Core Concepts

SendLucid assumes some vocabulary. These pages explain the ideas behind the scores and analytics — short, plain, and tied to how SendLucid actually measures things. Read them once and the rest of the product reads easily.

• Email Deliverability — getting to the inbox, and the authentication that earns it (SPF, DKIM, DMARC, BIMI).
• The Deliverability Score — how the 0–100 test score is built from five categories.
• The Analytics Data Model — campaigns, flows, segments, and profiles, synced from your email platform.
• Revenue Attribution — how SendLucid credits email for sales.
• Lifetime Value (LTV) — predicting what a campaign or audience is worth.
• Engagement & Fatigue — opens, clicks, and the cost of emailing too often.
• Finding Opportunities — how SendLucid turns analytics into a ranked list of what to do next.
