Our verdict on LeadFlags
LeadFlags is a deterministic lead-scoring API for sales operations, marketing operations, agencies, call centers, and lead sellers. It accepts JSON lead data and returns a 0–100 quality score, quality level, risk flags, positive signals, and a recommended action. The service is designed to help validate and prioritize leads before CRM ingestion or call-queue routing. Its field detection can handle data such as names, contact details, messages, sources, job titles, industries, company sizes, and websites without requiring a fixed request schema.
Pricing is structured around monthly paid plans. Starter costs €39 per month and includes full scoring and flags, email support, and a production-ready service. Growth costs €99 per month and adds priority processing, fast support, and early access to new scoring logic. Scale costs €249 per month and adds higher rate limits, priority support, and a basic availability SLA. Enterprise adds dedicated SLA and support, an IP allowlist, custom score thresholds, and custom billing and terms. The plans state a 20% annual discount.
LeadFlags fits teams that want predictable rule-based decisions through a web and API service rather than machine-learning predictions. HubSpot and Salesforce integrations cover two common CRM destinations, while the JSON API provides the main route for custom workflows and lead-routing systems. Enterprise controls include custom thresholds and an IP allowlist, and Scale introduces a basic availability SLA. Choose LeadFlags for transparent scoring, filtering, and routing at a defined monthly cost. Teams seeking predictive scoring, account scoring, AI features, or a broader integration ecosystem should choose an alternative.
