The Most Accurate Email Verification API for Developers & Marketers

PilotVerify achieves 99.6% accuracy through a multi-layered verification process including syntax checks, DNS/MX record lookup, disposable domain detection, and optional SMTP mailbox verification. Our validation database is updated continuously to maintain industry-leading accuracy.

Syntax validation confirms an email address is correctly formatted (e.g., name@domain.com). SMTP verification goes a step further — it connects to the recipient's mail server and checks whether the specific mailbox actually exists. SMTP is more thorough but takes slightly longer, while syntax + MX record checks are instant and catch the vast majority of invalid addresses.

Yes. You can upload a CSV file directly in your dashboard or send batches through our API to validate thousands of email addresses at once. Each batch produces a detailed report with validation status, deliverability score, and risk flags for every address.

Every email verification consumes one credit, whether the result is valid, invalid, or risky. Credits never expire and are shared across API calls and bulk uploads. You only pay for what you use — no monthly fees or minimum commitments.

API requests will return an insufficient credits error. You can purchase additional credit packs anytime from your dashboard with instant activation. There are no automatic renewals or surprise charges.

Most developers complete their first integration in under 30 minutes. We provide a RESTful API with full documentation, ready-to-use code examples in Python, JavaScript, PHP, Ruby, Go, and more, plus instant API key generation upon signup.

We store validation results — including status, checks performed, and timestamps — for your account history and analytics. Email addresses are encrypted at rest and automatically purged after 90 days. We never sell or share your data with third parties.
