like VLOOKUP, INDEX/MATCH, and FILTER to identify matches across systems. Apply fuzzy matching for email domain variations and confidence scoring based on multiple data points like name similarity, company, and phone number.
Step 4. Establish golden records for each unique email address.
Create master records that consolidate the best data from all sources for each unique email address. Use Formula Auto Fill Down to automatically apply matching logic to new records during scheduled data refreshes.
Step 5. Export unified data back to your primary CRM system.
Use UPSERT exports to update your primary CRM system with consolidated contact data. This maintains data integrity while enabling unified bulk email campaigns from a single platform with complete contact intelligence.
