Why Score Your Email List
Not all email addresses are equal. A scored email list lets you prioritise outreach, tailor messaging and allocate resources to the contacts most likely to convert:
Benefit
How scoring helps
Impact
Better segmentation
Group contacts by score range for different treatment
Higher open and click rates; lower unsubscribe
Resource allocation
Focus sales outreach on high-scoring contacts
Higher conversion; lower cost per acquisition
Send frequency decisions
High-score contacts get more frequent emails; low-score get less
Better engagement; fewer complaints
List cleaning decisions
Zero-score contacts are candidates for removal
Smaller, healthier list; lower ESP costs
Campaign targeting
Score-based segments get different offers and content
Higher relevance; better ROI
Reactivation timing
Score trends show when contacts are disengaging
Intervene before they lapse

Threshold review
Quarterly
Review score thresholds; adjust if too many or too few contacts in each tier
Model validation
Quarterly
Compare scores against actual conversions; do high-score contacts convert more?
New signal addition
As needed
Add new scoring signals when new data becomes available
Score reset
Annually
Consider full recalculation to prevent score inflation
Preparing Data for Scoring
Before scoring, ensure your email list is clean and deduplicated. Upload all contact data from CRM exports (CSV), ESP exports (CSV), event registration lists, website form submissions, purchased lists and other sources to Email Extractor to extract and deduplicate email addresses. Duplicate contacts inflate scores (the same person scored twice appears as two leads) and skew engagement metrics (opens and clicks split across duplicate records make each copy look less engaged than the person actually is), so deduplication before scoring ensures accurate, actionable scores.
