EmailScore vs. Hunter.io
Hunter is built for sales development reps finding outbound leads. EmailScore is built for engineering teams protecting signup forms, free trial credits, and cutting downstream verification bills.

1. Two Completely Different Engineering Problems
Hunter.io is an excellent tool for outbound sales development representatives (SDRs) searching for corporate email patterns and scraping professional contacts from LinkedIn. However, using Hunter's verification API as an application security layer at registration introduces massive friction.
EmailScore is engineered specifically for backend engineers, growth teams, and infrastructure leads. It mathematically scores mailbox and domain threat probability in under 5ms, acting as the zero-latency airlock for signup flows.
2. 100x Better Value for Developer Infrastructure
Because Hunter sells to sales teams with high willingness-to-pay, their entry tier charges $49/mo for just 1,000 email verifications ($0.049/check). For an application with 20,000 monthly signups, Hunter costs thousands of dollars.
EmailScore provides 100,000 monthly verifications on its Starter tier for $49/mo ($0.00049/check)—giving software teams 100 times more throughput with sub-5ms edge execution speeds.
