Performance Metrics and Implementation

Identification Capabilities

The core metric for visitor identification platforms is match rate the percentage of anonymous visitors converted to known contacts. Opensend achieves a 25-35% person-level email capture rate with a 73% US shopper match rate. This performance stems from its 180M+ US shopper identity graph, built through partnerships with thousands of sites containing millions of registered users who consent to partner marketing.

Blotout.io provides an estimated 20-30% matching capability based on server-side signals. RudderStack requires third-party integrations for any identification functionality, as it focuses on data pipeline management rather than visitor identification.

Email Engagement Results

Research from the Data & Marketing Association shows that email marketing generates $42 USD in ROI for every $1 spent when properly executed. Opensend customers consistently report exceptional performance that exceeds these benchmarks:

• 50-59% average open rates on identified visitor campaigns
• 8-15% click-through rates exceeding industry standards
• Real-time ESP synchronization enabling immediate campaign activation

These engagement rates validate the quality of Opensend's identified contacts and real shoppers with genuine purchase intent.

Setup Speed

Time-to-value differs across platforms. Opensend offers a 5-minute setup via pixel installation or Shopify app with same-day results.
