AbstractAPI Email Validation API

API

Real-time email validation for deliverability, spam risk, and syntax checks

Overview

The AbstractAPI Email Validation API provides RESTful endpoints to verify email addresses for deliverability (MX records, SMTP checks), syntax correctness, spam trap presence, disposable domain use, and typo suggestions. Its primary endpoint accepts GET requests with an email parameter and returns JSON responses. Use cases include reducing email campaign bounce rates, ensuring user sign-up data quality, blocking spam registrations, and correcting typos like 'gmail.con' to 'gmail.com'. It integrates easily into apps, forms, and marketing tools.
