EasyEmailAPI

EasyEmailAPI is an API-first email verification service that helps businesses and developers check email addresses before accepting signups or using contact lists. Its JSON API can be integrated into a backend to return clear validation signals for individual addresses. Checks include syntax and address components, domain and MX records, disposable and free email providers, role-based addresses, and sub-addressing. The service also offers inbox deliverability and catch-all detection, with SMTP-based checks available on the Pro plan. EasyEmailAPI is designed to support signup-form protection, email-list hygiene, and sales or marketing workflows, but it does not send email or guarantee that a message will be delivered; the company recommends confirmation emails to verify address ownership.

The free plan includes 5,000 checks per month and allows 30 requests per minute. Pro costs $19 per month and provides 100,000 checks, 120 requests per minute, advanced SMTP checks, list-cleanup tools, and priority support. Users can obtain a free API key and consult the documentation and integration guides.
